1).  The inequality says "height is 54 or more".
Any height that is less than 54 does NOT qualify.

Any weight that's 800 pounds or less is OK.

When Albert was born, he was 19.5 inches "tall". Today, on his 13th birthday, Albert is four feet, nine inches.
Ivanshal [37]

Answer: 76.5in or 6.37ft

Step-by-step explanation:

You would convert the 4 feet into inches which would be 48in. You would add the 9in and the 19.5in and come up with 76.5in. Then you just convert the 76.5in to 6.375ft

If if f(x)=3x+1 and g(x)=x^2-1 find fog(2)
Ymorist [56]
I think this is a repeat question from yesterday.

f(x)=3x+1
g(x)=x^2-1

f o g (x) = f(g(x))=f(x^2-1)=3((x^2-1))+1=3x^2-3+1=3x^2-2
f o g(2)=3(2^2)-2=3(4)-2=10

Five thousand dollars is deposited into a savings account at 2.5% interest compounded continuously.
Mumz [18]

Answer:

A). A(t) = P(1+r/n)^(nt)

B). DA/Dt = np(1+r/n)^(t)

C). A(5) =$ 5664.0

D).t = approximately 13.5 years

Step-by-step explanation:

A(t) = P(1+r/n)^(nt)

P = $5000

n= t

r= 2.5%

After five years t = 5

A(t) = P(1+r/n)^(nt)

A(5) = 5000(1+0.025/5)^(5*5)

A(5) = 5000(1+0.005)^(25)

A(5)= 5000(1.005)^(25)

A(5) = 5000(1.132795575)

A(5) = 5663.977875

A(5) =$ 5664.0

When the balance A= $7000

A(t) = P(1+r/n)^(nt)

7000= 5000(1+0.025/n)^(nt)

But n= t

7000= 5000(1+0.025/t)^(t²)

7000/5000= (1+0.025/t)^(t²)

1.4= (1+0.025/t)^(t²)

Using trial and error

t = approximately 13.5 years
