Answer:

x = 15 ft

Step-by-step explanation:

Triangle ACD is similar to triangle ABE based on the information given, therefore we can set up a proportion to compare the sides:

side AE / side EB = side AD / side DC

4/6 = 10/x

Solve for x

x = (10)(6) / 4

x = 60 / 4

x = 15 ft

Answers

Answer:

y = 10

x = 17

Step-by-step explanation:

4y - 3 = 37

4y = 37 + 3

4y = 40

y = 40 / 4

y = 10

3x - 9 = 42

3x = 42 + 9

3x = 51

x = 51 / 3

x = 17

Hope that helps!

Answer:

x = 17

y = 10

Step-by-step explanation:

Parallel sides are equal in length, so set them equal to each other.

3x - 9 = 42 --> Add 9 to both sides.

3x = 51 --> Divide both sides by 3.

x = 17

4y - 3 = 37 --> Add 3 to both sides.

4y = 40 --> Divide both sides by 4.

y = 10

The area of a rectangle can be represented by the expression
x^2+2x-3
If the dimensions of the rectangle are known to be the factors of the expression, write each dimension of this rectangle as a binomial. (Write the two binomial factors that you are mulitplying together to get the area).

Answers

Answer:

I believethe answers are (x-1)(x+3)

Step-by-step explanation:

What is the vertex of the function h(x) = (x+ 6 + 3? O A. (-6,-3) O B. (-6,3) OC. (6,3) OD. (6,-3)​

Answers

Answer:

The vertex is ( -6, 3)

Step-by-step explanation:

h(x) = |x+ 6| + 3

Inside the absolute value is the h or the x coordinate of the vertex

Outside is the k or the y value of the vertex

It is in the form

h(x) = |x-h| + k  where (h,k) is the vertex

h(x) = |x - -6| + 3

The vertex is ( -6, 3)

Answer:

B. (-6, 3)

Step-by-step explanation:

Given function:

h(x) = |x + 6| + 3

This is the translation of f(x) = |x|,  6 units left and 3 units up

So the vertex is (-6, 3)

Correct choice is B

then a = and b = .

Answers

Answer:

a = 0, b = -15

Step-by-step explanation:

Given the following complex number;

x1 = 3(cosπ+isinπ)

x2 = 5(cosπ/2 - isinπ/2)

x1x2 = 15(cosπcosπ/2 - icosπsinπ/2+isinπcosπ/2 -i²sinπsinπ/2)

x1x2 = 15(0 - i(-1)+0 -0)

x1x2 = 15(-i)

x1x2 = -15i

x1x2 = 0-15i

Since

0 - 15i = a+ bi

Compare

a = 0

-15-  = bi

b = -15

Hence a = 0, b = -15

A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 different colours?

Answers

Answer:

Question:

A bag with 2 blue (B), 4 red (R) and 5 green (G) marbles (total 11 marbles).

Two are drawn at random without replacement.

Find probability of getting two marbles of same colour.

Solution:

We can get either 2B, 2R or 2G as successful outcomes.

To get two blue marbles (2B),

probability of the first one being blue = P(B)=2/11

probability of the second blue marble = P(-B)=1/10 (one left out of 10 left)

Probability that both are blue (use multiplication rule)

P(2B)=(2/11)(1/10)=2/110

Similarly, for two red marbles

P(2R)=(4/11)(3/10)=12/110

and for two green marbles

P(2G)=(5/11)(4/10)=20/110

Since all three events 2B, 2R and 2G are mutually exclusive, the probability

that any one can happen is the sum of the individual probabilities, thus

probability of getting two marbles of the same colour (without replacement)

=P(2B)+P(2R)+P(2G)

=2/110 + 12/110 + 20/110

=34/110

= 17/55

Answers

Either B or C. They look exactly the same but I can’t tell because the photo is blurry

y intercept is 75 and x intercept is 75/2.5=30

The graph of the equation y = -25x + 75 is attached.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Since the pool is 75 feet long, hence b = 75. Also the swimmer travels 2.5 feet per second to the other side, hence m = -25

The equation becomes:

y = -25x + 75
