Answer:

7290

Step-by-step explanation:

Put 5 in the formula and evaluate.

a(5) = 90·3^(5-1) = 90·81 = 7290

There will be 7290 bacteria at the beginning of hour 5.

Answer:

-10

Step-by-step explanation:

You always want to solve the inner function first.

g(-2)=(-2)³+3

=-8+3

=-5

g(-2)=-5 so you can replace g(-2) with -5

Now you just have f(-5)

Solve.

f(-5)=-5-5

f(-5)=-10

The vertical angle to the top of a flagpole from point A on the ground is observed to be 37°11'. The observer walks 17 m directl

inysia [295]

Answer:

22m

Step-by-step explanation:

Let height of flagpole=h

AB==17 m

$\angle CAD=37^{\circ}11'=37+\frac{11}{60}=37.183^{\circ}$ (1 degree= 60 minute)

$\angle B=25^{\circ}43'=25+\frac{43}{60}=25.72^{\circ}$

We have to find the approximate height of the flagpole.

In triangle CDA,

$\frac{CD}{DA}=tan\theta=\frac{Perpendicular\;side}{Base}$

$\frac{h}{DA}=tan37.183^{\circ}$

$h=DA(0.759)$

In triangle CDB,

$tan 25.72^{\circ}=\frac{CD}{DB}$

$0.482=\frac{h}{DA+17}$

$0.482DA+8.194=h$

Substitute the value

$0.482DA+8.194=0.759DA$

$8.194=0.759DA-0.482DA$

$8.194=0.277DA$

$DA=\frac{8.194}{0.277}=29.58$

Substitute the value

$h=29.58 \times 0.759=22.45 m\approx 22m$

Hence, the height of the flagpole=22 m

Write -9/2 divided by 7/5 as a multiplication expression

nordsb [41]

(-9/2)/(7/5)
= (-9/2)*(5/7)
= -45/14
= -3 3/14

The final answer is -3 3/14~
