g(d) = 2d - 5
h(d) = -4d +3
Find (hºg)(d)
Answer:
[tex](h\circ g)(d)=-8d +23[/tex]
Step-by-step explanation:
Composite Function
Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:
[tex](h\circ g)(d)=h(g(x))[/tex]
For practical purposes, it can be found by substituting g into h.
The functions g and h are given as:
[tex]g(d) = 2d - 5[/tex]
[tex]h(d) = -4d +3[/tex]
Substituting g into h:
[tex](h\circ g)(d)=-4(2d - 5) +3[/tex]
Operating:
[tex](h\circ g)(d)=-8d +20 +3[/tex]
[tex]\boxed{(h\circ g)(d)=-8d +23}[/tex]

Brady noticed that there were 38 cars in the parking lot. 7 of the cars were blue.
What decimal represents the percent of the cars that were blue? Round your answer to the nearest hundredth.??????!!!! Help! :)
Answer:
Step-by-step explanation:
7 blue cars out of 38 cars.
To find the percentage you just divide using your calculator and you should get something like this :
[tex]\frac{7}{38}[/tex] = 0.1842105263
Then you just round that to the nearest hundredth.
If you round 0.184 to the nearest hundredth, it will be 0.18 (You have to round down since the number 4 in the thousandth place is smaller than 5)
1. In the diagram below, if m angle1=79^ , find the measure of each numbered angle.
The measure of angles ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.
We have been given that m angle ∠1 = 79°,
To determine the measure of each numbered angle.
As per the property supplementary angles,
m∠1 + m ∠2 = 180°
79° + m ∠2 = 180°
m ∠2 = 180° - 79°
m ∠2 = 101°
If a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
∠1 = ∠4 = 79°
∠2 = ∠3 = 101°
∠2 = ∠6 = 101°
∠4 = ∠5 = 79°
∠5 = ∠8 = 79°
∠6 = ∠7 = 101°
Thus, the measure of angles ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.

Answer: you have: C(X)=3x+2.00
x=number of minutes
Pay attention to the y=mx+b form where m=slope-->>
3x is the slope...
so it's 3(times the number of minutes) <<---or (x)
This means that the slope is 3, or the fancy way of saying it-->>"rate of change."

The amount of money and dollars that it cost to purchase x square feet of the carpet is given by f(x)= 8x the insulation feet is $125 more than 8% of the cost of the carpet right function of g that represents the insulation fee then use the function to find the insulation fee for 175 square feet of carpet
Answer:
The insulation fee for 175 square feet of carpet is $237.
Step-by-step explanation:
The amount of money, f(x), that it cost to purchase x square feet of the carpet is:
f(x)= 8x
The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have
g(x)=8% of f(x)+125
[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]
[tex]\Rightarrow=0.64x+125[/tex]
The insulation fee for 175 square feet of carpet,
i.e for x=175
[tex]g(x=175)=0.64\times175+125=237[/tex]
Hence, the insulation fee for 175 square feet of carpet is $237.

Answer:
c = 30°
d = 60°
Step-by-step explanation:
Angle ZWC is a 90° angle
Angle YWX is a 60° angle
add them together and you get 150°
180 - 150 = c = 30°
c + d + 90° = 180°
substitute
30° + d + 90° = 180°
combine like terms
120° + d = 180°
subtract 120° from both sides
d = 60°
