Solve for a.<br> a^2=-3a+88

Sergio [31]

Answer:

$a=8,-11$

Step-by-step explanation:

$a^2=-3a+88$

$a^2+3a=88$

$a^2+3a-88=0$

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$x=\frac{-3\pm\sqrt{3^2-4(1)(-88)} }{2(1)}$

$x=\frac{-3\pm\sqrt{9+352} }{2}$

$x=\frac{-3\pm\sqrt{361} }{2}$

$x=\frac{-3\pm19 }{2}$

$x=-11$ and $x=8$

Therefore, the values of $a$ are 8 and -11.

Sasha does push-ups each day for five days. The numbers of push-ups she does each day or shown below.

lana [24]

The mean average of push ups Sasha does in 5 days is 26.2.

<h3>Mean average</h3>

Number of days = 5
Day 1 = 22 push ups
Day 2 = 36 push ups
Day 3 = 21 push ups
Day 4 = 25 push ups
Day 5 = 27 push ups

Mean average = Total push ups done / number of days

= (22 + 36 + 21 + 25 + 27) / 5

= 131 / 5

= 26.2

Therefore, the mean average of push ups Sasha does in 5 days is 26.2.
