Answer:

The correct options are the second and fifth choices, as those were confirmed right in the algebra course I took.

The solution is f(X)= -2x^2 + 12x - 5, or it matches best with the second alternative.

By utilizing -b/2a, you will find that the outcome is three, which indicates the duration it takes for the ball after it is served.

Substituting this number into the quadratic equation should yield thirteen as the result.

Find x if a =13 and C = 47 need help
Inessa [12570]

You can utilize the Pythagorean theorem expressed as a^2 + b^2 = c^2... if b is unknown, you can rearrange the formula. Hence, c^2 - a^2 = b^2. Squaring 47 gives 2209 and squaring 13 yields 169... Subtracting gives you 2209-169, which results in 2040. Taking the square root of that yields approximately 45.166359, which can be rounded to 45 or as 45.167 when expressed to two decimal places. I hope this helps!:)

A grocery store wants to examine the relationship between the sales amounts each day at two different locations, store A and sto
Leona [12618]

Response:

The average of the 10 sales figures for store A is $40,000.

Detailed explanation:

Provided;

yˆ= −3,000 + 1.2x...................... (1)

Where;

x = daily sales amounts at store A or the average of the 10 sales amounts for store A =?

yˆ = daily sales amounts at store B or the average of the 10 sales amounts for store B = $45,000

Substituting y = 45,000 into equation (1) and solving for x, yields:

45,000 = −3,000 + 1.2x

45,000 + 3,000 = 1.2x

48,000 = 1.2x

x = 48,000 / 1.2

x = 40,000

Consequently, the mean of the 10 sales figures for store A is $40,000.

Answer:

43.2in

Step-by-step explanation:

If the two individuals maintain proportionality, then with the waist measurement of one person known, we can determine the other's waist size through the established ratio.

36in*(1*20%) = 36in*1.2 = 43.2in
