a scientist has two solutions which she has labeled solutions A and solution B each contains salt. she knows that solution A is
loris [4]

Answer

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 180        y = 180 - x

.60x + .85y = .75(180)

.60x + .85y = 135      Multiply both sides of the equation by 100 to remove the decimal points.

60x + 85y = 13500

60x + 85(180 - x) = 13500

60x + 15300 - 85x = 13500

-25x = -1800

x = 72ounces

y = 180 - 72

y = 108 ounces

Plz help asap this table represent a quadratic function with a vertex a (1,2) what is the average rate of change for the interva
Advocard [28]

Answer:

9

Step-by-step explanation:

Given that (1, 2) is the vertex of the function represented by the table of values above, the rate of change for the interval from x = 5 to x = 6.

f(5) = 18

f(6) = ?

=>Find f(6) using the vertex form function, f(x) = a(x - h)² + k

Where, h and k are the given vertex of the function = (1, 2).

h = 1, k = 2

Thus,

f(x) = a(x - 1)² + 2

Find the value of a by using any of the points given in the table.

Using (3, 6), we have the following,

6 = a(3 - 1)² + 2

6 = a(2)² + 2

6 = 4a + 2

Subtract 2 from both sides

6 - 2 = 4a

4 = 4a

Divide both sides by 4

1 = a

a = 1

Let's find f(6) using f(x) = a(x - 1)² + 2

Plug the value of a and x

f(6) = 1(6 - 1)² + 2

f(6) = 25 + 2

f(6) = 27

==>Find the rate of change/slope

f(5) = 18

f(6) = 27

Rate of change =

\frac{f(6) - f(5)}{6-5}

\frac{27- 18}{6-5}

\frac{9}{1}

Rate of change = 9

Will a stand that can hold up to 40 pounds support a 21-kilogram television?
LUCKY_DIMON [66]
1 kg = 2.20 pound
21kg = 21 x 2.20 = 46.2 pounds

Since the tv is heavier than the stand can support. The stand will not support the tv.
