The acceleration of the car is = 3m/s/s. The calculation of the acceleration is further described below.

<h3>What is acceleration?</h3>

Acceleration can be defined as the rate at which the velocity of a moving object changes with respect to time.

a = V2 - V1/t

where V1 ( Initial velocity)= 0m/s

V2 (final velocity)= 45 m/s

t( time ) = 15 secs

a = 45-0/15

a = 45/15

a = 3m/s/s

Therefore, the acceleration of the car is = 3m/s/s

Answer:

Step-by-step explanation:

To find the inverse function switch variables out and solve for y

y=(x+3)/x swap variables to get

(y+3)/y=x then solve for y

y+3=yx

y-yx+3=0

y-yx=-3

y(1-x)=-3

y=-3/(1-x)

y=3/(x-1)

What is the value of x in the equation 2(x+3) = 4(x-1)?<br> own

11111nata11111 [884]

Step-by-step explanation:

Solving

2x + 6 = 4x - 4

Bringing like terms on one side

6 + 4 = 4x - 2x

10 = 2x

10 / 2 = x

5 = x

This net can be folded to make a square pyramid. what is the surface area of the pyramid

givi [52]

Answer:

$85in^2$

Step-by-step explanation:

to find the surface area we need to find the followng areas:

area of the square

area of a triangle and multiply it by 4 (because there are 4 triangles)

And once we have those areas, we add them to find the surface area.

Area of the square:

the formula to find the area of a square is:

$a_{square}=l^2$

where $l$ is the length of the side: $l=5in$

thus the area of the square is:

$a_{square}=(5in)^2$

$a_{square}=25in^2$

Area of the triangles:

the are of 1 triangle is given by

$a_{triangle} =\frac{b*h}{2}$

where $b$ is the base of the triangle: $b=5in$ (the base of the triangle is the side of the square)

and $h$ is the height of the triangle: $h=6in$

thus, the area of 1 triangle is:

$a_{triangle} =\frac{(5in)*(6in)}{2}$

$a_{triangle} =\frac{30in^2}{2}$

$a_{triangle} =15in^2$

the area of the 4 triangles is (we multiply by 4):

$a_{4-triangles}=4(15in^2)$

$a_{4-triangles}=60in^2$

finally we add the area of the square and the area of the 4 triangles to find the total surface area:

$Surface=25in^2+60in^2$

$Surface=85in^2$

Answer:

see below

Step-by-step explanation:

Option 1: the two solution sets overlap at <em>x=1</em>.

Option 2: the two solution sets do not overlap; no solution.

Option 3: together, the two set describe <em>all real numbers</em>.

What two numbers you can add together to give you 27 and also multiply the two numbers to give 60

Vera_Pavlovna [14]

There are none that work, the only close two are 3 and 24 + 2 and 25, but they multiply to 72 and 50, but if you can use decimals, you could use 2.445+24.555
