A function assigns the value of each element of one set to the other specific element of another set.

A vertical asymptote is the value of x for which the function is not defined.

The vertical asymptotes that the graph of this function F(x)=2/x(x+1) will be 2 because x(x+1) is of the second degree.

Determine the value of x for the following isosceles triangle.

Answers

Given :

▪︎This triangle is an isosceles triangle.

▪︎Measure of one of its legs = 6 inches

▪︎Measure of its equivalent leg [tex] = \tt \frac{x}{9} [/tex] inches

▪︎Measure of its base [tex] = \tt \frac{5}{2} [/tex] inches

Which means :

[tex] =\tt 6 = \frac{x}{9} [/tex]

[tex] =\tt \frac{6}{1} = \frac{x}{9} [/tex]

[tex] =\tt 6 \times 9 = x \times 1[/tex]

[tex]\hookrightarrow\color{plum}\tt 54 = x[/tex]

Let us check whether or not we have found out the correct value of x by placing 54 in the place of x :

[tex] =\tt 6 = \frac{54}{9} [/tex]

[tex] = \tt6 = 6[/tex]

Since the Left Hand Side of the equation is equivalent to the Right Hand Side of the equation, we can conclude that we have found out the correct value of x.

▪︎Therefore, the value of x = 54

Evaluate 6 + a when a = 7. The value is​

Answers

Answer:

13

Step-by-step explanation:

6 + 7 = 13

When a = 7, the value of 6 + a is 13.

To evaluate the expression 6 + a when a = 7, we substitute the value of a into the expression:

6 + a = 6 + 7.

Now, we can simplify the expression by adding the numbers:

6 + 7 = 13.

Explanation:

In the expression 6 + a, the variable a represents an unknown value. By substituting a = 7 into the expression, we replace the variable with its corresponding value.

This allows us to perform the arithmetic calculation to find the result.

Therefore, when a = 7, the value of 6 + a is 13.

What percent of 59 is 44.1? Round the answer to the nearest
hundredth of a percent if necessary.

Answers

Answer:

133.78684807256

Step-by-step explanation:

step 1: We need the assumption that 44.1 is 100% since it is our output value

step 2: We need to represent the value we seek in x

step 3: From step 1, it follows that 100% = 44.1

step 4: In the same vein x% = 59

step 5: This give us a pair of simple equations:

100% = 44.1 (1)

x% = 59 (2)

step 6: by simplify dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

[tex] \frac{100}{x} = \frac{44.1}{59} [/tex]

step 7: Taking the inverse (or reciprocal) of both sides yields

[tex] \frac{x}{100 } = \frac{59}{44.1} [/tex]

= x = 133.78684807256

Therefore, 59 is 133.78684807256% of 44.1

Find the volume of a pyramid with a square base, where the perimeter of the base is 18.5 ft and the height of the pyramid is 7.6 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

Answer:

28.4in³

Step-by-step explanation:

Volume of the square based pyramid = L²H/3 where;

L is the length of a side of the square base

H is the height of the prism

Given

Perimeter of the base = 13.4 in

Height of the pyramid = 7.6in

First we need to get the length of the square base

Perimeter of a square = 4L

13.4 = 4L

L = 13.4/4

L = 3.35 in

Next is to find the required volume of the pyramid

V = L²H/3

V =  3.35²(7.6)/3

V = 85.291/3

V =  28.4 in³

Hence the volume of the pyramid to nearest tenth is 28.4in³

Which equation shows how to rewrite the sum of 30 and 45 using their greatest common factor? 30 + 45 = 5(6 + 9) 30 + 45 = 15(2 + 3) 30 + 45 = 5(6) + 15(3) 30 + 45 = 5(6)(3)

Answers

Answer: 30 + 45 = 15(2 + 3)

Step-by-step explanation:

The greatest common factor for 30 and 45 will be gotten as follows:

Factor of 30 = 2 × 3 × 5

Factor of 45 = 3 × 3 × 5.

GCF = 3× 5 = 15

Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:

30 + 45 = 15(2 + 3)
