A car leaving a stop sign accelerates constantly from a speed of 0 feet per second to reach a speed of 44 feet per second. The distance of the car from the stop sign, d d , in feet, at time t t , in seconds, can be found using the equation d=1.1t2 d = 1 . 1 t 2 . What is the average speed of the car, in feet per second, between t=2 t = 2 and t=5 t = 5 ?

Answers

Answer 1

Answer:

c

Step-by-step explanation:

The distance of the car from the stop sign, d , in feet, at time t , in seconds, can be found using the equation

The average rate of change of a function f(x) on [a,b] is

We need to find the average speed of the car, in feet per second, between t=2 and t=5.

At t=2,

At t=5,

The average speed of the car, in feet per second, between t=2 and t=5 is

The average speed of the car, in feet per second, between t=2 and t=5 is 7.7 feet per second.

The equation of a line is y = 2x − 6. Find the slope and y-intercept of the line.

Answers

Answer:

Slope is 2 and y-int is -6

Step-by-step explanation:

y=mx+b

M is slope

B is y-int

Answer:

The slope is 2 and the y intercept would be -6

Step-by-step explanation:

y=mx+b where M would be the slope and b is the y intercept. Fill in the formula and there you have the slope and the y intercept. Good luck!

Terrell wrote that 5 – 4.2 = 8. Which statement about his answer is true? CLEAR CHECK 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it. 8 is right because 50 – 42 = 8. 8 is right because 4.2 + 8 = 5. 8 is wrong because you cannot subtract a decimal from a whole number.

Answers

Answer:

a) is wrong because a number gets smaller, not larger, when you take 4.2 from it

Step-by-step explanation:

Given

[tex]5 - 4.2 = 8[/tex]

Required

Determine which of the options is true

First, we need to solve for 5 - 4.2

[tex]5 - 4.2 = 0.8[/tex]

Compare this answer with Terell's answer (8)

We observe that: [tex]0.8 \neq 8[/tex]

This implies that; Terell is wrong

The two options that support the answer being wrong are (a) & (d)

Analyzing (a):

5 should get smaller when 4.2 is subtracted from it.

This isn't the case in Terell's solution.

Hence, (a) is true

Analyzing (d):

d is wrong because a decimal can be subtracted from a whole number

Hence, (a) answers the question

Joseph needs 345 cement blocks to build a wall 40 cm thick. He needs 205 cement blocks to build a wall 25 cm thick. Each block costs $0.75. How much more will the thicker wall cost?

Answers

9514 1404 393

Answer:

  $105

Step-by-step explanation:

The thicker wall takes 345 -205 = 140 more blocks. Each of those costs $0.75, so the added blocks will cost ...

  140 × $0.75 = $105

The thicker wall will cost $105 more.

A new video game is expected to sell 120 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 15(x - 1) where x is the number of hours. What is the
function that shows total sales, including the first hour? (1 point)
s(x) = 15(x - 1) - 120
s(x) = 120x - 15
Os(x) = 120 + 15(x - 1)
Os(x) = 120 - 15(x - 1)

Answers

Answer:

X=104

Step-by-step:

Sorry IF my answer is wrong

Answer:

Os(x) = 120 + 15(x - 1)

Step-by-step explanation:

The total sales will be the sum of the constant 120 copies that were sold in the first hour and the sales in the subsequent hours, represented by the function s(x) = 15(x-1).

Thus, add 120 to the function s(x).

What is the slope of a line that is perpendicular to the graphed line?

Answers

Answer:

The slope of the line perpendicular to the graphed line is 2.

Step-by-step explanation:

The Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The graphed line passes through two visible points (0,4) and (8,0). Thus, its slope is:

[tex]\displaystyle m=\frac{0-4}{8-0}[/tex]

[tex]\displaystyle m=\frac{-4}{8}[/tex]

Simplifying:

[tex]\displaystyle m=-\frac{1}{2}[/tex]

Two lines of slopes m1 and m2 are perpendicular is:

[tex]m_1.m_2=-1[/tex]

Suposse the given line has slope [tex]m_1=-\frac{1}{2}[/tex]. To find m2, we solve the above equation:

[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]

Substituting:

[tex]\displaystyle m_2=-\frac{1}{-\frac{1}{2}}[/tex]

Operating

[tex]m_2=2[/tex]

The slope of the line perpendicular to the graphed line is 2.

If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?

Answers

Answer:

3miles per hour^2

Step-by-step explanation:

given data

initial speed u= 15mph

final speed v=45mph

time taken t= 10 seconds

Step two:

Required

acceleration a=?

applying the first equation of motion

v=u+at

substitute we have

45=15+a*10

45=15+10a

make a subject of the formula

45-15=10a

30=10a

divide both sides  by 10

a=30/10

a=3miles per hour^2

3x + 4y = 36
(3,-2)
(1,7)
(0,0)
(24,-9)
(0,9)
(4,6)
(-12,18)

Answers

Answer: (24,-9)

(0,9)

(4,6)

Step-by-step explanation:

3x + 4y = 36

Using (3,-2) will be:

= 3(3) + 4(-2)

= 9 - 8 = 1

Using (1,7) will be

= 3(1) + 4(7)

= 3 + 28 = 31

Using (0,0) equals to 0

Using (24,-9) will be:

= 3(24) +4( -9)

= 72 - 36 = 36

Using (0,9) will be:

= 3(0) + 4(9)

= 0 + 36 = 36

Using (4,6) will be:

3(4) + 4(6)

= 12 + 24

= 36

Using (-12,18) will be:

= 3(-12) + 4(-18)

= -36 - 72

= -108

The correct options are (24,-9), (0,9 and (4,6)
