Ab" that goes through points (0,9)<br> Write an exponential function in the form y<br> and (5,2187)

Answer:

y = 9(3^x)

Step-by-step explanation:

We assume you want a function in the form ...

y = a(b^x)

that passes through points (0, 9) and (5, 2187).

Filling in the given point values, we have ...

9 = a(b^0) = a

2187 = a(b^5) = 9(b^5) . . . . using the above value of 'a'

Dividing the second equation by 9 and taking the 5th root, we find b.

(2187/9) = b^5

243^(1/5) = b = 3

The exponential function is ...

y = 9(3^x)

Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change. How much did each avocado cost i

Delvig [45]

Answer:

$1.10

Step-by-step explanation:

We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.

First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.

$\text{Amount paid for 5 avocados}=\$10-\$4.50$

$\text{Amount paid for 5 avocados}=\$5.50$

Now, we will divide $5.50 by 5 to find cost of each avocado.

$\text{Cost of each avocado}=\frac{\$5.50}{5}$

$\text{Cost of each avocado}=\$1.10$

Therefore, the cost of each avocado is $1.10.

To French shop for fresh fruit. Elena buys a watermelon for $7.75 and 5 pounds of cherries Tammy buys a pineapple for $4.15 and

lys-0071 [83]

Answer: Elena spent $3.6 +x more than Tammy.

Step-by-step explanation:

Let the cost of each cherry be 'x'.

Cost of watermelon for Elena = $7.75

Cost of 5 pounds of cherries = 5x

So, Equation for Elena would be

$7.75+5x$

Cost of pineapple = $4.15

Number of pounds of cherries = 4

So, Equation for Tammy would be

$\$4.15+4x$

Now, Elena spent more than Tammy by

$(7.75+5x)-(4.15+4x)\\\\=7.75+5x-4.15-4x\\\\=3.6+x$

Hence, Elena spent $3.6 +x more than Tammy.
