Answer:

No. The slope of Line E is 3/2, and the slope of Line D is 6/8.

Step-by-step explanation:

For line E, let's find two points that the lines go through: (0,4) and (30, 24).

m=30-0/24-4

m=30/20

m= 3/2 or 1.5

Line E does not have a slope of 3.

Line D goes through these two points: (8,9) and (16,15).

m=15-9/16-8

m=6/8 or 0.75

Line D doesn't have a slope of 3.

The equivalent rational expressions with denominator (2u  - 3)(x + 1)(u - 4);

[tex]\frac{5}{(2u - 3)(u + 1)} , \frac{3u}{(2u-3)(u-4)}[/tex]

We want to rewrite the rational expression;

Now, the denominator 2u² - u - 3;

From online factorization calculator, the factors of 2u² - u - 3 are;

(2u - 3) and (u + 1)

Similarly, the denominator (2u² - 11u + 12);

From online factorization calculator, the factors of (2u² - 11u + 12) are;

(2u - 3) and (u - 4)

Answer:

The answer to this question is 9cm^2, the second answer

Step-by-step explanation:

To find the area of this parallelogram, you have to first find the area of one of the two triangles shown. The formula to solve a triangle is (base * height)/2, so that would be 4.5cm^2 for each triangle, times two for two triangles would be 9cm^2. If you wanted to do it an easier way, just multiply the length of the bottom of the parallelogram with the height. The measures telling you 3.5 are telling you the length of the diagonal line, so don't pay attention to that.

Answer:

4y^2-24y+36

Step-by-step explanation:

Expand the expression to simplify, which you do by using the FOIL method, then combining like terms.

(a-b)(a-b) = a^2 - 2ab + b^2

(2y-6)^2

= (2y-6)(2y-6)

= 4y^2 - 12y + 36

Step-by-step explanation:

The domain of the exponential function can take values is option (B) all real numbers is the correct answer.

Exponential function involves exponents. An exponential function is an function with exponents where the exponent (or) a part of the exponent is a variable. The population increase or decrease can be modeled as exponential function.

For the given situation,

In 1990, Jamaica's initial population,P₀ = 2,466,000

Rate of population growth,r = 1.1% = 0.011

Let x be the number of years

Then the population growth can be written as

[tex]P(x)=P_{0}(1+r)^{x}[/tex] ------- (1)

Now substitute the above values,

⇒ [tex]P(x)=2466000(1+0.011)^{x}[/tex]

For x=0,

⇒ [tex]P(0)=2466000(1+0.011)^{0}[/tex]

⇒ [tex]P(0)=2466000(1)[/tex]

⇒ [tex]P(0)=2466000[/tex]

If we need to find the population growth in future years, we need to use positive values of x.

If we need to find the population growth in past years, we need to use negative values of x.

If we need to find the intermediate values, then we need to use rational numbers.

Hence we can conclude that the domain of the exponential function can take values is option (B) all real numbers is the correct answer.

Explanation:

The horizontal axis always represents the independent variable. Often it is x, but in this case, it's t. The time value does not depend on the height. Time does it's own thing.

The height depends on the time value. The vertical axis, or y axis, is always representing the dependent variable. The notation h(t) helps us see that h must be paired with t, in order to find the value of h so to speak. As the time value changes, so does the height of the ball.

Answer:

For different x values ,we get unique y value. So, Yes the Statement is true that , A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Answer:

We have a data set with 6 whole numbers:

{A, B. C, D, E, F}

The median, in this case, will be the mean of the two middle numbers, C and D.

Median = (C + D)/2 = 40

We also know that the difference between the largest and the smallest number is 21, where the largest number is F and the smallest number is A, then:

F - A  =21.

And the mean will be:

Now we want to take the largest possible numbers such that we end having the largest mean of the whole set, then we can start by taking:

(C + D)/2 = 40

Here we can just take:

C = 39

D = 41

Now our set is:

{A, B, 39, 41, E, F}

Now, A and B should be the largest possible whole numbers (and they must be smaller than 39

The two options are:

B = 38

A = 37

Now our set is:

{37, 38, 39, 41, E, F}

Now, remember that:

F - A = 21

F - 37 = 21

F = 21 + 37 = 58

Then our set will be:

{37, 38, 39, 41, E, 58}

And for E, we should pick the largest number that we could.

In this case, the only restrictions we have for E are that it must be larger than 41, and smaller than 58.

The largest number that meets those conditions is the number 57.

Then our set will be:

{37, 38, 39, 41, 57, 58}

And the mean of this set is:

Mean = (37 + 38 + 39 + 41 + 57 + 58)/6 = 45

use order of operations, PEMDAS.

p(paranthesis), e(exponents), m(multiplication), d(division), s(subtraction).

3 + 3 x (-4) ÷ 2 ÷ (1 - (-5))

so first work with whats in parenthesis

3 + 3 x (-4) ÷ 2 ÷ 6

now, exponents, we dont have any, so move to multiplication.

3 + (-12) ÷ 2 ÷ 6

now, we will do division

3 + (-6) ÷ 6

3 + (-1)

now add

and you get

3. f. $10

4. m. $8

5. h. 79 in²

6. j. 113 in²

Step-by-step explanation:

brailest plz

Hey there, thanks for posting your first question!

If you're asked to factor a polynomial, you need to look for the

greatest common factor between the terms that are involved.

The greatest common factor of 16a and 72 is 8 because 8

is the largest number that can divide into both 16 and 72.

The "a" doesn't qualify because it doesn't appear in every term.

So the 8 factors out.

When that happens, we are left with each term divided by that 8

inside a set of parenthses, I'll show you what I mean.

So we have 8(2a + 9).

I divided the 16a by the 8 and 72 by the 8 and if you

distribute it back you will end up with the original polynomial.

So our answer 8(2a + 9).

Answer:

65.7

Step-by-step explanation:

Given ;

Mean, m = 63.6

Standard deviation, s = 2.5

80th percentile = 80 / 100 = 0.8

The Zscore corresponding to the 80th percentile ; Z < P = 0.842 (Z probability calculator)

Zscore = (x - m) / s

0.842 = (x - 63.6) / 2.5

0.842 * 2.5 = x - 63.6

2.105 = x - 63.6

x = 63.6 + 2.105

x = 65.705
