Graph f(x) =-2x^+16x-30 by factoring to find the solutions, then find the coordinates of the vertex, and the axis of symmetry. I
inn [45]

Answer:

See explanation

Step-by-step explanation:

1. Factor the function f(x)=-2x^2+16x-30:

f(x)=-2x^2+16x-30=-2x^2+6x+10x-30=-2x(x-3)+10(x-3)=-2(x-3)(x-5).

2. The zeros (or the solutions of the equation f(x)=0) are x=3 and x=5. So? points (3,0) and (5,0) are the points on the graph that are the solutions of the equation.

3. Find the vertex:

x_v=-\dfrac{b}{2a}=-\dfrac{16}{2\cdot (-2)}=4,\\ \\y_v=-2\cdot 4^2+16\cdot 4-30=-32+64-30=2.

Thus, the coordinates of the vertex are (4,2) and the axis of symmetry is the vertical line that passes trough the vertex: x=4.

A recipe for 10 servings of raspberry sorbet calls for 2 cups of water, 1ż cups of granulated sugar, and 4 cups of
ehidna [41]

Answer:

\huge\boxed{\sf 320\ servings = 4\ gallons}

Step-by-step explanation:

1 gallon = 16 cups (STANDARD)

For 10 servings:

10 servings = 2 cups of water

10 servings = 2 / 16 gallons

10 servings = 0.125 gallons

<u>For 320 servings:</u>

10 servings = 0.125 gallons

Multiply both sides by 32

10 * 32 servings = 0.125 * 32 gallons

320 servings = 4 gallons

\rule[225]{225}{2}

Hope this helped!

Mr. Carson washes his car every 8 days, checks the oil every 7
myrzilka [38]

The first day when he would do these activities on the same day is December 7, 2023.

<h3>When would he do these activities on the same day?</h3>

In order to determine which day Mr. Carson would wash his car, check his oils and check the tire pressure, the multiple of 8, 7, and 9 have to be determined.

A multiple of a number is the product of an integer and that number. A common multiple is a number that is common to all three numbers. The lowest common multiple of 8, 7 and 9 is 504. So, in 504 days he would do all three activities on the same day.

In order to convert 504 days, take note of the following:

365 days = 1 year

12 month = 1 year

1 month = 4 weeks

30 days = 1 month

504 / 365 = 1 year 139 days

139 days / 30 days  = 4 months 19 days

504 days = 1 year, 4 months and 19 days

1 year, 4 months and 19 days + July 18, 2022 = December 7, 2023
