Caleb - c
Kyras - k

k+c=37
c=2k-4

k+(2k-4)=37

k=41/3= ~13.67 years old

c=37-k
c=(111-41)/3
c=70/3=~23.33 years old

Write an equation in slope-intercept form for the line passing through the following pair of points: (2, -6), -4, 3).
saveliy_v [14]

The equation in slope intercept form is y=-\frac{3}{2} x-3

Explanation:

The given pair of points are (2,-6) and (-4,3)

The slope can be determined using the formula,

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the points (2,-6) and (-4,3) in the slope formula, we have,

m=\frac{3+6}{-4-2}

m=\frac{9}{-6}

m=-\frac{3}{2}

The equation in slope intercept form can be determined using the formula,

y-y_1=m(x-x_1)

Substituting m=-\frac{3}{2} and the point (2,-6) in the above formula, we get,

y+6=-\frac{3}{2} (x-2)

y+6=-\frac{3}{2} x+3

   y=-\frac{3}{2} x+3-6

   y=-\frac{3}{2} x-3

Thus, the equation in slope intercept form is y=-\frac{3}{2} x-3

A ball is shot from a cannon into the air with an upward velocity of 65 ft/sec. The equation that gives the height (h) of the ba
Sveta_85 [38]

Answer:

Step-by-step explanation:

Find AOS

X = -b/2a

X = -65/2(-14)

X = -65/-28

X = 2.32 secs

t = 2.32secs

A) y value when t = 2.32 is the maximum height.

Substitute t in the equation.

h(t)= -14t^2+65t+1.75

h(t)= (-14 * 2.32²) + (65 * 2.32) + 1.75

= (-14 * 5.38 ) + (65 * 2.32) + 1.75

= -75.35 + 150.8 + 1.75

= 77.2 ft

Maximum height attained by the ball = 77.2 ft

B) Time the maximum height achieved = 2.32secs

C) The ball off of the ground when it was shot is well t = 0

Substitute t in equation

h(t)= -14t^2+65t+1.75

h(0)= (-14 * 0²) + (65 * 0) + 1.75

= 0 + 0 + 1.75ft

The ball is 1.75ft off the ground when it was shot.
