Answer:
11 cats
Step-by-step explanation:
Given :
Jane's initial = 23
My initial = 2
Jane gives out 5 cats to me ;
Jane's new = 23 - 5 = 18
My new = 2 + 5 = 7
Number of cats Jane has than me :
Jane's new - My new
18 - 7 = 11 cats
Second question is incomplete. We aren't told what to calculate.
Answer:
y=2x-3
Step-by-step explanation:
<em>Since we know that the slope-intercept form is </em><em>y=mx+b</em><em>, we can plug in the formula with what we already know to find b!</em>
<em>In the coordinates (2,1): </em>
<em>Now, we will plug these numbers in:</em>
1=2*2+b
1=4+b
b=-3
<em>Now we can rewrite the equation since we found b:</em>
y=2x-3

Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds

There may be an error with the first answer choice because it can't have a negative. The problem is x + 2.6 = 3.5 correct?
Hope this helps!
