\(40\% \times x = 10 \\\\\\\implies \dfrac{40}{100} x = 10\\\\\\\implies \dfrac{4x}{10} = 10\\\\\\\implies 4x = 100\\\\\implies x = \dfrac{100}4 =25\)
Answer:
x = 25
Step-by-step explanation:
40% of something = 10.
Let something = x
40% = 40 / 100
40/100 *x = 10 Multiply by 100
40x = 10 * 100 Combine
40x = 1000 Divide by 40
x = 1000/40
x = 25
Let P and Q be polynomials with positive leading coefficients. Consider the limit below. (If the limit is infinite, enter '[infinity]' or '-[infinity]', as appropriate. If the limit does not otherwise exist, enter DNE.) lim x→[infinity] P(x) Q(x) (a) Find the limit if the degree of P is less than the degree of Q. (b) Find the limit if the degree of P is greater than the degree of Q.
(a) If the degree of P is less than the degree of Q, the limit is 0. (b) If the degree of P is greater than the degree of Q, the limit is either [infinity] or -[infinity], depending on the leading coefficients.
(a) If the degree of polynomial P is less than the degree of polynomial Q, as x approaches infinity, the leading term of Q(x) dominates the expression. Since both P and Q have positive leading coefficients, the limit of P(x) / Q(x) as x approaches infinity is 0. The higher degree terms in Q grow faster, making the contribution from P negligible in comparison.
(b) If the degree of polynomial P is greater than the degree of polynomial Q, the limit of P(x) / Q(x) as x approaches infinity depends on the leading coefficients of P and Q. If the leading coefficients of both P and Q are positive, the limit will be [infinity]. If the leading coefficients have opposite signs, the limit will be -[infinity]. In both cases, the higher degree terms in P dominate the expression as x grows large.

Does it make sense to represent the number 15.3 using scientific notation yes or no?
Answer:
Not really. No.
Step-by-step explanation:
15.3 in scientific notation would be represented as "1.53e+1." 15.3 isn't a very large or tiny number. Usually numbers that would be represented by scientific notation would be numbers such as "600,000,000" or "0.00000012" etc. 15.3 is just a standard decimal so it's not really practical.

Angel X measures 42° find the measure of angle Y
Step 1
Use the law that the sum of angles on a straight line is 180° to find y given that x = 42°
Step 2
Using the law
x + y = 180°
After substitution
42 + y = 180
y = 180 - 42
y =138°
23. What lines intersect to form the circumcenter of a triangle?
angle bisectors
midsegments
altitudes
perpendicular bisectors
Answer:
(d) perpendicular bisectors
Step-by-step explanation:
The circumcenter is the center of the circumcircle of the triangle. Each vertex of the triangle lies on that circle. The sides of the triangle are chords of the circle.
The perpendicular bisector of a chord is a line that intersects the center of the circle containing the chord. Hence, the perpendicular bisectors of the sides of a triangle will intersect the circumcenter.
evaluate the triple integral. 16y dv, where e is bounded by the planes x = 0, y = 0, z = 0, and 2x 2y z = 4 e
The value of the triple integral is -16.
Triple integral is a mathematical concept used in calculus to calculate the volume of three-dimensional objects. It extends the concept of a single integral to functions of three variables and integrates over a region in three-dimensional space.
The triple integral of a function f(x, y, z) over a region E in three-dimensional space is denoted by:
∭E f(x, y, z) dV
We can set up the triple integral as follows:
∫∫∫ 16y dV
Where the limits of integration are:
0 ≤ x ≤ 2
0 ≤ y ≤ (2- \(x^2\)z)/(2y)
0 ≤ z ≤ 2/\(x^{2y\)
Note that the upper bound of integration for y is not a constant, but depends on both x and z.
Integrating with respect to y first, we get:
∫∫∫ 16y dV = ∫0^2 ∫\(0^(2-x^2z)/(2x)\)∫\(0^(2/x^2y) 16y dz dy dx\)
= ∫\(0^2\) ∫\(0^(2-x^2z)/(2x) 32/x dx dz\)
= ∫\(0^2\) [16(\(2-x^2z)/x^2\)] dz
= ∫\(0^2 (32/x^2 - 16z)\) dz
= 32∫\(0^2 x^-2 dx - 16\)∫\(0^2\)z dz
= 16 - 16(2)
= -16
Therefore, the value of the triple integral is -16.

Work Shown:
Plug in x = -5. Use PEMDAS to simplify
f(x) = |3x-2|
f(-5) = |3(-5)-2| ... replace every x with -5
f(-5) = |-15-2|
f(-5) = |-17|
f(-5) = 17
---------------------
Repeat for x = 7
f(x) = |3x-2|
f(7) = |3*7-2| ... replace every x with 7
f(7) = |21-2|
f(7) = |19|

Find the exact value of sec(theta) if cot(theta)= -1/2 and the terminal side of theta lies in quadrant ii.
a. sec(theta)= -sqrt(5)/2
b. sec(theta)= sqrt(t)/2
c. sec(theta)= -sqrt(5)
d. sec(theta)= sqrt(5)
Using trigonometric identities, it is found that the exact value of the secant of the angle is given by:
c. \(\sec{\theta} = - \sqrt{5}\)
How is the tangent related to the secant?According to the following identity:
\(\sec^2{\theta} = 1 + \tan^2{\theta}\)
The tangent is the inverse of the cotangent, hence in this problem, we have that:
\(\tan{\theta} = -2\)
Then, the secant is given as follows:
\(\sec^2{\theta} = 1 + (-2)^2\)
\(\sec^2{\theta} = 5\)
\(\sec{\theta} = \pm \sqrt{5}\)
The angle is in the second quadrant, where the cosine is negative, hence the secant also is and option c is correct, that is:
c. \(\sec{\theta} = - \sqrt{5}\)

The cost of a school banquet is $90 for the room rental and $14 per person attending. Write an expression to model the total cost of the banquet for p people. What is the cost for 70 people?
Answer:
Total Cost (p) = 90 + 14p
For 70 people = $1070
Step-by-step explanation:
Let p stand for the number of people attending the banquet
Fixed cost = $90
Variable cost = $14p
Total Cost (p) = 90 + 14p
=================
Cost for 70 people (p=70)
Total Cost = $90 + $14(70)

Step-by-step explanation:
This is the case of a isosceles triangle , as you may know in a isosceles triangle , there are two sides of equal length as well as two equal angles.
You know that the sum of angles in a triangle is 180°, therefore it comes to this equation :
15° + 2x = 180°
2x = 165°
x = 82.5°
therefore 82.5° is the correct answer.

Step-by-step explanation:
6.83 x 10¹ is 68.3, 9.1 x 10¹ is 91, 68.3 - 91 is 22.7
Answer:
6739/100
Step-by-step explanation:
heres how i got that answer
first step
any expression raised to the power of 1 equals its self. remove unnecessary parentheses
(6.83 x 10) - 9.1 x 10^-1
second step
6.83 x 10 = 68.3 then make the other decimal into a fraction so 91 over 10 or 91/10 any expression raised to the power of - 1 equals its reciprocal so now you have
68.3 - 91/10 x 1/10
third step
convert the decimal into a fraction 683/10
then multiple 91/10 and 1/10 to get 91/100
so now you should have 683/10 - 91/100
last step
subtract the fractions giving you

to do the survey
Systematic sampling offers several advantages. It is relatively easy to implement and eliminates bias that may arise from the subjective selection of participants.
The sampling method described in the scenario is called systematic sampling.
Systematic sampling involves selecting every nth element from a population after randomly selecting a starting point. In this case, the store manager randomly chooses a shopper entering the store as the starting point and then proceeds to interview every 20th person after that initial selection.
Systematic sampling offers several advantages. It is relatively easy to implement and eliminates bias that may arise from the subjective selection of participants. By ensuring a regular interval between selections, systematic sampling provides a representative sample from the population.
However, it's important to note that systematic sampling can introduce a form of bias if there is any periodicity or pattern in the population. For example, if the store experiences a peak in customer traffic during specific time periods, the systematic sampling method might overrepresent or underrepresent certain groups of shoppers.
To minimize this potential bias, the store manager could randomly select the starting point for the systematic sampling at different times of the day or on different days of the week. This would help ensure a more representative sample and reduce the impact of any inherent patterns or periodicities in customer behavior.

Re-write the quadratic function below in standard form.
y= -9(x-1)²-6
To rewrite the quadratic function y = -9(x-1)²-6 in standard form, we need to expand the squared term and simplify the expression. Here are the steps:
Distribute the negative sign to the squared term: y = -9(x² - 2x + 1) - 6
Multiply -9 by each term inside the parentheses: y = -9x² + 18x - 9 - 6
Combine the constants: y = -9x² + 18x - 15
Therefore, the standard form of the quadratic function y = -9(x-1)²-6 is y = -9x² + 18x - 15.
