Answer:

3,000 ft per hour

Step-by-step explanation:

We know that 1 minute of driving gets us 50 ft of distance. We also know that there are 60 minutes in an hour. You can multiply 50 (ft per minute) by 60 (number of minutes in an hour) to get the number of ft per hour.

Answer:

y = 3/4x + 9/4

Step-by-step explanation:

(1,3) and (-3,0)

to find the slope of the line we use the formula of finding the difference of the y-values over the difference of the x-values

slope ('m') = [tex]\frac{(3-0)}{(1-(-3))}[/tex]

m = 3/4

now we can use the slope-intercept form of a line to find the y-intercept:

y = mx + b

'x' and 'y' are values from a given point, 'm' is the slope, and 'b' is the y-intercept

3 = 3/4(1) + b

3 - 3/4 = b

2 1/4 = b  Always put slope in a/b form

9/4 = b

Step-by-step explanation:

You can prove the triangle congruent by SAS. First, reflexive property and then isosceles triangle theorem since two side is congruent, the opposite angle is congruent to each other because of that theorem and then cpctc

Answer:

x = 2

Step-by-step explanation:

This triangle isosceles because of it's two marked congruent sides.

Using base angle theorem, reflexive property (the line in the middle is congruent to itself), and given, we can prove that the two triangles are congruent.

Now that we have proved triangle congruency (SAS), we know that:

17x-3 = 9x+13

Plus 3 on both sides and minus 9x on both sides

8x = 16

Divide by 8 on both sides to isolate x

x = 2

Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity.

The height of a projectile is given as;

H = u²sin²(θ)/2g

where u is the initial velocity and g is the gravity

Therefore when h /d = 24ft

24 = u² × 1/4 /20

u² = 1600

u = √1600

u = 40.000ft/s

When d = 32ft

u² = 32 × 20 × 4

u² = 2560

u = √2560

u = 50.596 ft/s.
