So, when x = -10.

If you notice, -10 is NOT in the domain (the domain is (-3,13))

so, there is no solution.

Answer: -24

Step-by-step explanation:

Step one :

For the first equation

Given that x=-10

F(x) =2x-4 if 3<x<10

x exists in this domain

Substituting x in the equation we have

F(-10)=2(-10)-4

F(-10)= -20-4

F(-10)=-24

Step two :

For the second equation

Given that x=-10

F(x) =x²-+3 if 10<=x<13

x does not exist in this domain

Prices increase by approximately 18.17% in a year if they rise at a monthly rate of 1.4%.

The given monthly rate of 1.4% can be represented as 1.014 in decimal form (1 + 0.014).

To calculate the total increase over a year, we need to compound this monthly rate for 12 months since there are 12 months in a year. We can use the formula for compound interest to find the overall increase:[tex]\[A = P(1 + r)^n\][/tex]

Where:

[tex]\(A\)[/tex] = the final amount after [tex]\(n\)[/tex] periods (in this case, a year),

[tex]\(P\)[/tex] = the initial price (100% or 1 in decimal form, as it's the starting point),

[tex]\(r\)[/tex] = the monthly rate in decimal form (1.4% or 0.014), and

[tex]\(n\)[/tex] = the number of periods (12 months).

Plugging in the values:

[tex]\[A = 1 \times (1 + 0.014)^{12}\][/tex]

[tex]\[A = 1 \times 1.1771\][/tex]

[tex]\[A \approx 1.1771\][/tex]

The final amount [tex](\(A\))[/tex] represents the price increase over the year. To express this as a percentage, we subtract 1 from [tex]\(A\)[/tex] and then multiply by 100:

[tex]\[Price \, Increase \, Percentage = (A - 1) \times 100\][/tex]

[tex]\[Price \, Increase \, Percentage = (1.1771 - 1) \times 100\][/tex]

[tex]\[Price \, Increase \, Percentage \approx 18.17\%\][/tex]

Therefore, prices increase by approximately 18.17% in a year if they rise at a monthly rate of 1.4%.

One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).

Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.

The unit rate is 2,86:2,50

The correct answer is:

D. No, because [tex]\(-5^2\)[/tex] equals -25 and [tex]\((-5)^2\)[/tex] equals 25.

To evaluate the expression [tex]\( -5^2 \)[/tex] and [tex]\( (-5)^2 \)[/tex], we need to understand the order of operations.

According to the order of operations (PEMDAS/BODMAS), exponentiation takes precedence over negation.

So, [tex]\( -5^2 \)[/tex] means [tex]\( -(5^2) \)[/tex], which equals -25.

On the other hand, [tex]\( (-5)^2 \)[/tex] means [tex]\( (-5) \times (-5) \)[/tex], which equals 25.

Therefore, [tex]\( -5^2 \)[/tex] is not equal to [tex]\( (-5)^2 \)[/tex].

The correct answer is option D.

Answer:

The solution is 0.022.

Step-by-step explanation:

Given that,

[tex]\dfrac{0.86}{5}-0.3\times0.5[/tex]

We need to solve the equation

Using PEMDAS rule

On dividing 0.86 by 5

[tex]0.172-0.3\times0.5[/tex]

On multiply 0.3 from 0.5

[tex]0.172-0.15[/tex]

On subtract 0.15 from 0.172

[tex]0.022[/tex]

Hence, The solution is 0.022.

Answer:

You can watch 13 movies

Step-by-step explanation:

Cost of Carl's Cable Company:

Cost of Teleview Cable Company

Lets take that you watch [tex]x[/tex] paper view movies per month.

Then the cost of paper view movies = $[tex]4*x[/tex]

Now we can calculate the total cost of cable TV if you watch [tex]x[/tex] paper view movies per month.

Total cost = Monthly service + Paper view movie cost

                 =[tex]55+4x[/tex]

Now we can write an inequality for the Cost of Car's Cable Company cost being less than Teleview as follows;

[tex]55+4x≤110[/tex]

Now we can solve this inequality and find [tex]x[/tex] the number of movies you can watch so that the Cost of Carl's cable company will be less than teleview.

[tex]55+4x≤110[/tex]

=[tex]4x≤110-55[/tex]

=[tex]4x≤55[/tex]

=[tex]x≤13.75[/tex]

Therefore, if you watch less than 13.75 movies per month the cost of Carl's cable company cost will be less than Teleview.

So you can watch 13 movies (Number of movies has to be a whole number)

The answer you are looking for is M = -18.

To find this answer, you first distribute 9 into the parenthesis (m + 4). Once you've distributed, you should be left with 9m + 36 = 7m. Next, you subtract 9m from both sides. This will give you 36 = -2m. Finally, divide both sides by 2. Thus giving you a final answer of M = -18.

Hey there!

To solve this, we will first replace x with 5 anytime we see it in the equation.

f(5) = 2^5

Now, we simplify 2^5.

The base is 2 and the exponent is 5 in this case.

The exponent is the number of times you multiply the base by itself. In oour case:

2 x 2 x 2 x 2 x 2 = 32

f(5) = 32

Step-by-step explanation:

I just did it

The scale factor is determined by the ratio of the lengths of corresponding sides of two similar figures. To find QY, divide QY' by the scale factor.

The scale factor is the ratio of the lengths of corresponding sides of two similar figures. In this case, line WY and line W'Y' are similar figures, and the scale factor is determined by the ratio of their lengths. The scale factor can be calculated by dividing the length of W'Y' by the length of WY. Given that QY' = 4.125, the scale factor can be determined by dividing QY' by QY. So, the scale factor is 4.125/QY. To solve for QY, divide QY' by the scale factor: QY = QY'/scale factor. Therefore, QY = 4.125/(4.125/QY) = (4.125*QY)/4.125 = QY.

Answer:

Step-by-step explanation:

given that diameter of the pipe = 14 inches

radius = 7 inches

Length =2156 inches

Pipe is in the form of a cylinder

Volume of cylinder = pi r^2 h

where r = radius and h = l = 2156

We have to substitute the values of r and h.

Let us take pi as 22/7

= 22/7 (7)(7)(2156)

Cancel out 7 and multiply the remaining 22 ,7 and 2156

=332024 cubic inches

4.2 feet = 50.4 inches

Answer:

I did this on a Calc. but it is 6.666667

Step-by-step explanation:

Calculator

To divide 20 by 3, we use long division. The quotient is 6 remainder 2, or 6.67 as a decimal.

To divide 20 by 3, we can use long division. The divisor, 3, goes into the first digit of the dividend, 2, once. We then multiply 3 by 1, which equals 3, and subtract that from 2. The remainder is 2. We bring down the next digit, 0, and the divisor goes into 20 six times. We then multiply 3 by 6, which equals 18, and subtract that from 20. The remainder is 2. Since there is no longer a digit to bring down, we have our final answer: 20 divided by 3 equals 6 remainder 2, or 6.67 as a decimal.

To find H(6) for the function H(x) = 5(x - 6), substitute 6 for x, resulting in H(6) = 5(6 - 6) = 5(0) = 0.

The question asks for the evaluation of H(6) when H(x) = 5(x - 6). To find H(6), we simply substitute 6 in place of x in the function and calculate the result.

H(6) = 5(6 - 6)

Calculating the expression within the parentheses:

6 - 6 = 0

Now multiply by 5:

5 times 0 = 0

Therefore, H(6) = 0.
