(√-15)(√-6), with steps please. Thank you.

1 answer:

6 0

If you mult. these two radicals together, you'll combine the radicands -15 and -6 into one amount: 90, and this 90 is under the radical: sqrt(90).

Now, 9 is a perfect square, tho' 10 is not. Thus, sqrt(90) = 3sqrt(10) (ANSWER)

Tom works 14 hours a week for 10 weeks and earns a total of $1,351.00. How much money does he make per hour?

vagabundo [1.1K]

14 hours a week
works 10 weeks

totally $14 \frac{hours}{week} \ *\ 10 weeks\ =\ 140\ hours$

earns $1,351

so $\frac{1,351}{140} \frac{\$}{h} =9,65$

He makes $9,65 per hour.

Step-by-step explanation:

x+13⁰+10x+13⁰+2x-2⁰= 180⁰

13x= 180-24

13x=156

x = 12⁰

now angle Q = 10x+13⁰

= 10(12)+13= 120+13

= 133⁰

Write an exponential function in the form y=ab^x that goes through points (0,14) and (3,3024).

Dmitrij [34]

Answer:

y = 14 $(6)^{x}$

Step-by-step explanation:

For an exponential function of the form y = a $b^{x}$

Use the given points to find a and b

Using (0, 14 ), then

14 = a $b^{0}$ ( $b^{0}$ = 1 ) , thus

a = 14

y = 14 $b^{x}$

Using (3, 3024 ) , then

3024 = 14 b³ ( divide both sides by 14 )

216 = b³ ( take the cube root of both sides )

b = $\sqrt[3]{216}$ = 6 , thus

y = 14 × $6^{x}$ ← exponential function

17. El precio de los terrenos en Lima es proporcional al área e inversamente proporcional a su distancia con respecto al centro

grin007 [14]

Answer:

375000

Step-by-step explanation:

We have that in this case the following proportion would be fulfilled:

Price * Distance / area

Now, we have that for a distance of 45 km and an area of 900 m ^ 2 the price is 250,000, now for a distance of 40 km but with an area of 1,200 m ^ 2, how would the price be, we replace:

250000 * 45/900 = P * 40/1200

12500 * 1200/40 = P

P = 375000

Which means that for these conditions the price is 375000.
