3a + 1 = -3.6(a - 1) \\\\3a + 1 = -3.6 a +3,6\ \  | \ add\ 3.6a\ to\ both\ sides  \\ \\ 3a + 3.6a+1 = 3,6\ \ |\ subtract\ 1\ to\ both\ sides \\\\6.6a=3.6-1 \\\\ 6.6a=2.6 \ \ | \ multiply\ both\ sides\ by\ 10  \\\\66a=26 \ \ | \ divide \ both \ sides\  by\ 66\\\\a=\frac{26}{66}\\\\a=\frac{13}{33}

The function H(t) = −16t2 + 75t + 25 shows the height H(t), in feet, of a baseball after t seconds. Part A: After how many secon
nlexa [21]

Step-by-step explanation:

Given that,

The function that shows the height of a baseball after t seconds is given by :

H(t)=-16t^2+75t+25 ....(1)

Part (A).

When the baseball hits the ground,

H(t) = 0

So,

-16t^2+75t+25=0\\\\t=5\ s\ and\ t=-0.31\ s

After 5 seconds the baseball will hit the ground.

Pat (B)

For maximum height, put dH/dt = 0

So,

\dfrac{d}{dt}(-16t^2+75t+25)=0\\\\-32t+75=0\\\\t=2.34\ s

Put t = 2.34 s in equation (1).

H(t)=-16(2.34)^2+75(2.34)+25\\\\H(t)=112.89\ m

Hence, this is the required solution.

3. Solve y = 2(x - 3) when:<br>a. X = 4<br>b. y = 8​
eimsori [14]

Answer:

Hello!

Ok so first you plug in y as 8 and x as 4. You first do the math in the parentheses so 4-3 is 1, then 1 times 2 is 2. It should be like this 8=2. Then you do 8 divided by 2 which is 4.
