Step-by-step explanation:

-6 + 4a = 18

4a= 24

a=6

!!!!!!!!!!!!

Answer:

OC) 6

Step-by-step explanation:

Transpose -6 to the other side

-6 + 4a = 18

4a = 18+6

4a = 24

a = 6

Your first differential equation is incomplete, so I'll just look at the second one.

y' + 2xy = 4x

Multiply both sides by exp(x ²):

exp(x ²) y' + 2x exp(x ²) y = 4x exp(x ²)

The left side is the derivative of a product:

(exp(x ²) y )' = 4x exp(x ²)

Integrate both sides:

exp(x ²) y = ∫ 4x exp(x ²) dx

For the integral, substitute u = x ² and du = 2x dx :

exp(x ²) y = 2 ∫ exp(u) du

Solve for y :

exp(x ²) y = 2 exp(u) + C

exp(x ²) y = 2 exp(x ²) + C

y = 2 + C exp(-x ²)

Answer:

x = 58-x-6

x = 58-6-x

x = 52-x

x+x = 52

2x = 52

x= 52/2

x = 26

58-26

= 32

Large number = 32

Small number = 26

Answer:

Area of rectangle = l*b

11*9

99

I think it will help you.

Answer:

first is rectangle

L = 11 m

W = 9m

area = LW

area = 11 × 9

area = 99 sq.m

2nd is circle

D = 21 .6

r = 1/2 × 21.6

r = 10.8

area = 22/7 ×10.8²

area = 336.582 sq.

3rd triangle

B = 8 in

H = 4.6 in

area = 1/2 × 8 × 4.6

area = 18.4 sq.in

4th parallelogram

b = 12 in

h = 3 in

area = b × h

area = 12 × 13

area = 156 sq.in

5th trapezoid

h = 7cm

b1 = 4 cm

b2 = 10 cm

area = ½ ×7 (4 + 10

area =49 sq.cm

Answer:

  (a)  vertical compression by a factor of 1/3

Step-by-step explanation:

We can see that g(x) = 1/3f(x). Multiplying a function by a constant scales the graph vertically by that factor. When the magnitude of the factor is more than 1, we say the graph is "stretched." When it is less than 1, we say the graph is "compressed" by that factor.

Here, the scale factor is 1/3, so the graph is "vertically compressed by a factor of 1/3."

_____

Additional comment

My personal preference is for compression to be described by the factor the graph is divided by. I would call g(x) a compression of f(x) by a factor of 3. Modern curriculum authors disagree, calling it compression by a factor of 1/3.

Be careful. Using the currently accepted language, a stretch is always by a number larger than 1, and a compression is always by a number less than 1. This rules out choices C and D simply on the basis of the language used.

__

For many graphs, vertical scaling and horizontal scaling can be interchanged. We note that g(x) is wider than f(x), so could be stretched horizontally by some factor. That factor would be √3. The equation using a horizontal stretch factor would be g(x) = (x/√3)^2. Replacing x by x/k is a stretch by a factor of k in the horizontal direction.

Answer:

5/8

Step-by-step explanation:

First, find how many slices are yellow or blue.

There are 2 yellow slices and 3 blue slices, so 5 of them are either yellow or blue.

There is a total of 8 slices.

So, the probability that it will stop on a yellow or blue slice is 5/8.

Answer:

-6

Step-by-step explanation:

Move the variable to the left hand side and change its sign.

5 - 2x + 4x = -7

Collect like terms.

- 2x + 4x = - 7 - 5

2x = - 7 - 5

Calculate the difference.

2x = -12

Divide both sides.

x = -6

Answer:

The z-distribution should be used for this problem.

Step-by-step explanation:

The population distribution is assumed to be normal. Which distribution to use?

If we have the standard deviation for the sample, we use the t-distribution.

If we use the standard deviation for the population, we use the z-distribution.

There is a known standard deviation of 2.2 minutes.

This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.

Answer:

$200 each.

Step-by-step explanation:

You are sharing the $600 bonus with 2 of your kids, meaning that the money will be evenly divided between 3 people. Divide the total amount of money with the total amount of people:

$600/3 persons = $200/person

Each person obtains $200.

The circumcenter is the center of the circle that contains the vertices of a triangle

When a triangle is inscribed in a circle, the vertices of the triangle touch the circumference of the circle

A line drawn through the center of the circle and passes through each of the triangle vertex is its circumcenter.

Hence, the name of the required point is the circumcenter

Answer:

Thus the function g is the function f stretched vertically by a factor 5.

Step-by-step explanation:

Multiplication of a function by a constant:

When a function is multiplied by a constant a > 1, the function is stretched vertically by a factor of 5.

In this question:

f(x) = x^2

g(x) = 5x^2

Thus the function g is the function f stretched vertically by a factor 5.

Answer:

A. (-2.28, 3.38)

Step-by-step explanation:

The confidence interval of the slope :

b ± Tcritical*SE

Tcritical at 95%, df = n - 2 = (15 - 2) = 13

Tcritical = 2.160369

b = slope Coefficient = 0.54924

S.E = 1.311

Hence, we have :

Confidence interval = 0.54924 ± (2.160369 * 1.311)

Confidence interval = 0.54924 ± 2.832243759

Lower boundary = 0.54924 - 2.83224 = - 2.283

Upper boundary = 0.54924 + 2.83224 = 3.3814

The answer option is A. (-2.28, 3.38)
