Answer:

A. F(x)is an even function so both ends of the graph go in the same direction.

D. The leading coefficient is negative so the left end of the graph goes down.

Step-by-step explanation:

Even function:

For every value of x, f(x) = f(-x)

In this question:

We are given the following function:

[tex]f(x) = -4x^6 + 6x^2 - 52[/tex]

Testing if it is even:

[tex]f(1) = -4(1)^6 + 6(1)^2 - 52 = -4 + 6 - 52 = -50[/tex]

[tex]f(-1) = -4(-1)^6 + 6(-1)^2 - 52 = -4 + 6 - 52 = -50[/tex]

Since f(1) = f(-1), it is even.

Since it is even, both ends of the graph go in the same direction, so option A is correct, while option B is wrong.

Options C and D:

The leading coefficient, is -4(which multiplies x with the highest exponent). Since it is negative, it goes to negative infinity as x increases, that is, the left end goes down, and option D is correct while C is not.

Answer:

32

Step-by-step explanation:

Hello, in (16^5)^1/4, you would multiply the exponents together like this:

16^5 x 1/4= 16^5/4

The exponents multiplied make 5/4. Now you need to multiply 16 with 5/4 like this:

16 x 5/4= 80/4

80 divided by 4 is 32 so therefore, the answer is 32.

Answer:

Options (1), (2), (3) and (4)

Step-by-step explanation:

By applying the sine and cosine rules in the given triangle,

sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(30°) = [tex]\frac{AC}{AB}[/tex]

              = [tex]\frac{11\sqrt{3} }{22}[/tex]

              = [tex]\frac{\sqrt{3}}{2}[/tex]

sin(30°) = [tex]\frac{BC}{AB}[/tex]

             = [tex]\frac{11}{22}[/tex]

             = [tex]\frac{1}{2}[/tex]

cos(60°) = [tex]\frac{BC}{AB}[/tex]

              = [tex]\frac{11}{22}[/tex]

              = [tex]\frac{1}{2}[/tex]

sin(60°) = = [tex]\frac{AC}{AB}[/tex]

              = [tex]\frac{11\sqrt{3} }{22}[/tex]

              = [tex]\frac{\sqrt{3}}{2}[/tex]

Options (1), (2), (3) and (4) are the correct options.

Answer:

If the interval is 1 < x < 3, then you are examining the points (1,4) and (3,16). From the first point, let a = 1, and f (a) = 4. From the second point, let b = 3 and f (b) = 16. The average rate of change is 6 over 1, or just 6.

The average rate of change is [tex]\frac{6}{25}[/tex]

'When we calculate average rate of change of a function over a given interval, we’re calculating the average number of units that the function moves up or down, per unit along the x-axis. We could also say that we’re measuring how much change occurs in our function’s value per unit on the x-axis.'

According to the given problem,

Rate of change formula = [tex]\frac{f(b) - f(a)}{b-a}[/tex]

y = log3x

⇒ a= 1

   b= 3

Therefore,

⇒ [tex]\frac{log(3*3) - log(3*1)}{3-1}[/tex]

⇒ [tex]\frac{log9 - log3}{2}[/tex]

⇒[tex]\frac{1}{2}[/tex] log[tex](\frac{9}{3})[/tex]

⇒ [tex]\frac{1}{2}[/tex] * log 3

⇒ [tex]\frac{6}{25}[/tex]

Hence we can conclude the rate of change as [tex]\frac{6}{25}[/tex]

Answer:

4.09

Step-by-step explanation:

Hope it helps. That is the answer

The partial product of 3.4 x 1.2 is (3 + 0.4) x (1 + 0.2).

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

3.4 x 1.2

3.4 is equal to 3 + 0.4.

1.2 is equal to 1 + 0.2.

Now,

(3 + 0.4) x (1 + 0.2)

= 3 + 0.6 + 0.4 + 0.08

= 3 + 1 + 0.08

= 4 + 0.08

= 4.08

Thus,

3.4 x 1.2 is equal to (3 + 0.4) x (1 + 0.2).

106 - 8h = 34

Whenever a math question says "when h = 9," they mean you substitute this number where h is in the equation.

106 - 8(9) = 34

106 - 72 = 34

34 = 34

This means the fact that h = 9 is a solution for h.

Hello. I hope this helps!

Let's set up an equation for this.

1st table = 83 cm

2nd table = 90 cm OR 0.9 m

3rd table = x

Total length = 250

Equation:

83 + 90 + x = 250

Now we'll solve the equation.

83 + 90 + x = 250

173 + x = 250

x = 250 - 173

x = 77 cm

Answer:

1335.7

Step-by-step explanation:

f(5)= 9e^x

Substitute x for 5 and solve

The value of the equation f ( x ) = 9eˣ , when x = 5 is  1335.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be f ( x ) = 9eˣ

The equation is an exponential form , and the value of x is substituted in the equation

When the value of x is 5

The value of e = 2.7182

x = 5

So , substituting the value of x in f ( x ) , we get

f ( x ) = 9eˣ

f ( 5 ) = 9 x e⁵

Now , e⁵ = 148.4131

And ,

The equation f ( 5 ) = 9 x 148.4131

                                = 1335.718

                                ≈ 1335.7

Hence , the value of the equation f ( x ) = 9eˣ , when x = 5 is  1335.7

Answer:

x=5

∠ABD = 33

∠A = 115

Step-by-step explanation:

Once again here are the properties of a trapezoid:

Opposite angles are congruent

Opposite side lengths are congruent

And here is a property of a triangle:

the measure of the angles add up to equal 180

Given this information we need to find

x, ∠ABD and ∠A

First lets find x

Remember opposite side lengths are congruent

Segment AD and segment BC are opposite side lengths ( which are congruent)

That being said we create an equation to solve for x

2x = 10

step 1 divide each side by 2

2x/2=x

10/2=5

we're left with x = 5

Now lets find ∠A

∠C and ∠A are opposite angles

so ∠C≅∠A

Because ∠C = 115 ∠A also = 115

Finally lets find ∠ABD

because ∠BDC and ∠ABD are opposite angles we can find the measure of ∠BDC and get the value of ∠ABD

ΔBDC is a triangle formed within the parallelogram

That being said we can find the measure of ∠BDC using the triangle angle rule (stated previously)

That the measures of the angles in a triangle add up to equal 180

So we can find the missing angle (∠BDC) by subtracting the given angles ( which have a measure of 32 and 115) from 180

∠BDC = 180 - 32 - 115

180 - 32 - 115 = 33

so ∠BDC = 33

Meaning that ∠ABD also = 33
