The answer is D y=4x^2-16x+15

Gwar [14]3 years ago

For this case we have the following equation:
y = 4 (x-2) ^ 2-1
Rewriting we have:
y = 4 (x ^ 2-4x + 4) ^ 2-1
Multiplying the common factor 2 we have:
y = 4x ^ 2-16x + 16-1
Adding the constant term we have:
y = 4x ^ 2-16x + 15
Answer:
y = 4x ^ 2-16x + 15
option D

The product of the ages of three children is 1872. The age of the middle child is the average of the ages of the other two child

sergejj [24]

The total age of the three children are = 37years

<h3>Calculation of the total age of children</h3>

The product of the ages of three children is = 1872.

Let take child 1 = x

child 2 = x

child. 3 = x

Therefore, the age of three children = x³= 1872

Therefore;

$x = \sqrt[3]{1872}$

X = 12.32448

The age of the middle child = 12.32448 + 12.32448

= 24.64896/2

= 12.32448

Therefore the sum of their ages = 12.32448 + 12.32448 + 12.32448 = 37years.

Need help with problem 40,41 and 42! 15 points

vovikov84 [41]

Answer:

40) w = 32/3

41) x = 23/4

42) w = 1/12

Step-by-step explanation:

40) Real world problem:

If Lisa takes $7\frac{3}{8}$ of the pie from a total of $w$ slices, then the remaining pie is $3 \frac{7}{24}$ . Find w.

So, the equation would become:

$w - 7 \frac{3}{8} = 3 \frac{7}{24}$

$\implies w = 3 \frac{7}{24} + 7 \frac{3}{8}$

This can be written as:

$w = 3 + \frac{7}{24} + 7 + \frac{3}{8}$

This is equivalent to $3 + \frac{7}{24} + 7 + \frac{9}{24}$

Since, the denominator is the same, the numerators can be added now.

$\implies w = 10 + \frac{16}{24}$

$\implies w = 10 + \frac{2}{3}$

$i.e., w = 10 \frac{2}{3} = \frac{32}{3}$

Hence, the answer is 32/3.

41) The given equation is: $2 \frac{1}{2} + x = 8\frac{1}{4}$

$2 \frac{1}{2} = \frac{5}{2}$ and

$8 \frac{1}{4} = \frac{33}{4}$

So, $x = \frac{33}{4} - \frac{10}{4}$

$\implies x = \frac{23}{4}$

The answer is 23/4.

42) The given equation is $$ w - \frac{1}{3} = \frac{5}{12}$

$\implies w = \frac{5}{12} - \frac{1}{3}$

$w = \frac{5}{12} - \frac{4}{12}$

$w = \frac{1}{12}$

The answer is 1/12.

Answer:

Measure of angle B: 76°

Measure of angle C: 76°

Measure of angle A: 28°

Step-by-step explanation:

Equations

Let's call

x = measure of angle B

Since angle B is congruent with angle C:

x = measure of angle C

The sum of the angles in a triangle is 180°:

180 - x - x = 180 - 2x = measure of angle A

It's given the measure of angle B is 20 more than twice the measure of angle A, thus:

x = 20 + 2(180 - 2x)

Operating the parentheses:

x = 20 + 360 - 4x

Adding 4x:

5x = 380

Dividing by 5:

x = 380/5

x = 76°

Measure of angle B: 76°

Measure of angle C: 76°

Measure of angle A: 180 - 2*76°= 28°
