What is the perimeter of the figure?​
rewona [7]

Answer:

Oh! We should start with finding the lngths of the "curvy sides". As you can see there are 2 semi circles which we can combine to make one circle with a diameter of 7. The formula for the circumference of the circle is 2πr which is also equal to the diameter x π. SO the circumeference is 7π which is this case equals 22 since they are telling us to use  π as 22/7. I'm not sure about the rest but I hope this helped a little!!

Let a represent the number of ounces of perfume A. Let b represent the number of ounces of perfume B. Perfume A costs $11 per ou
Julli [10]

Answer:

The system of equations in standard form is equal to

11a+19b=71

a+b=5

The number of ounces of perfume A is 3\ ounces

The number of ounces of perfume B is 2\ ounces

Step-by-step explanation:

Let

a-----> the number of ounces of perfume A

b----> the number of ounces of perfume B

we know that

11a+19b=71 -----> equation A

a+b=5

a=5-b -----> equation B

substitute equation B in equation A and solve for b

11(5-b)+19b=71

55-11b+19b=71

8b=71-55

8b=16

b=2\ ounces

Find the value of a

a=5-b -----> a=5-2=3\ ounces

WILL PICK BRAINLIEST!!!
andreyandreev [35.5K]

we are given

f(x)=10(2)^x

now, we can compare it with

f(x)=a(b)^x

we can find b

we get

b=2

now, we are given

How would the graph change if the b value in the equation is decreased but remains greater than 1

Let's take

b=1.8

f(x)=10(1.8)^x

b=1.6

f(x)=10(1.6)^x

b=1.4

f(x)=10(1.4)^x

b=1.2

f(x)=10(1.2)^x

now, we can draw graph

now, we will verify each options

option-A:

we know that all y-value will begin at y=0

because horizontal asymptote is y=0

so, this is FALSE

option-B:

we can see that

curve is moving upward when b decreases for negative value of x

but it is increasing slowly for negative values of x

so, this is FALSE

option-C:

we can see that

curve is moving upward when b decreases for negative value of x

but it is increasing slowly for negative values of x

so, this is TRUE

option-D:

we know that curves are increasing

so, the value of y will keep increasing as x increases

so, this is TRUE

option-E:

we can see that

curve is moving upward when b decreases for negative value of x

but it is increasing slowly for negative values of x

so, this is FALSE
