g(t) = -2t + 3f(t) = 2t - 5
Find (g f)(t)

Answers

Answer 1

Answer:

( g − f ) ( a ) = g ( a ) − f ( a )

( g −f ) ( a ) = g ( a ) − f ( a )

= − 3 a − 3 − a 2 − 5

= − a 2 − 3a − 8

Step-by-step explanation:

Answer 2

After calculating, the value of (g f) (t) is ( - 4t + 13).

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The functions are,

⇒ g(t) = -2t + 3 and f (t) = 2t - 5

So, The value of function (g f) (t) is find as;

⇒ (g f) (t) = g (f (t))

= g (2t - 5)

= - 2 (2t - 5) + 3

= - 4t + 10 + 3

= - 4t + 13

3x + 7 = -8
Help me!

Answers

Answer: x=-5

First, subtract 7 from both sides.
That equals -15.
Then, you have “3x=-15”
All you do TJEM is divide -15 from 3x, which equals -5

Your goal is to have x by itself so
3x + 7 = -8
Subtract 7 by both side leave you with
3x = -15
Then you divide 3 both side leave you with
X = -5
The answer is x = -5

For every 15 students who run track, there are 7 students who play baseball. There are 112 more students who run track than play baseball. How many students run track? How many students play baseball? Select your answers from the drop-down lists.

Answers

Answer:

210 students run track and 98 students play baseball

Step-by-step explanation:

For every 15 students who run track there are 7 students who play baseball

There are 112 more students who run track than play baseball

Let y represent the various groups of students

15 × y= 15y

7 × y= 7y

15y - 7y = 112

8y = 112

Divide both side by the coefficient of y which is 8

8y/8 = 112/8

y= 14

Therefore the number of students that run track is

= 15 × 14

= 210

The number of student that play baseball is

= 7 × 14

= 98

Hence 210 students run track and 98 students play baseball

A half-marathon is 13.1 miles long. There is a water station every 1 1/3 miles along the race trail and at the finish line. How many water stations are needed for the half-marathon?
choices
15
13
10
11

Answers

Answer:

10 water stations are needed

Step-by-step explanation:

To get the number of water- station needed, we simply divide the total length of the half marathon by the distance where we can find a water station

mathematically,

that would be 13.1 divided by 1 1/3

= 13.1 divided by 4/3

= 13.1 * 3/4 = 9.825 which is approximately 10

What is true about the angles and side lengths of parallelogram QTSR?
Enter the correct answers in the boxes

Answers

Answer:

[tex]\huge\boxed{Q = 110 \textdegree, \ ST = 9 \ \text{ft}}[/tex]

Step-by-step explanation:

When we reflect and transform a figure, the angle lengths nor the side lengths are touched. The side length only changes if we dilate or stretch the figure, and the angle length only changes if we stretch the figure.

Therefore, we know the information is going to be the exact same. We just have to figure out what corresponds to what from JKLM to QTSR.

If we reflect a figure across a horizontal reflection line through its center, the figure will just flip sides. M will be J, L will be K, etc.

When we translate this down, nothing changes except its position. So we can pretend these two shapes are right on top of each other for now.

When we move these right on top of each other, we can see that Angle J overlaps with Angle Q. Since they don't have any weird intersects, we know that angle J will be equal to Angle Q. Since we already know J is 110°, we know Q is also 110°.

When we move it on top, we also see that KL overlaps with ST perfectly. Since we know KL is 9, that must mean ST is also 9.

The time, in seconds, that it takes a pendulum to swing back and forth is modeled by the equation below. f (l) = 2 pi StartRoot StartFraction l Over 32 EndFraction EndRoot, where l is the length of the pendulum in feet What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?

Answers

Answer:

46.08 feet.

Step-by-step explanation:

Given that, for length, [tex]l[/tex] feet, the time period, [tex]f(l)[/tex], of the pendulum is

[tex]f(l)=2\pi\sqrt{\frac{l}{32}}[/tex].

As the time period equals the time taken by the pendulum in one back and forth motion, so, actually, the given [tex]2.4\pi[/tex] seconds to swing back and forth is the time period.

Let [tex]l_0[/tex] feet be the length of the pendulum for the time period [tex]2.4\pi[/tex] seconds, so

[tex]f(l_0)=2.4\pi[/tex]

[tex]\Rightarrow 2\pi\sqrt{\frac{l_0}{32}}=2.4\pi[/tex]

[tex]\Rightarrow \sqrt{\frac{l_)}{32}}=1.2[/tex]

[tex]\Rightarrow \frac{l_0}{32}=(1.2)^2[/tex] [squaring on both the sides]

[tex]\Rightarrow l_0=1.44\times32[/tex]

[tex]\Rightarrow l_0=46.08[/tex]

Hence, the approximate length of a pendulum that takes [tex]2.4 \pi[/tex] seconds to swing back and forth is 46.08 feet.

A plane flies 455 miles with the wind in the same time that it takes to fly 400 miles against the wind. If the wind is blowing at a speed of 12mph, whats the speed of the plane in still ai

Answers

Answer:

186.55 mph

Step-by-step explanation:

Let the speed of the plane be s

The speed of the plane in the same direction is

s + 12

The speed of the plane against wind is

s - 12

Time = distance/speed

455/(s + 12) = 400/(s - 12)

Solving for s

400(s + 12) = 455(s - 12)400s + 400*12 = 455s - 455*12455s - 400s = (400 + 455)*1255s = 10260s = 10260/55s = 186.55 mph
