Answer:
3t - 9Step-by-step explanation:
Given:
g(t) = t + 5 and h(t) = 3t - 2Find the composite function (g·h)(t):
(g·h)(t) = g(h(t)) = (3t - 2) + 5 = 3t + 3Find (g·h)(-4 + t):
(g·h)(-4 + t) = g(h(-4 + t)) = 3(-4 + t) + 3 = -12 + 3t + 3 = 3t - 9The given information is,
→ g(t) = t + 5
→ h(t) = 3t - 2
Now we have to,
find the composite function (g•h)(t),
→ (g•h)(t)
→ g(h(t))
→ (3t - 2) + 5
→ 3t + 3
Let's find the (g•h)(-4 + t):
→ (g•h)(-4 + t)
→ g(h(-4 + t))
→ 3(-4 + t) + 3
→ -12 + 3t + 3
→ 3t - 9
Hence, the value is 3t - 9.

Which type of parent function does the equation f(x) = va represent?
A. Cube root
B. Reciprocal
C. Square root
D. Absolute value
Answer:
reciprocal
Step-by-step explanation:
The function f(x) = √x is represented by the square root type of parent function.
What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
Given function is,
f(x) = √x
Here for any value of x, the function is mapped to √x.
That is, the function is mapped to the square root of the x.
Thus it is a square root function.
Hence the function is the square root function.

An airplane is flying in a direction of 165° with an airspeed of 650 mph. The wind is blowing at 50 mph in a direction of N 30° E. What is the ground speed and direction of the plane?
A) ground speed: 658 mph; direction 108°
B) ground speed: 639 mph; direction 161°
C) ground speed: 686 mph; direction 108°
D) ground speed: 698 mph; direction 161°
Answer:
B) Ground speed: 639 mph; direction 161°
Step-by-step explanation:
165° = 75° South of East = S15°E, therefore;
The component of the speed of the airplane are;
650 × cos(75°) East or x-direction in vector form:[tex]$650 \times \cos \left(75^{\circ}\right) \mathrm{i}$[/tex]
650 × sin(75°) South or negative y-direction in vector form: [tex]$-650 \times \sin \left(75^{\circ}\right) \mathrm{j}$[/tex]
The speed of the airplane is [tex]$650 \times \cos \left(75^{\circ}\right) \mathrm{i}-650 \times \sin \left(75^{\circ}\right) \mathrm{j}$[/tex]
The speed of the wind in vector form is 25i + 25·√3 j
The combined speed of the airplane and the wind is found as follows;
Combined: [tex]$\left(650 \times \cos \left(75^{\circ}\right)+25\right)\left[\dot{i}+\left(25 \cdot \sqrt{3}-650 \times \sin \left(75^{\circ}\right)\right) \mathrm{j}\right.$[/tex], which gives;
The resultant speed of the airplane, [tex]$\left.R=\sqrt{(} 193.23^{2}+(-584.55)^{2}\right)=615.66$[/tex]
The resultant speed of the airplane, [tex]$\mathrm{R}=615.66 \mathrm{mph}$[/tex]
The direction =[tex]$\arctan ((-584.55) /(193.23))=-71.7^{\circ}$[/tex]
The bearing [tex]$=90^{\circ}+71.7^{\circ}=162^{\circ}$[/tex]
Therefore, the closest option is option B, ground speed: 639 mph; direction 161°

https://brainly.com/question/18868816We're planning to enclose a rectangular field with fencing, and we know that for whatever reason we want the field to be 50 feet square. We also know that the field's width should be 23 feet longer than the field's length. What are the field's dimensions?
Answer:
[tex]? \times \frac{?}{?} [/tex]
d
Answer:
2 by 25 feet.
Step-by-step explanation:
Let L and W be the length and the widht of the field
we want W = L + 23 and W x L = 50
So
(L + 23) x L = 50
[tex]L^2 + 23L = 50\\L^2+23L-50 =0\\(L+25)(L-2)=0\\L=-25 \text{ or } L = 2[/tex]
Since L must be positive then L =2 and W = 2 + 23 = 25.

x + 3y = 7
3x + 4y = 11
Answer:
x = 1 y = 2
Step-by-step explanation:
x + 3y = 7
- Subtract x from both sides.
3y = -x + 7
- Divide both sides by 3 to isolate the variable.
y = -1/3x + 7/3
- Plug the value of y into the other equation.
3x + 4(-1/3x + 7/3) = 11
3x - 4/3x + 28/3 = 11
- Add like terms.
5/3x + 28/3 = 11
5/3x = 5/3
x = 1
- Plug the value of x into the equation.
x + 3y = 7
(1) + 3y = 7
3y = 6
y = 2

The histogram below shows the number of points scored by a high school basketball team over two seasons.
One player on the team wants to emphasize that his team generally scored a lot of points. Which measure of center should he report: the mean or the median?
a. He should report the mean.
b. He should report the median.
c. He could report either because they are equal.
d. The exact number of points per game are needed to decide.
To median should be reported in the to show th general measure of center since we have a skewed distribution.
The plot of the histogram Given is skewed to the right, hence it is positively skewed.
In a positively skewed distribution, the mean value of the distribution is always greater than the median. However, it does not give an accurate measure of center as much as the median does.
Therefore, if a player want to emphasize that his team generally scored a lot of points, then reporting the median would be best as it gives a better measure of center.
If the data was normally distributed, then the mean would be a better measure of center.
