Answer:

C

Step-by-step explanation:

Given

3a - 2a × 4a + 6a

According to order of operations.

Multiplication is performed before addition/ subtraction, thus

= 3a - 8a² + 6a ← collect like terms

= (3a + 6a) - 8a²

= 9a - 8a² → C

Answer:

-1 ± 3i√6

Step-by-step explanation:

Please write this quadratic equation as follows:  x^2 + 2x + 7 = 21.  The " ^ " indicates exponentiation.

The coefficients of this quadratic are 1, 2, 7.

Thus, the "discriminant" b^2 - 4(a)(c) is  (2)^2 - 4(1)(7), or 4 - 28, or -24.

Because the discriminant is negative, this quadratic has two different complex roots:

      -b ± √[ discriminant ]          -2 ± 2i√6      

x = ---------------------------------  =  -----------------  = -1 ± 3i√6

Cos(23)×25 = 23.0126

The distance of the base of the ladder from the wall is 23.01 ft

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We are solving from how far the base of the ladder from the wall and we are representing it as x.

Based on the type of triangle, we are going to use Trigonometry ratios.

We are going to use the cos ratio.

Let opposite be x, base be 25 and theta (angle) be 23.

Cos(23) = x/ 25

Make x the subject;

x = Cos(23)×25

x = 23.0126 ft

Therefore the distance  is 23.01 ft

Answer:

Think of even square roots close to 27: the closest is 25 which has a square root of 5. Now think of the number with an even square root after 25: 36 which has a square root of 6. Since 27 is between 25 and 36, the square root of 27 would be between 5 and 6.

Answer:

3/8

Step-by-step explanation:

We want to evaluate

b - (-1/8) + c

where   b = 2 and   c = -7/4

First, replace b and c values into the expression

2 - (-1/8) + (-7/4)

Then, eliminate the parenthesis

2 + 1/8 - 7/4

Finally, express all terms as fractions with the same denominator, and perform the addition and subtraction

2*8/8 + 1/8 - 7/4 * 2/2

16/8 + 1/8 - 14/8

(16 + 1 - 14)/8

The answer is B -4

Step-by-step explanation:

An inverse function is a function that will “undo” anything that the original function does. For example, if a function takes a to b, then the inverse must take b to a.

Answer:

-4

Step-by-step explanation:

The inverse of a function and the function counteract each other.  The are opposites.  It is like adding and subtracting the same thing.  You end up where you started

Since f(x) and g(x) are inverses

f(g(x) = x

g(f(-4)) = -4

Answer:

x = -2

Step-by-step explanation:

-8 ( x - 3 ) - 4x = 48

Distribute

-8x +24 -4x = 48

Combine like terms

-12x +24 = 48

Subtract 24 from each side

-12x+24-24 = 48-24

-12x = 24

Divide each side by -12

-12x/-12 = 24/-12

x = -2

Answer:

X= -2

Step-by-step explanation:

First, you need to distribute -8 into (x-3) --->  -8(x-3)-4x=48

                                                                         -8x + 24 -4x= 48  

Get numbers with variables on its own side-->     -24         -24

                                                                            -8x - 4x  = 24

Combine -8x and -4x  ----->           -8x-4x = -12x   -12x    = 24

                       Divide ---------------------------------->    -12         -12

                                                                             24÷ -12 = -2

We can subtract 0.75 from both sides. The 0.75 will then cancel out.

[tex]0.5=r[/tex]

r = 0.5

Answer:

r = 0.5
