Answer:

$1,221

Step-by-step explanation:

0.11×$1,100=$121

$121+ $1100= $1221

If we write the quadratic equation in the vertex form, will be easy to find the vertex.

The vertex form of a quadratic function is:

Where the vertex is (h. k).

We have:

y=(x+2)(x-2)

Form this we conclude: a = 1, h = 0, k = -4. Then:

Answer:

Step-by-step explanation:

Using the compound interest formula to get the equivalent amount after 5 years;

A = P(1+r/n)^nt

P is the principal = 120,000

r is the rate = 10% = 0.1

t is the time = 5 years

n is the time of compounding = 1/2  = 0.5(semi annual interest)

Substitute into the formula;

A = 120,000(1+0.1/0.5)^(5)(0.5)

A = 120,000(1+0.2)^2.5

A = 120,000(1.2)^2.5

A = 120,000(1.5774)

A =  189,292.92

Hence the company issue is $189,292.92

Answer:

5.3 hours

Step-by-step explanation:

Jane can paint the office by herself in 7 hours.

with an associate, she can paint the office in 3 hours.

The combined work rate is 3 hours per office

Required

the work rate for the associate

Step two:

let the expression for the wok rate be

1/A+1/B= 1/T

1/7+1/B=1/3

1/B=1/3-1/7

1/B= 8-4/21

1/B= 4/21

B= 21/4

B=5.3 hours

the work rate for the associate is 5.3 hours

Answer:

y = 1/9 x z^3

Step-by-step explanation:

y is jointly proportional to x and z^3

y = k * x * z^3 where k is the constant of proportionality

y =12, x = 4 and z =3

12 = k * 4 * 3^3

12 = k * 4 * 27

12 = k * 108

12/108 = k

1/9 = k

y = 1/9 x z^3

The value of d that makes (x - d) a factor of p(x) is d = -5.

Given that we need to find the value of d if (x-d) is a factor of the polynomial [tex]\mathrm{p(x)= 2x^3 -dx^2+(1-d^2)x+5}[/tex].

If (x - d) is a factor of the polynomial [tex]\mathrm{p(x)= 2x^3 -dx^2+(1-d^2)x+5}[/tex], it means that if we substitute (x = d) into the polynomial, the result should be equal to zero.

In other words, p(d) = 0.

Let's find the value of d by setting p(d) to zero and solving for d:

[tex]\mathrm{p(d)= 2d^3 -d\cdot d^2+(1-d^2)d+5}[/tex]

To find d, we set p(d) equal to zero:

[tex]\mathrm{ 2d^3 -d\cdot d^2+(1-d^2)d+5 = 0}[/tex]

Now, let's simplify this equation and solve for d:

0 = 2d³ - d³ - d³ + d + 5

0 = 2d³ - 2d³ + d + 5

0 = d + 5

Now, isolate d:

d = -5

So, the value of d that makes (x - d) a factor of p(x) is d = -5.

Answer:

75 degrees.

Step-by-step explanation:

The total number of degrees in a triangle is 180 degrees therefore you can take the sum of the other 2 angles in the triangle and take that number and subtract it from 180.

1). 30+75=105

2).180-105=75

3). using the Side, Side, Side geometry rule, this means that both triangles are the same for all angles and side lengths

4). using the Alternative angle rule, the rule that say that a line that intersects 2 parallel lines forms 4 pairs of similar angles

5). therefore angle ABC is the same as angle BCD

6). Angle ABC was determined to be 75 degrees therefore angle BCD is also 75 degrees

Answer:

8 is the correct answer

Answer:

3 hours from noon, or 3 pm.

Step-by-step explanation:

As of 12 noon, the frequencies are 45 and 60 minutes.

To find out when they leave at the same time again, we need the LCM (least common multiple) of the two frequencies, i.e.

LCM (45, 60) = common time from {45,90,135,180,225,270,315,360....} and{60,120,180,240,300,360,...}

We see that they leave at the same time again at 180 and 360, ... minutes.  Since 180 minutes is the least common multiple, 180 is the next time they leave together again, or 3 hours after noon, i.e. 3pm.

Answer:

The ordered pair (-3, 3) represents the solution of two lines on the coordinate grid.

Thus, option B is true.

Step-by-step explanation:

As we know that the point of intersection of two lines is the solution of the lines.

Given the graph of the lines, we can see that the two lines intersect at the point (-3, 3).

i.e. at x= -3, y = 3

The point of intersection is (-3, 3)

Thus, the ordered pair (-3, 3) represents the solution of two lines on the coordinate grid.

Thus, option B is true.

Answer:

10 mintes

Step-by-step explanation:

Mika would need 10 minutes to eat 35 hot dogs.

Mika can eat 21 hot dogs in 6 minutes. So Mika eats 21 hot dogs/6 minutes

So Mika eats 35 hot dogs/m minutes. The proportion is set up like this:

21/6 = 35/m Then, cross-multiply:

6·35 = 21m

m = 210/21

m = 10 minutes

Answer:

Step-by-step explanation:

3x + 5y = 7

Since that is our original form, let's convert it so that we can find the slope:

5y = -3x + 7

y = -3/5 x + y

To get a perpendicular line, we need the negative reciprocal of the slope. This means that the sign switches and numerator and denominator flip:

m = 5/3

From here, we use the point-slope equation and then convert that into slope-intercept form:

y - y1 = m(x - x1)

y - 6 = 5/3(x - 0)

y - 6 = 5/3x
