A rectangular room is 14 feet by 20 feet. The ceiling is 8 feet high. How do you find the length and width of the smaller and larger wall?

Answer:

This is true!

Step-by-step explanation:

P.S: keep in mind that the opposite is not true! If f is continuous at x = c, then f is NOT differentiable at x = c.

:)))

If f is differentiable at x = c, then f is continuous at x = c is not true.

Any point inside the range of a function's purview has a derivative, making it a computable function of one real variable. In these other phrases, each interior site in the domain of an invertible method's graph does indeed have a non-vertical line segment.

F is NOT differentiable at x = c if it is continuous at x = c.

When working with units, this quality is highly helpful since, if a curve is discrete, we automatically infer that it is indeed continuous.

Answer:

[tex]f(-1)>g(-1)[/tex]

Step-by-step explanation:

we are given

[tex]f(x)=-x^2+1[/tex]

We can plug x=-1 and find f(x)

we get

[tex]f(-1)=-(-1)^2+1[/tex]

[tex]f(-1)=-1+1[/tex]

[tex]f(-1)=0[/tex]

now, we can find g(-1)

we can look at the table and find g(-1)

so, we get

[tex]g(-1)=-4[/tex]

we know that

-4 is less than 0

so,

[tex]g(-1)<f(-1)[/tex]

or we get

Answer: 575-d

Step-by-step explanation:

Answer:

[tex](1.12 x 10^5) (6.06 x 10^5) = 6.787 x 10^{10}\\[/tex]

 [tex]\frac{0.5 x 10 ^ 1}{8.14 x 10 ^ 2} = 6.14 * 10 ^ {-3}\\[/tex]

Step-by-step explanation:

To solve this problem we must solve all 4 operations.

For the first one we have:

[tex](1.12 x 10^5) (6.06 x 10^5)[/tex]

When we have multiplication of powers of equal base (10) the same base is placed and the exponents are added

So:

[tex]1.12 * 6.06 x 10^{5+5} = 6.787 x 10^{10}\\[/tex]

Therefore the answer to this question is correct.

For the second question we have:

[tex](2 x 10^1) (3.0 x 10^1)[/tex]

Then following the same procedure as in the previous question we have:

[tex]2 * 3.0 x 10 ^ {1 + 1} = 6 x 10 ^ 2\\[/tex]

Then the answer shown in the statement is not correct, because 10 must be squared, product of the sum of its exponents (1 + 1)

For the third question we have:

[tex](2,775 x 10^{-4}) (4,775 x 10^4)\\2.775 * 4.775 x 10 ^{(- 4) +4} = 13.251 x10 ^ 0\\[/tex]

Then it is verified that the answer for this operation is no correct

[tex]13.25\neq 1.325[/tex]

Finally, for the fourth question we have:

[tex]\frac{5}{(8.14 x 10 ^ 2)}\\[/tex]

This we can write it as:

[tex]\frac{0.5 x 10 ^ 1}{8.14 x 10 ^ 2}\\[/tex]

In division of powers of equal base (10 in this case) the same base is placed and the exponents are subtracted:

[tex]\frac{0.5}{8.14 x 10 ^ {1-2}} = 0.0614 x 10 ^ {-1} = 6.14 * 10 ^ {-3}\\[/tex]

Finally, the problems that show correct answers are:

[tex](1.12 x 10^5) (6.06 x 10^5) = 6.787 x 10^{10}\\[/tex]

[tex]\frac{0.5 x 10 ^ 1}{8.14 x 10 ^ 2} = 6.14 * 10 ^ {-3}\\[/tex]

[tex]\sum^5_{j=1} (5j-12)[/tex] represents the series in sigma notation.

The symbol Σ (sigma) is generally used to denote a sum of multiple terms. This symbol is generally accompanied by an index that varies to encompass all terms that must be considered in the sum.

Given is a series (-7 + (-2) + 3 + 8 + 13), we need to define it in sigma notation,

Therefore,

For j = 1 up to j = 5

j = 1

(5j - 12) = (5(1) - 12) = 5 - 12 = - 7

j = 2

(5j - 12) = (5(2) - 12) = 10 - 12 = - 2

j = 3

(5j - 12) = (5(3) - 12) = 15 - 12 = 3

j = 4

(5j - 12) = (5(4) - 12) = 20 - 12 = 8

j = 5

(5j - 12) = (5(5) - 12) = 25 - 12 = 13

This gives us the given series,

(-7 + (-2) + 3 + 8 + 13)

Hence, [tex]\sum^5_{j=1} (5j-12)[/tex] represents the series in sigma notation.

The problem describes a case of exponential decay. The car's value decreases by 20% each year, so after 5 years of depreciation, the value of the car can be calculated by repeatedly applying this 20% reduction each year. The car will be worth approximately $8,437.76 after 5 years of depreciation.

The problem is a very typical example of exponential decay. The car depreciates in value by 20% each year. This means that after each year, the car is worth 80% (or 0.8) of its value from the previous year. After five years, we can calculate how much the car is worth by simply applying these percentages to the car's initial cost.

To calculate the value of the car after 5 years, you multiply the initial cost of the car by 0.8 (representing the 80% remaining value after depreciation) five times:

So after 5 years, the car will be worth approximately $8,437.76.

Final answer:

To make 3000 pounds of raisins, you would need 12000 pounds of grapes, as it takes 4 pounds of grapes to make 1 pound of raisins.

Explanation:

The question asks us to find out how many pounds of grapes are needed to make 3000 pounds of raisins.

Given that it takes 4 pounds of grapes to make 1 pound of raisins, we can set up a proportion to solve for the total weight of grapes needed. The proportion will be:

4 pounds of grapes / 1 pound of raisins = x pounds of grapes / 3000 pounds of raisins

Multiplying both sides of the proportion by 3000 pounds of raisins gives us:

4 pounds of grapes x 3000 pounds of raisins = x pounds of grapes x 1 pound of raisins

So,

x = 4 x 3000

x = 12000 pounds of grapes.

Therefore, you would need 12000 pounds of grapes to make 3000 pounds of raisins.

Given is a Right Triangular Prism whose height is 8 feet, and whose base is a right triangle with legs 4 feet and 6 feet.

To find the volume of the prism, we must find the area of its base. Its base is in shape of right triangle. We know the formula for area of Right triangle is given as follows :-

[tex] Area = \frac{1}{2} bh \\\\
Area = \frac{1}{2} *4*6 \\\\
Area = \frac{24}{2} \\\\
Area = 12 \;\;feet^{2} [/tex]

So Prism's base area, B = 12 squared feet.

and Prism's height, H = 8 feet.

We know the formula for volume of Prism is given as follows :-

Volume of Prism = (Base Area) x (Height of Prism)

Volume = B x H

Volume = 12 feet² x 8 feet

Volume = 96 feet³

Hence, option C is correct i.e. 96 cubic feet.

Answer:  The length of the hypotenuse is  5√34 units.

Step-by-step explanation:  Given that a right-angled triangle has legs of length 15 ft and 25 ft.

We are to find the length of the hypotenuse.

As shown in the attached figure, AB and BC are the legs of the right-angled triangle ABC. AC is the hypotenuse of the triangle.

Also, AB = 15 ft  and  BC = 25 ft.

From Pythagoras theorem, we have

[tex]AC^2=AB^2+BC^2\\\\\Rightarrow AC^2=(15)^2+(25)^2\\\\\Rightarrow AC^2=225+625\\\\\Rightarrow AC^2=850\\\\\Rightarrow AC=\sqrt{850}\\\\\Rightarrow AC=5\sqrt{34}.[/tex]

Thus, the length of the hypotenuse is 5√34 units.
