These are exponents. To solve an exponent you need to multiply the base it self how many times its says in the power.

a²

a = base
2 = power

7^5 = 7 × 7 × 7 × 7 × 7 = 16807
7^5 = 16807

Answer: x = {-4, 5}

Step-by-step explanation:

log (10x + 200) = log (x²) + log (10)

log (10x + 200) = log (10x²)

10x + 200 = 10x²

0 = 10x² - 10x - 200

0 = x² - x - 20

0 = (x - 5)(x + 4)

0 = x - 5 0 = x + 4

x = 5 x = -4

Check for extraneous solutions:

10x + 200 > 0 x² > 0

x = 5 10(5) + 200 > 0 (5)² > 0 both are satisfied

x = -4 10(-4) + 200 > 0 (-4)² > 0 both are satisfied

Both solutions are valid!

Can someone please help me with math.

Oxana [17]

Answer:

Step-by-step explanation:

Hello There!

First thing we notice is that the y intercept is at (3,0) meaning that they have some sort of fee that has a charge of 3 dollars (represented by the 3)

Because the fee is 3 dollars we can immediately eliminate answers B and C

Now we want to find the charge for each bag of Potpourri (this can be represented by the slope)

Once again we want to choose two points on the line and plug it in into the slope formula

the points are optional but i have chosen the points (1,4.5) and (2,6)

*plug it into the slope formula*

$slope=\frac{6-4.5}{2-1} \\6-4.5=1.5\\2-1=1\\slope =\frac{1.5}{1} or1.5$

so we can conclude that the charge per bag of potpourri is $1.50 leading us to answer choice A

(9CQ) Find the distance from the balloon to the soccer fields.

almond37 [142]

Answer:

The distance from the balloon to the soccer fields = 3.6 miles ⇒ answer (b)

Step-by-step explanation:

* Let the hot air balloon at point A , the soccer fields

at point B and the football field at point C

∵ The measure of the angle of depression to the

soccer fields is 20° 15'

∴ The measure of angle B = 20° 15'

∵ The measure of the angle of depression to the

football field is 62° 30'

∴ The measure of angle C = 62° 30'

∵ The sum of measures of the interior angles of any triangle = 180°

∴ The measure of angle A = 180 - (20° 15' + 62° 30') = 97° 15'

* The distance between the balloon and the soccer field

is represented by the side AB of triangle ABC

- Use the sin Rule to find the length of side AB

∵ a/sin(A) = b/sin(B) = c/sin(C)

- a is the side opposite to angle A, b is the side opposite

to angle B and c is the side opposite to angle C

∵ AB = c ⇒ opposite to angle C

∵ The distance between the two fields = 4 miles

∴ BC = 4 miles

∵ BC = a ⇒ opposite to angle A

∴ 4/sin(97° 15') = c/sin(62° 30')

∴ c = (4 × sin(62° 30')) ÷ sin(97° 15')

∴ c = 3.6 miles

∴ The distance from the balloon to the soccer fields = 3.6 miles

answer (b)
