Answer:

7.63 ounces of strawberries + 5.26 ounces of blueberries

7.63 + 5.26= 12.89 - 1.37 left over = 11.52 to be split between 2 bowls equally

11.52/2 = 5.76 per bowl

5.76 ounces of fruit in each bowl.

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given,

strawberries = 7.63 ounces

blueberries = 5.26 ounces

Put the fruits into two equal bowls in equal amounts

let the amount be x

remaining amount = 1.37 ounces

According to the statements, we can state that,

2x + 1.37 = 7.63 + 5.26

2x = 11.52

x = 5.76

Therefore, the two bowl contains 5.76 ounces of fruit each.

Answer: a unit rate is a rate with 1

Step-by-step explanation:

The vertex of the given quadratic function is (-3, 0).

The vertex form of a quadratic equation or function is [tex]f(x)=a(x-h)^{2} +k[/tex].

Where,

(h, k ) is the vertex

And, a is constant.

According to the given question

We have a quadratic function

[tex]f(x) = x^{2} + 6x + 9[/tex]

The above function can be written as  

[tex]f(x) = x^{2} +2(3x) +9[/tex]

⇒[tex]f(x) = x^{2} + 2(3x) + (3^{2}) -(3)^{2} + 9[/tex]

⇒[tex]f(x) = (x+3)^{2} -9+9[/tex]

⇒[tex]f(x) = (x+3)^{2} + 0[/tex]

Comparing the above equation with the standard  vertex form of quadratic function we get

h = -3 and k = 0

Hence, the vertex of the given quadratic function is (-3, 0).

Thus, option A is correct.

Answer:

[tex]a_{n}[/tex] = 3[tex](2)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio r between consecutive terms in the sequence, that is

6 ÷ 3 = 12 ÷ 6 = 24 ÷ 12 = 48 ÷ 24 = 2

This indicates the sequence is geometric with n th term

[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 3 and r = 2 , thus

[tex]a_{n}[/tex] = 3[tex](2)^{n-1}[/tex]
