Answer:

17 x + 28

Step-by-step explanation:

Simplify the following:

2 (x + 5) + 3 (5 x + 6)

Hint: | Distribute 2 over x + 5.

2 (x + 5) = 2 x + 10:

10 + 2 x + 3 (5 x + 6)

Hint: | Distribute 3 over 5 x + 6.

3 (5 x + 6) = 15 x + 18:

10 + 2 x + 18 + 15 x

Hint: | Group like terms in 10 + 2 x + 18 + 15 x.

Grouping like terms, 10 + 2 x + 18 + 15 x = (2 x + 15 x) + (10 + 18):

(2 x + 15 x) + (10 + 18)

Hint: | Add like terms in 2 x + 15 x.

2 x + 15 x = 17 x:

17 x + (10 + 18)

Hint: | Evaluate 10 + 18 using long addition.

| 1 | 8

+ | 1 | 0

Answer:

A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.

Answer:

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].

Answer:

  D.  The ball was thrown from an initial height of 3 feet.

Step-by-step explanation:

The generic form of the equation for (vertical) ballistic motion is ...

  [tex]h(t)=-\dfrac{1}{2}gt^2+v_0t+h_0[/tex]

where g is the acceleration due to gravity, usually approximated as 32 ft/s², v₀ is the initial upward velocity, and h₀ is the initial height.

The given equation matches the situation where the object was launched vertically at the rate of 40 ft/s from a height of 3 ft.

The 3 represents an initial height of 3 feet.

Answer:

D. 20 yds

Step-by-step explanation:

✔️First, find the distance across across the pond on the drawing using Pythagorean Theorem:

Distance across = √(6² + 8²) = √100

Distance across on drawing = 10 in.

✔️Next, find the actual distance using the scale of 1 inch : 2 yards:

The scale implies that,

1 inch represents 2 yards

Therefore:

10 inches will represent = 10 × 2 = 20 yards

Explanation:

1) 2x^2 -5x -3 = 0 . . . . standard form equation

To convert this to factored form, you can look for factors of the product (2)(-3) that have a sum of -5. It can help to start by listing the ways that -6 can be factored. Since we want the sum of factors to be negative, we want to have larger negative factors.

  -6 = (1)(-6) = (2)(-3)

The sums of these factor pairs are -5 (what we want) and -1 (not relevant). We can call these factors p=1 and q=-6.

If a = 2 is the leading coefficient of our standard form quadratic, we want to use these factors in the form ...

  (ax +p)(ax +q)/a . . . . . factored form of the quadratic

  (2x +1)(2x +(-6))/2 . . . .fill in the values we know

  (2x +1)(x -3) . . . . . . .  factor 2 from the second binomial

So, the factored form of the quadratic equation is ...

  (2x +1)(x -3) = 0 . . . . factored form equation

__

2) f(x) = x^2 +7x +10 . . . . standard form quadratic function

Using the thinking process described above, we are looking for factors of 10 that have a sum of 7. We know those are 2 and 5. So, the factored form of the function is ...

  f(x) = (x +2)(x +5) . . . . . . factored form quadratic function

The leading coefficient is 1, so we have no further work to do.

Roots, x-intercepts, zeros

The graph attached below shows this function crosses the x-axis when x=-2 and x = -5. These values of x are variously called "roots", "x-intercepts", and "zeros" of the function. They are values for which the factors and the function are zero. (x+2=0 when x=-2, for example)

Solutions

Often, we are interested in solving the equation ...

  f(x) = 0

For that equation, the solutions are the zeros or x-intercepts or roots. The graph attached also shows solutions for ...

  f(x) = 4

Those solutions are x = -6 and x = -1. The function value is not zero for these values of x, so the roots, x-intercepts, or zeros are not solutions to this equation.

Answer:

[tex]\boxed {\boxed {\sf B. \ \frac{8}{13} }}[/tex]

Step-by-step explanation:

Probability is found by dividing the number of favorable outcomes by the total number of outcomes.

[tex]P= \frac{favorable \ outcomes}{total \ outcomes}[/tex]

For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.

The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).

[tex]P(blue \ or \ green) = \frac{8}{13}[/tex]

This fraction cannot be reduced, so the probability of selecting a blue or green marble is 8/13.

Answer:

$1840.00

Step-by-step explanation:

The answer is 1840.00 because the formula for a trapezoid is A=a+b

divided by 2, then multiply by height, so, you did that on one half of the trapezoid, then the result, x2. After that, you multiply the result by 4 since each square foot of the carpet costs $4. Then, the result would be 1840.00.

Hope this helps! :)

Answer:

A. SinA=10/26 B. CosA=24/26 C. TanA=10/24 D. TanB=24/10

Step-by-step explanation:

You really need to remember this formula for trig: Soh Cah Toa

S=Sin       O=Opposite H=Hypotenuse

C=Cosine A=Adjacent H= Hypot.

T=Tangent O= Oppo. A=Adjac.

Now if we take Soh, what it basically means is that the sine is equal to the opposite over the hypotenuse, same thing for the others, cosine is equal to the adjacent over the hypotenuse and tangent is equal to the opposite over adjacent. When you have a letter such as A or B in front of sin cos or tan, it represents which angle on the triangle does this imply to, if that makes sense. For example, for sin A you use Soh to find the ratio, opposite = 10 and hypotenuse = 26, so 10/26. Same thing for Cos A, adjacent = 24 and hypotenuse = 26. You apply the same thing for tan, but something happened, there is a TAN B, so what that means is that you go to angle B, and you apply the toa formula, opposite= 24 and adjacent = 10 so 24/10. Hope this answers your question. MAKE SURE YOU REDUCE YOUR RATIOS. :)

( it might be wrong pls dont report me just let me kno y its wrong )

Answer:

8.6

Step-by-step explanation:

First of all consider the thousands in the decimal which is 2. Since 2 is not greater than 5 we have to remove the number 2 and 3 from the 8.6023.

We're left with 8.60. Now we see that there's a 0 in the hundredths so since it's not greater than 5 we remove it.

Now we're left with 8.6 which is to the nearest tenth.

Answer:

−4

Step-by-step explanation

Answer:

−4

Step-by-step explanation:

-6 x (1/3 + 1/3)

Since 1/3 and 1/3 have the same denominator, add them by adding their numerators.

-6 x (1+1/3)

Add 1 and 1 to get 2.

-6 x (2/3)

Express -6 x (2/3) as a single fraction.

-6 x 2/3

Multiply −6 and 2 to get −12.

-12/3

Divide −12 by 3 to get −4.

−4

Answer:

12

therefore;

number of 1/4 cups needed = 3x4=12

Answer:

The bear population after t years will be:

p(t) = 380,000*(1 + 0.025)^t

Step-by-step explanation:

Here the question is missing, so i will found an equation that can tell us the bear population as a function of the number of years that have passed since 2015, represented with the variable t.

The initial bear population in Canada was 380,000.

Each year the population increases by a 2.5%

Then after one year, the population is:

p(1) = 380,000 + 380,000*(2.5%/100%)

p(1) = 380,000 + 380,000*(0.025) = 380,000*(1 + 0.025)

After another year the population increases by 2.5% again, then the new population will be:

p(2) = 380,000*(1 + 0.025) +  380,000*(1 + 0.025)*(2.5%/100%)

p(2) =  380,000*(1 + 0.025) +  380,000*(1 + 0.025)*(0.025)

p(2) = 380,000*(1 + 0.025)*(1 + 0.025)

p(2) = 380,000*(1 + 0.025)^2

So we already can see the pattern here, the bear population after t years will be:

p(t) = 380,000*(1 + 0.025)^t
