Please help in the next ten minutes

Answers

Answer 1

Answer: 8 - 2x = 5
- 2x = 5 - 8
- 2x = - 3 .(-1)
2x = 3
x = 3 = 1.5

rachel is a stunt driver. One time during a gig where she escaped from a building about to explode she drove to get to the safe zone at 24 meters per second. After 4 seconds of driving she was 70 meters away from the safe zone. Let D(t) denote the distance to the safe zone D (measured in meters) as a function of time t (measured in seconds) writ the functions formula

Answers

The distance from the safe zone after t seconds is $\rm D(t) = 166 - 24 t$ .

Given

Rachel is a stunt driver.

One time during a gig where she escaped from a building about to explode she drove to get to the safe zone at 24 meters per second.

After 4 seconds of driving, she was 70 meters away from the safezone.

What is a linear function?

A linear function containing one dependent and one independent variable.

It is represented in the form of;

$\rm y =mx+c$

Where m is the slope.

Let, D(t) = the distance to the safe zone (measured in meters)

t = time (measured in seconds)

At seconds t = 4 seconds D(t1) = 70 meters

Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.

Hence, the linear function expression is;

$\rm D(t) = -24t+b$

The value of b is;

$\rm D(t_1) = -24t+b\n\n70 = -24* 4+b\n\n70=-96+b\n\nb = 96+70\n\nb=166$

Therefore, the distance from the safe zone after t seconds is $\rm D(t) = 166 - 24 t$ .

Answer: The required function is,

D(t) = 166 - 4 t

Step-by-step explanation:

Here, the speed of the stunt driver = 24 meters per seconds,

⇒ The distance he will cover in 4 seconds = 24 × 4 = 96 meters

( Distance = speed × time )

According to the question,

The distance of the safe zone from the building where did he escape = 70 meters + The distance he covers in 4 seconds

= 70 + 96

= 166 meters

Hence, if he is driving with the constant speed of 24 meters per minutes,

Then, his distance from the safe zone after t seconds = 166 - 24 t

⇒ D(t) = 166 - 24 t

Which is the required function.

Solve this problem.Brianna paid $18.89 for a pair of sandals. She bought a pair of hiking boots that cost $12 more than her sandals. How much did Brianna pay for the two pairs of shoes?

How can estimation be used to make sure the answer is reasonable?

A.
Answer: Brianna paid $42.89.
Estimation: $19 + $12 = $31
$31 + $12 = $43
Brianna paid about $43 for the shoes.

B.
Answer: Brianna paid $25.78.
Estimation: $19 – $12 = $7
$19 + $7 = $26
Brianna paid about $26 for the shoes.

C.
Answer: Brianna paid $49.78.
Estimation: $19 + $12 = $31
$31 + $19 = $50
Brianna paid about $50 for the shoes.
