8 0

Answer: x=8 and x=-8

Step-by-step explanation:

To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.

x²-16=0

(x+8)(x-8)=0

x+8=0

x=-8

x-8=0

x=8

Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.

1. A student invests $500 in a savings account that earns 4% interest per

bixtya [17]

Answer:

The equation can be used to determine the amount of money S(t) that her savings account has after t years is $S(t)=500(1.04)^t$

Step-by-step explanation:

A student invests $500 in a savings account

Principal = $500

Rate of interest = 4% = 0.04

We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years

Formula : $A=P(1+r)^t$

Where A is the amount after t years =S(t)

t = time

r = rate of interest in decimals =0.04

P = Principal=500

Substitute the value in the formula :

So, $S(t)=500(1+0.04)^t$

$S(t)=500(1.04)^t$

Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is $S(t)=500(1.04)^t$

Find mL 1 and mL 2.

lesantik [10]

Answer:

8. ∠1=118° ∠2=118°

9. ∠1=72° ∠2=108°

10. ∠1=127° ∠2=127°

Step-by-step explanation:

8. In this problem, 118° is corresponding to ∠1, meaning they are congruent. ∠2 is supplementary with ∠1, meaning that together, they equal 180°. So, to get ∠2, you must subtract 118° from 180°

9. In this problem, 72° is same side interior with ∠1, meaning they are congruent. ∠2 is supplementary with ∠1, so you do 180°-72°= 108°

10. In this problem, ∠1 is vertical angles with 127°, making them equal to each other. ∠2 is corresponding with 127°, making them also equal.

Is there a rational number between 1/7 and 1/8

telo118 [61]

1/7 = 2/14 = 0.1428571429 
1/8 = 2/16 = 0.125
2/15 = 0.1333333333 
So, 2/15 is between 1/7 and 1/8
(and there are an infinite amount of numbers between 1/7 and 1/8)
