Answer:

[tex] \frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y[/tex]

Step-by-step explanation:

We know that [tex] { \tan }^{2} y = { \sec }^{2} y - 1[/tex]

Also , [tex] { \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y } [/tex]

So ,

[tex] \frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y[/tex]

Answer:

4x + 8

Step-by-step explanation:

1. 4(2x + 4) Multiply 2x by 4 to get 8x. Multiply 4 by 4 to get 16. You should now have the equation 8x + 16 / 2.

2. Divide the 8x and 16 by 2. You should get 4x and 8. (4x + 8).

Given :  −3 + 5 + 6g = 11 − 3g

To find :  The variable g

Solution:

Isolate and solve for the variable g in the equation −3 + 5 + 6g = 11 − 3g

Steps:

−3 + 5 + 6g = 11 − 3g

2 + 6g = 11 − 3g

6g = −3g + 9

9g = 9

g = 1

Hence,

Answer: g = 1

Answer:

The correct answer is B, 42.

Step-by-step explanation:

In order to know the answer to the given question, the following logical reasoning has to be made:

The multiple number of 7 that is less than 45 but greater than 40 is 42. This is so since 42 is the result of multiplying 7 by 6 (7 x 6 = 42). In turn, 7 multiplied by 5 is equal to 35 (7 x 5 = 35), which does not exceed the number 40, while 7 multiplied by 7 is equal to 49, which is not less than 45 (7 x 7 = 49).

Answer:

she worked a total of 20 hours

Answer:

h = 21

Step-by-step explanation:

10h + 15 = 225

10h + 15 - 15 = 225 - 15

10h = 210

10 ÷ 10h = 210 ÷ 10

h = 21

Answer:

it's C

Step-by-step explanation:

You have to plug in the inputs into the n variable to get your answer/output.

Answer:

Step-by-step explanation:

f(n)= 3n+2

hence

1) for n= -2  

f(-2) = 3(-2)+2 =-6+2= -4

2) for n= -1

f(-1) = 3(-1)+2 =-1

3) for n=0

f(0)=3(0)+2 = 2

4) for n=1

f(1) =3(1)+2 =5

5) for n=2

f(2)=3(2)+2 =8

Hence  "C" option is correct

Answer:

The equations are not given but the clue to your answer is given below:

Step-by-step explanation:

So the question above talks generally about differential equations (equations whose derivatives can be found) and then describes them thus - the order of a differential equation and the linearity status of a differential equation.

To determine whether or not each of the absent equations is linear, check for the following characteristics of linearity:

1. The maximum number or power that any variable in a linear equation is raised to is 1.

Example: 2x² + 6y = 43y is NOT a linear equation because some or all (in this case, variable x) of the variables in it are raised to a power greater than 1. Variable x is raised to the power of 2.

2. An equation (a linear equation, in this case) contains an 'equal to' sign. This is the reason why it's called an equation. There is a mathematical expression on each side of the equal to sign. Take note of this, just incase one of the options in your question has no equal to sign.

Example: 2x + 6y is NOT a linear equation. It is a linear expression. It contains no equal to sign that compares two distinct mathematical expressions.

3. A linear equation usually has not more than two variables. It is not complex or difficult to solve.

Example: 2x + 6y = 43z is NOT a linear equation.

I think it would be D not sure tho hope this is helpful

Answer:

B

Step-by-step explanation:

The correct answer is B because in A and C, the gray area is not under the blue line since y has to be less than the equation. It is not D because the equation does not have a negative slope and in this inequality, it is also not equal to. Because the line in D is not a dotted line, then you know it is also equal to.

Step-by-step explanation:

Step-by-step explanation:

(x + 8)²

= (x + 8)(x + 8)

= x² + 2(x)(8) + 8²

= x² + 16x + 64.

The binomial expression (x + 8)² is converted into trinomial in standard form x² + 16x + 64.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The expression is given below.

⇒ (x + 8)²

Simplify the expression, then we have

⇒ (x + 8)²

⇒ x² + 8² + 2·8·x

⇒ x² + 16x + 64

The binomial expression (x + 8)² is converted into trinomial in standard form x² + 16x + 64.

Answer:

64 model cars.

Step-by-step explanation:

What we know.

Cory has 80 cars in his collection.

That is 25% more than Everett has.

We can deduce that the equation would be c = 1.25e.

So, how do we figure out e?

Well, 1.25 is the same as 5/4.

So, find the reciprocal of 5/4 and multiply by 80.

4/5 * 80 = e

64 = e
