Answer:
1/5 and -k/5+2
Step-by-step explanation:
inverse of 5= 1/5
swap the variables: y=10−5k becomes k=10−5y
Now, solve the equation k=10−5y
for y
y=−k/5+2
Multiply 120 times .7 because you just Turn the percent into a decimal
The coordinates of the point that divides the segment into a 3:2 ratio is (-2.2, -1.2)
<h3>How to determine the coordinate?</h3>
The points are given as:
G = (-4,3)
H = (-1,-4)
Ratio, m : n = 3 : 2
The coordinate of the point is calculated using:

This gives

Evaluate

Evaluate the product
(x,y) = (-2.2, -1.2)
Hence, the coordinate of the point is (-2.2, -1.2)

Answer:
=1.283 , 0.779 seconds
Step-by-step explanation:
h=2+33t-16t²
when h=18 ft
then18=2+33t-16t²
→ 16t²−33t+16=0
t= [−(−33)±√{(−33) ²−4×16×16)}]/(2×16)
= [33±√{1089−1024}]/(32)
= [33±√{65}]/(32)
=1.283 , 0.779 seconds
