The functions q and r are defined as follows.
q(x)=2x + 2
r(x)=-2x²-2
Find the value of r(q(2)).
Answers
Answer:
Step-by-step explanation:
[tex]r(x)=-2x^2-2\\ \\ q(x)=2x+2\\ \\ r(q(x))=-2(2x+2)^2-2\\ \\ r(q(2))=-2(2(2)+2)^2-2\\ \\ r(q(2))=-2(6^2)-2\\ \\ r(q(2))=-2(36)-2\\ \\ r(q(2))=-72-2\\ \\ r(q(2))=-74[/tex]

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3x = 4 is an expression.
3x + 4x - 4 is an expression.
We have,
The sum of the measures of angle P and angle S is 140°.
The measure in degrees of angle P is represented by the expression.
= (5x + 30)
The measure of angle S.
= 80°
Now,
5x + 30 + 80 = 140
5x + 110 = 140
Subtract 110 on both sides.
5x = 140 - 110
5x = 30
Divide both sides by 5.
x = 6
Thus,
The value of x is 6.

Step-by-step explanation:
110 ft = circumference (C)
C=2r
110=2r
110/2=2r/2
55=r
Area of a circle (A) = πr²
Use 3.14 for π

Answer:
Step-by-step explanation:
First we must distribute the multiplier 3 over x + 4, obtaining 3x + 12.
We then have 3x + 12 = 3x + 12, or 12 = 12. This is always true; the given equation has an infinite number of solutions.

9. Bianca is hosting a dinner party for 10 people. The main course's recipe states
that 400 g of sausage and 500 g of dry pasta is enough for four people.
a) How much sausage will she need?
b) How much pasta will she need?
Answers
Answer:
a) 1000 grams
b) 1250 grams
Step-by-step explanation:
Find out how much grams of sausage and dry pasta she needs for each person.
4 people = 400 g
1 person = 400 ÷ 4 = 100 g (sausage)
4 people = 500 g
1 person = 500 ÷ 4 = 125 g (dry pasta)
Find out how much grams of sausage and dry pasta is needed for 10 people.
10 person = 100 x 10 = 1000g (sausage)
10 person = 125 x 10 = 1250g (dry pasta)
Parking at a large university has become a very big problem. University administrators are interested in determining the average parking time (e.g. the time it takes a student to find a parking spot) of its students. An administrator inconspicuously followed 250 students and carefully recorded their parking times. The university is interested in using the information from the sample of 250 students collected to learn information about the entire student parking population. Would this be an application of descriptive or inferential statistics
Answers
Answer:
Inferential statistic
Step-by-step explanation:
The art of making deductions or data driven predictions from statistical data refers to an aspect of statistics called Inferential statistics. Inferential statistics differs from descriptive statistics which is another aspect which focuses on presenting characteristics of data. Here, we make statistical deductions about the entire population from the results obtained about the sample statistic. In the scenario above, the statistic derived from the sample data will be used to make deductions about the general population of students who park in the university. Therefore, from the statistic obstaied from the sample, we infer about the population.

Type of quadrilateral are:
Trapezoid.Rectangle.Parallelogram.Rhombus.Square.Kite.A figure has vertices A = (0, 0), B = (1, 3), C = (0, 4), and D = (-1, 1).
The distance between AB is given as,
AB = √[(1 - 0)² + (3 - 0)²]
AB = √10 units
The distance between AD is given as,
AD = √[(-1 - 0)² + (1 - 0)²]
AD = √2 units
The measure of the adjacent sides is not equal. Then the MOST precise classification for figure ABCD will be a parallelogram.

Three girls share R12000 in the ratio 2:3: 7. Calculate how much each girl
will get
Answers
2+3+7=12
12=12000
2?=
2×12000=24000÷12=2000.
R2000 for the first girl.
Step-by-step explanation:
3×12000=36000÷12=3000.
R3000 for the second girl.
7×12000=84000÷12=7000.
R7000 for the third girl.
Each of the three girls would get R2,000, R3,000 and R7,000 respectively.
Given the following data:
Total amount = R12,000.Ratio = 2:3:7Sum of ratio = [tex]2+3+7[/tex] = 12.To share R12,000 among three girls in the ratio of 2:3:7:
How to calculate a ratio.In this exercise, you're required to share the total amount of money among three girls in the ratio of 2:3:7. Thus, we would solve as follows:
For a ratio of 2:
[tex]Amount=\frac{2}{12} \times 12000\\\\Amount=\frac{24000}{12}[/tex]
Amount = R2,000.
For a ratio of 3:
[tex]Amount=\frac{3}{12} \times 12000\\\\Amount=\frac{36000}{12}[/tex]
Amount = R3,000.
For a ratio of 7:
[tex]Amount=\frac{7}{12} \times 12000\\\\Amount=\frac{84000}{12}[/tex]
Amount = R7,000.
