Step-by-step explanation:

By using exactly four 4s it is possible to write a few numbers: at least from 0 - 30.

=> For example, using exactly four 4s, we can write 1 as follows

1 = 44 / 44

The right hand side of the above equation has exactly four 4s and solving it will give 1.

=>Using exactly four 4s, we can write 2 as follows;

2 = (4/4) + (4/4)

Also, there are exactly four 4s in the right hand side of the above equation and solving it gives 2

=> Using exactly four 4s, we can also write 6 as follows;

6 = 4 x .4 + 4.4

The above equation also contains exactly four 4s which will give 6 when solved. i.e

(4 x .4) + 4.4 = (4 x 0.4) + 4.4 = 6

The expressions for numbers 1 through 10 using exactly four 4s have been tabulated and shown in the image attached to this response.

Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.

We have,

Let's start by finding the total number of points that Carlos can earn in the class:

Total points

= 5 quizzes x 20 points per quiz

= 100 points

If Carlos needs an average of 90% or greater, that means he needs to earn at least 90 points out of 100.

Total points earned.

= 18 + 19 + 17 + 20

= 74 points

To find the minimum score Carlos needs on the final quiz, we can set up an inequality:

(74 + x) / 5 ≥ 0.9

where x is the score on the final quiz.

Simplifying this inequality.

74 + x ≥ 90

x ≥ 16

Therefore,

Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.

Answer:

A is the answer.

Step-by-step explanation:

We have

\( \sqrt[3]{56 {x}^{7} {y}^{5} } \)

Factor the radical by taking perfect squares of the real numbers and the exponents.

56 can be made up of perfect 8, x^7 can be made up of x^6 and y^5 can be made up of y^3. So we get

\( \sqrt[3]{8 {x}^{6} {y}^{3} \times \sqrt{7xy {}^{2} } } \)

Take the cube root of 8x^6y^3.

Which is 2x^2y.

\(2 {x}^{2} y \sqrt[3]{7xy {}^{2} } \)

A is the answer.

3x² (3 - 8x³)

Explanation:

you have to find the GCF first (greatest common factor)

and then, divide each term by the GCF

\( {3x}^{2} ( \frac{9x ^{2} }{ {3x}^{2} } + \frac{ - 24 {x}^{5} }{ {3x}^{2} } )\)

now, simplify each of the term in parentheses.

if you do it correctly, you'd get 3x² (3 - 8x³) as the answer.

Answer:

3x^2(3 - 8x^3)

Step-by-step explanation:

9x^2 - 24x^5 = 3x^2 (3 - 8x^3)

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

= 3x^2(3^(1/3) - 2x)(3^(2/3)+ 2*(3^(1/3))x + 4x^2)

The coefficient of \(x^{7}\) is 16796160.

For this, we have to find the coefficient of \(x^{7}\) in \((3x+4)^{10}\)

General Term: This term symbolizes all of the terms in the binomial expansion of (x + y)^n.

The general term in the binomial expansion of (x + y)^n is

T(r+1) = nCr x^(n-r)y^r.

Here the r-value is one less than the number of the term of the binomial expansion. Also, nCr is the coefficient, and the sum of the exponents of the variables x and y is equal to n.

We can use the general term for this.

\(T_{r+1} = (nCr) a^{n-r} x^{r}\)

Since we have to find  \(x^{7}\),

\(T_{3+1} = (10C3)(3x)^{7} 4^{3} \\T_{3+1} = [(10C3)3^{7} 4^{3} ]x^{7}\)

This is the coefficients of \(x^{7}\)

Calculating,

10C3 = 120 (using combinations)

\(3^{7} = 2187\\4^{3} = 64\)

Therefore, multiplying the 3,

Coefficients of \(x^{7}\) = 120 * 2187 *64

= 16796160

Answer:

If y represents the distance Jordan still has to walk after x hours, then the equation \( y = -2x + 13 \) describes the given equation.

The y-intercept of the equation represents total distance of the trail

Step-by-step explanation:

A linear equation can be written to represent the situation above using the slope-intercept equation form, which is given as \( y = mx + b \)

Where,

m = slope or rate of change = -2 mi/h (the slope is negative, because distance remaining decreases as hours increases)

b = y-intercept = 13 miles (this is the total distance of the trail. x (hours) is zero at this point)

The equation of the given situation, in slope-intercept form would be:

\( y = -2x + 13 \)

A linear equation can be use to describe Jordan's distance because the

rate of change of the distance with time is constant.

Reasons:

From the map in the question, we have;

The distance of the trail Jordan has to hike = 13 miles

The rate at which Jordan will work = 2 mi/hr.

Part One:

Required:

The linear equation that represents the distance Jordan still has to walk

after x hours.

Solution:

Let y represent the distance Jordan still has to walk after x hours

The distance walked per hour = 2 miles

The distance walked after x hours = x × 2 miles = 2·x miles

Total distance = 13 miles

Distance remaining = Total distance - Distance walked

Distance remaining, y = 13 - 2·x

The linear equation that gives the distance Jordan still have to walk after x hours, is therefore;

y = 13 - 2·x

Second part:

The y-intercept is the y-value when x = 0

Therefore;

The y-intercept is; y = 13 - 2 × 0 = 13

Therefore;

The y-intercept represents the distance Jordan has to walk at the start

when the time, x, is 0, which is 13 miles or the the entire distance Jordan

has to walk.

To calculate the actual distance in km, we need to use the scale factor of 1:100 000. This means that 1 cm on the map is equivalent to 100 000 cm in real life.

Therefore, 12.3 cm on the map is equivalent to 12.3 x 100 000 cm in real life.

Now, 1 km is equivalent to 100 000 cm.

Therefore, 12.3 x 100 000 cm is equivalent to 1.23 km.

Hence, the actual distance in km is 1.23 km.

The domain of the function f(x) = -3x + 2 is (-∞, +∞), representing all real numbers, and the range is (-∞, 2], representing all real numbers less than or equal to 2.

The function f(x) = -3x + 2 is a linear function defined by a straight line. To determine the domain of this function, we need to identify the range of values for which the function is defined.

The domain of a linear function is typically all real numbers unless there are any restrictions. In this case, there is no explicit restriction mentioned, so we can assume that the function is defined for all real numbers.

Therefore, the domain of the function f(x) = -3x + 2 is (-∞, +∞), which represents all real numbers.

Now, let's analyze the range of the function. The range of a linear function can be determined by observing the slope of the line. In this case, the slope of the line is -3, which means that as x increases, the function values will decrease.

Since the slope is negative, the range of the function f(x) = -3x + 2 will be all real numbers less than or equal to the y-intercept, which is 2.

Therefore, the range of the function is (-∞, 2] since the function values cannot exceed 2.

Answer: See below

Step-by-step explanation:

The point-slope equation is y-y₁=m(x-x₁). Since we don't know our slope, we can use the formula \(m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\) to find the slope. All we have to do is use the coordinate we were given and plug it into the formula.

\(m=\frac{-1-(-3)}{2-(-3)} =\frac{2}{5}\)

Now that we have the slope, we can fill out the point-slope equation.

y-(-3)=2/5(x-(-3))

y+6=2/5(x+3)

This is the point-slope form.

Now, we can distribute and solve to get slope-intercept form.

y+6=2/5x+6/5

y=2/5x-24/5

To find the percent of wrong answers, follow the steps below.

Step 01: Find the fraction of correct/incorrect answers.

From the 4 portions, 3 represent the correct answers.

If the total of answers is 100%, then each portion represents 25% (1/4).

Then, the correct answer are:

The matrices matrix A be a 5 by 7 , matrix B be a 7 by 6 and matrix C be a 6 by 5 matrix.

now, we need to determine the size of the matrices

AB = \((AB)_{5*6}\)

BA is undefined

\(A^{T}\)B  is undefined

BC = \((BC)_{7*5}\)

ABC = \((ABC)_{5*5}\)

CA = \((CA)_{6*7}\)

\(B^{T}\)A is undefined.

B\(C^{T}\) is undefined.

given that

matrix A is \(A_{5*7}\)

matrix B is \(B_{7*6}\)

matrix C is \(C_{6*5}\)

now, we need to determine the size of the matrices

AB multiplication of two matrices

multiplication of two matrices is possible only when B has the same number of columns as rows in A,

\(A_{m*n}\)and \(B_{n*p}\)

If it is defined as above, then the matrix AB will have m rows and p columns, i.e., A must have n columns and B must have n rows in order for AB to be defined.

\((AB)_{m*n}\)

In addition, a matrix gets transposed when columns turn into rows and vice versa.

Thus, if

\(A_{m*n}\)⇒\((AT)_{m*n}\)

So, for this particular question, we have:  \(A_{5*7}\),  \(B_{7*6}\) , \(C_{6*5}\)

According to the aforementioned idea, AB is therefore \((AB)_{5*6}\) in size.

Additionally, BA and \(A^{T}\)B are not defined.

\((BC)_{7*5}\)

ABC=(AB)C=A(BC) because matrix multiplication is associative,

\((ABC)_{5*5}\)

\((CA)_{6*7}\)

\(B^{T}\)A is undefined. because they don't have same number of columns in matrix B and rows in matrix A

B\(C^{T}\) is undefined. because they don't have same number of columns in matrix B and rows in matrix C

Choice E and F

Step-by-step explanation:

acute = less than 90

Answer:

Step-by-step explanation:

Let the two-digit number be represented as $10a+b$, where $a$ is the tens digit and $b$ is the units digit. From the problem statement, we have:

$10a+b = 6(a+b)+7$ ....(1)

Also, we know that the tens digit is 3 more than the units digit, so we have:

$a = b+3$ ....(2)

Substituting (2) into (1), we get:

$10(b+3)+b = 6((b+3)+b)+7$

Simplifying the above equation, we get:

$11b+33 = 13b+25$

Subtracting $11b$ from both sides, we get:

$2b+33 = 25$

Subtracting 33 from both sides, we get:

$2b = -8$

Dividing both sides by 2, we get:

$b = -4$

Since $b$ represents a digit, we see that $b$ must be 6 (and not -4), since it is the only digit that satisfies the condition that the tens digit is 3 more than the units digit. Substituting $b=6$ into (2), we get:

$a = b+3 = 6+3 = 9$

Therefore, the two-digit number is $10a+b = 10(9)+6 = \boxed{96}$.
