Step-by-step explanation:

(3h - 5)(5h + 4) =   3h * 5h    +   3h * 4     - 5*5h    - 5 *4

                              =    15h^2        - 13h    -20

\((3h-5)(5h+4)\)

\(=(3h+-5)(5h+4)\)

\(=(3h)(5h)+(3h)(4)+(-5)(5h)+(-5)(4)\)

\(=15h^2+12h-25h-20\)

Answer:

Answer:

The answer is D: 130

Step-by-step explanation:

(3x-28) +90+(66-x) = 180

2x + 128 = 180

2x = 52

x = 26

Therefore Angle AOE = 90 + (66-26)

= 130

The function is continuous in the domain x ≥ 3/4

Here we have a root function:

f(x) = ⁴√(4x - 3)

This is an even degree root function, so we have problems when the argument is negative.

Then the allowed values (where the function is defined, and thus, continuous) are:

4x - 3 ≥ 0

4x ≥ 3

x ≥ 3/4

There the function is continuous.

Answer:

10.31 ft

Step-by-step explanation:

the base is 25 ft²

leaves 100 ft² for the 4 sides on top

so each triangle got 25ft²

the base length of the triangle is 5ft, bc it's the base length of the pyramid

so the height of the triangle is 10ft,

bc only then do we get a surface area of 25ft²

(b * h /2) for the triangle

now that we got base length and height,

let's look for the slant

we recall the pythagoras stuff to get the missing side of the triangle. but notice that we need to split the triangle in half to get a 90° angle.

leaving us with 10ft (height) and 2.5ft

slant² = 10² + 2.5²

slant² = 106.25

slant = sqrt(106.25)

slant = 10.31

Answer:

70%

Step-by-step explanation:

the ratio is 14 to 6 so if you have 14 small milkshakes you would also have 6 regular milkshakes

to find a percentage we can buff up the ratio to add up to 100

14 + 6 = 20

100 / 20 = 5

that means we must multiply each side by 5

14 * 5 = 70

6 * 5 = 30

the ratio is now 70 to 30

you would have 70% of milkshakes that are small

By using the given table, we will get the linear equation:

h = n - 9

We know that they always get comic books together, so always that Nisha's collection increases by one, Hakim's collection will also increase by one, so we will have a linear equation.

Now, if you look at the given table, you can see that Hakim's collection is always 9 units less than Nisha's collection, then the linear equation that models the relation between the two collections, h and n, is really straightforward, it will be:

Hakim's collection = Nisha's collection - 9

Using the variables, we get:

h = n - 9

That is the linear equation Hakim wanted.

A prism is a solid shape that is bound on all its sides by plane faces. prism is named after the shape of these bases.

The base of this prism is rectangular. The volume of a prism is expressed as;

V = base area × height

base area = 7 × 10 = 70cm²

height = 7cm

the volume of the shape = 70× 7 = 490cm²

3. The factored polynomial is p(x) = (x - 1)(x - 5)

4. The factored polynomial is p(x) = (x + 3)²

A polynomial is a mathematical expression in which the power of the unknown is greater than or equal to 2.

3. To factorize the polynomial using the graph, we see that the polynomial cuts the x - axis at x = 1 and x = 5.

This implies that its factors are (x - 1) and (x - 5)

So, the factored polynomial is p(x) = (x - 1)(x - 5)

4. To factorize the polynomial using the graph, we see that the polynomial touches the x - axis at only one point x = -3. So,it has repeated roots

This implies that its factors are (x - (-3)) = (x + 3) twice

So, the factored polynomial is p(x) = (x + 3)²

Answer:

(a) \(y = 0.025x+15\)

(b) 18.5 minutes

(c) 450.4 minutes

Step-by-step explanation:

Given

\(290\ minutes = \$22.25\)

\(360\ minutes = \$24.00\)

Solving (a): Determine the linear equation

First, we need to calculate the slope (m)

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Where

\((x_1,y_1) = (290,22.25)\)

\((x_2,y_2) = (360,24.00)\)

So, we have:

\(m = \frac{24.00 - 22.25}{360 - 290}\)

\(m = \frac{1.75}{70}\)

Multiply through by 100

\(m = \frac{1.75 * 100}{70 * 100}\)

\(m = \frac{175}{7000}\)

Next, is to calculate the equation of the line using:

\(y - y_1 = m(x - x_1)\)

Recall that:

\((x_1,y_1) = (290,22.25)\)

\(m = \frac{175}{7000}\)

\(y - 22.25 = \frac{175}{7000}(x - 290)\)

\(y - 22.25 = \frac{175x}{7000} - \frac{175}{7000} * 290\)

\(y - 22.25 = \frac{175x}{7000} - \frac{50750}{7000}\)

Add 22.25 to both sides

\(y = \frac{175x}{7000} - \frac{5075}{700} + 22.25\)

\(y = \frac{175x}{7000} + \frac{-5075 + 15575}{700}\)

\(y = \frac{175x}{7000} + \frac{10500}{700}\)

\(y = 0.025x+15\)

(b) Solve for y when x = 140

\(y = 0.025x+15\)

Substitute 140 for x

\(y = 0.025 * 140 + 15\)

\(y = 3.5 + 15\)

\(y = 18.5\)

(c) Solve for x when y = 26.25

\(y = 0.025x+15\)

Substitute 26.25 for y

\(26.25 = 0.025x + 15\)

Solve for 0.025x

\(0.025x = 26.26 - 15\)

\(0.025x = 11.26\)

Solve for x

\(x = 11.26/0.025\)

\(x = 450.4\ minutes\)

The equation of the line in vector and parametric form is found to be R = -i+j-4k + λ(-3j-2k) and x+1/0 = y-1/-3 = z+4/-2 = t.

The line pass through the point P (-1,1,-4) and parallel to the vector (0, -3, -2).

Now, the vector form of the line is given by,

R = A+λB

Where, A is the point from which line pass, B is the parallel vector and λ is the scalar.

Putting values,

R = -i+j-4k + λ(-3j-2k)

Now, the parametric form of the equation will be,

x-a/m = y-b/n = z-c/l

Where, m, n, l are the direction ratios of the line that are equal to the vector that is parallel and a, b, c are the direction cosines of the line that are the point through which the line passes. So,

x+1/0 = y-1/-3 = z+4/-2 = t

Where t is any parameter.

So, the vector and parametric form of the equation of line are R = -i+j-4k + λ(-3j-2k) and x+1/0 = y-1/-3 = z+4/-2 respectively.

Answer: Suppose there exists a positive rational number r such that r^2 < 2. Then we have 2 - r^2 > 0. Let h = (2 - r^2)/4. Then h > 0 because r^2 < 2.

Consider the number rh = r + h. We have:

(rh)^2 = (r + h)^2 = r^2 + 2rh + h^2 = r^2 + 2(2 - r^2)/2 + (2 - r^2)/16

= r^2 + 2 + (2 - r^2)/16

< 2 + 2 + (2 - 2)/16 = 2.

Thus, for any positive rational number r such that r^2 < 2, there exists a larger positive rational number rh = r + h such that (rh)^2 < 2.

A Venn diagram is a visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects.

Circles that overlap share certain characteristics, whereas circles that do not overlap do not.

Venn diagrams are useful for showing how two concepts are related and different visually.

When two or more objects have overlapping attributes, a Venn diagram offers a simple way to illustrate the relationships between them.

Venn diagrams are frequently used in reports and presentations because they make it simpler to visualize data.

Answer:

Tahlia was correct in remembering that you can find the slope of a line using the slope formula.

She was also correct that the slope is 0.5.

However, if you use the slope-intercept formula y = mx + b, you still have to find b (the y-intercept) by plugging in one of the two points and the slope.

So, if we plug in the first point and the slope into the line, we can find b and thus the full equation of the line:

1. Gender - qualitative

2. Age - Quantitative (Discrete)

3. Grade point Average - quantitative (Continuous )

4. Number of courses currently enrolled - quantitative (discreet)

5. Enrollment Status - qualitative

Step-by-step explanation:

Qualitative variables are those which are non-numeric, usually made up of strings or words. The quantitative variables are numeric, usually composed of digits and numbers.

Discreet variables have a finite or limited number of values which are countable as opposed to continuous variables with a non-finite range and hence, uncountable.

Gender is a qualitative variable as it is composed of non-nemeric labels which could be either Male or Female.

Age - is numeric and hence quantitative, since age is usually expressed in years, hence it is discreet.

Grade point Average is a quantitative and continuous variable due to its numeric nature and the fact that it can take up an infinite number of possible values including decimal values.

Number of courses enrolled is numeric can take a finite number of values, hence, it is discreet.

Enrollment status is qualitative as it is split into :
