Write an exponential function whose graph passes through the points (0,-2) and (2,-50)

Answers

Answer:

first sub in (0,-2) to get

-2 = ab^0, but b^0 = 1

so a=-2

so far we have

y = -2b^x

now use the other point (2,-50)

-50 = -2(b^2)

b^2 = 25

b= ±5

however in exponentional equations the base is usually positve, so now you have

y = -2(5^x)

sub in x=-2 and you got it.

Find the value of x in the triangle shown below.
10.4
62°
12
12

Answers

Two of the sides are the same (12) so the two angles at the top will also be the same, so you have two angles that are 62.

62 + 62 = 124

The three angles of a triangle need to equal 180.

X = 180-124 = 56

The answer is x = 56

common denominator for 3/5 and 1/2

Answers

Answer: 10

Step-by-step explanation:

To find a common denominator, simply multiply the denominator and numerator of one fraction by the denominator and numerator of the other. Then repeat.

3*2/5*2 = 6/10

1*5/2*5=5/10

As you can see, the denominator of both fractions is 10.

l=prt
you have to solve for t

Answers

Answer:

T is equal to I divided by pr. [tex]t=\frac{I}{pr}[/tex]

Step-by-step explanation:

This is the equation for interest.

I is interest.

P is the principal

r is the interest rate

t is the time in years

you have to isolate for t.

Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication

Then you are left with t= i divided by pr.

Make x the subject of h = 4(x + 3y) + 2
You may use the flowchart to help you if you wish.

Answers

Answer:

x = {(h-2)/4} -3y

Step-by-step explanation:

Here, we want to make x the subject of the formula

h = 4(x + 3y) + 2

h-2 = 4(x + 3y)

divide both sides by 4

(h-2)/4 = x + 3y

x = (h-2)/4 -3y

Simplify the expression: (3 − 7i)(2 − 5i)

Answers

Answer:

( 3 - 7i) • ( 2 - 5i) = ( - 29 - 29i)

Step-by-step explanation:

The formula is :

(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i

and since i^2 = -1 it can be written as :

ax - by + (ay + bx) i

( 3 - 7i) • ( 2 - 5i) =

( - 29 - 29i)
