Answer:

1. B. a=14, b=2

2. D. a=1, b=1.4

Step-by-step explanation:

The exponential growth function can be represented as

$y=a\cdot b^x,$

where b is the growth factor.

1. When the function has equation

$g(x)=14\cdot 2^x,$

then

$a=14,\\ \\b=2$

The initial amount is the value of the function at x=0:

$g(0)=14\cdot 2^0=14\cdot 1=14$

The growth factor is b=2

2. When the function has equation

$f(t)=1.4^t,$

then

$a=1,\\ \\b=1.4$

The initial amount is the value of the function at t=0:

$f(0)=1.4^0=1$

The growth factor is b=1.4

4 x 5= 20

9-20 = -11

-11 + 6 = -5

Can plz help answer number 4

enot [183]

Answer:

It was 6 7/8 pounds of fruit in the fruit salad.

Step-by-step explanation:

Regina bought in total (in pounds) of fruit: B

$B=3\frac{1}{2}+4\frac{3}{4}\\ B=\frac{3(2)+1}{2}+\frac{4(4)+3}{4}\\ B=\frac{6+1}{2}+\frac{16+3}{4}\\ B=\frac{7}{2}+\frac{19}{4}\\ B=\frac{7}{2}.1+\frac{19}{4}\\ B=\frac{7}{2}.\frac{2}{2}+\frac{19}{4}\\ B=\frac{7(2)}{2(2)}+\frac{19}{4}\\ B=\frac{14}{4}+\frac{19}{4}\\ B=\frac{14+19}{4}\\ B=\frac{33}{4}$

Regina bought in total 33/4 pounds of fruit

She used all (33/4 pounds) but 1 3/8 pounds of the fruit in a fruit salad, then she used in the fruit salad (in pounds): S

$S=B-1\frac{3}{8}\\ S=\frac{33}{4}-\frac{1(8)+3}{8}\\ S=\frac{33}{4}-\frac{8+3}{8}\\ S=\frac{33}{4}-\frac{11}{8}\\ S=\frac{33}{4}.1-\frac{11}{8}\\ S=\frac{33}{4}.\frac{2}{2}-\frac{11}{8}\\ S=\frac{33(2)}{4(2)}-\frac{11}{8}\\ S=\frac{66}{8}-\frac{11}{8}\\ S=\frac{66-11}{8}\\ S=\frac{55}{8}\\ S=\frac{48+7}{8}\\ S=\frac{48}{8}+\frac{7}{8}\\ S=6+\frac{7}{8}\\ S=6\frac{7}{8}$

It was 6 7/8 pounds of fruit in the fruit salad.
