Answer:

B) 44

Step-by-step explanation:

Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:

2.5*5.5=13.75

Then to solve for the square, it is also (B*H):

5.5*5.5=30.25

At this point, to solve for the total area, you just add the areas together:

13.75+30.25=44

Hope this helps!

Answer: B. 44

Step-by-step explanation: The area of a rhombus is base times height. The height is 5.5 cm, and the base is 8 cm. To find the base, add 2.5 and 5.5.

8 x 5.5 = 44

The area is 44 cm^2

Answer:

3^2 = 9

9+2 = 11

g(3)= 11

Step-by-step explanation:

ANSWER

[tex]g(3) = 11[/tex]

EXPLANATION

The given function is

[tex]g(x) = {x}^{2} + 2[/tex]

We substitute b x=3 into the function to obtain;

[tex]g(3) = {3}^{2} + 2[/tex]

Simplify;

[tex]g(3) = 9 + 2[/tex]

[tex]g(3) = 11[/tex]

Answer:

It actually really depends on the size of the apples, say 1 pound of aan apple should be approx 3 medium-sized apples, so maybe for 3 pounds of an apple it would be around 9 medium sized apples.

Answer:

h(-8) = 22

Step-by-step explanation:

Plug  -8 in for t and simplify...

h(-8) = 2(-8 + 5)² + 4

    h(-8) = 2(-3)² + 4

        h(-8) = 2(9) + 4

          h(-8) = 18 + 4

             h(-8) = 22

Answer:

Step-by-step explanation:

Given h(f)=-2(t+5)^2 +4

There is an intermediate step which is

h(f) = -2(f + 5)^2 + 4

h(-8) = -2(-8 + 5)^2 + 4

h(-8) = -2(-3)^2 + 4

h(-8) = -2(9) + 4

h(-8) = -18 + 4

h(-8) = - 14

Answer:

The answer to this is B, because supplementary angles sum up to 180 degrees, which means it is a straight angle.

Answer:

Option B and D

Step-by-step explanation:

Given are four options and we have to select the one which form a straight angle.

The given options are

A. Vertical Angles  ... Vertical angles are formed when two lines intersect and hence cannot combine to form a straight angle.  Incorrect option.

B. Supplementary Angles ... Supplementary angles are a pair of angles which add upto 180 degrees and hence they form a straight angle. Correct option

C. Complementary Angles  ... These pair add up to 90 degrees and cannot combine to form a straight angle.  ..  Incorrect

D. Linear Pair ... A linear pair is a pair of angles formed on a straight line and hence correct option.

ANSWER

y=x

y=x³

EXPLANATION

A function, f(x) has an inverse if and only if

[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]

Thus, the function is one to one.

For y=x or

[tex]f(x) = x[/tex]

[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]

Hence this function has an inverse.

For the function y=x² or f(x)=x².

[tex]f(a) = f(b) \Rightarrow \: {a}^{2} = {b}^{2} \Rightarrow \: a = \pm \: b[/tex]

This function has no inverse on the entire real numbers.

For the function y=x³ or f(x)=x³

[tex]f(a) = f(b) \Rightarrow \: {a}^{3} = {b}^{3} \Rightarrow \: a = b[/tex]

This function also has an inverse.

For y=x⁴ or f(x) =x⁴

[tex]f(a) = f(b) \Rightarrow \: {a}^{4} = {b}^{4} \Rightarrow \: a = \pm \: b[/tex]

This function has no inverse over the entire real numbers.

Answer:

The function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.

Step-by-step explanation:

Function inverse definition:

If a provided function f(x) is mapped x to y, then the inverse of the provided function f(x) is mapped y to x.

Or  [tex]f(x)=f(y)\Rightarrow x=y[/tex]

Now, consider the function y = x.

Interchange the variables x and y.

[tex]x=y[/tex]

Now, solve [tex]x=y[/tex] for [tex]y[/tex].

[tex]x=y[/tex]

Therefore, this function has an inverse.

Consider the function [tex]y=x^{2}[/tex].

Interchange the variables x and y.

[tex]x=y^{2}[/tex]

Now, solve [tex]x=y^{2}[/tex] for [tex]y[/tex].

[tex]\pm \sqrt{x} =y[/tex]

Therefore, the function has no inverse.

Consider the function [tex]y=x^{3}[/tex].

Interchange the variables x and y.

[tex]x=y^{3}[/tex]

Now, solve [tex]x=y^{3}[/tex] for [tex]y[/tex].

[tex]\sqrt[3]{x}=y[/tex]

Therefore, the function has inverse.

Consider the function [tex]y=x^{4}[/tex].

Interchange the variables x and y.

[tex]x=y^{4}[/tex]

Now, solve [tex]x=y^{4}[/tex] for [tex]y[/tex].

[tex]\pm \sqrt[4]{x}=y[/tex]

Therefore, the function has no inverse.

Hence, the function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.

Answer: [tex]g(x)=\frac{1}{9}x^2[/tex]

Step-by-step explanation:

By definition, he quadratic parent function [tex]f(x)=x^2[/tex] is the simplest form of a quadratic function.

By definition, if the fucntion is multiplied by the factor b and:

 |b|>0  the function is stretched.

If 0<|b|<1 the function is compressed.

Then the new function will have the form:

[tex]g(x)=(\frac{1}{b}x)^2[/tex]

Therefore, keeping the above on mind, if b=3, then the new function is:

[tex]g(x)=(\frac{1}{3}x)^2[/tex]

[tex]g(x)=\frac{1}{9}x^2[/tex]

Answer: g(x)=(1/3(x))^2

Step-by-step explanation:

pythagoras

a^2 = b^2 + c^2

a^2 = (8)^2 + (4)^2

a^2 = 64 + 16

a^2 = 80

[tex]a = \sqrt{80} [/tex]

Answer:

The length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Step-by-step explanation:

We are given the length (l) = 8, width (w) = 4 and height (h) = 2.

Now we have to find the diagonal of the base.

The given figure is a rectangle box. The base of the rectangular box is a rectangle with the length (l) = 8 and the width(w) = 4

The length of the diagonal (d) = [tex]\sqrt{l^2 + w^2}[/tex]

d = [tex]\sqrt{8^2 + 4^2}[/tex]

d = [tex]\sqrt{64 + 16}[/tex]

d = [tex]\sqrt{80}[/tex]

d = [tex]\sqrt{16} \sqrt{5}[/tex]

d = 4[tex]\sqrt{5}[/tex]

So, the length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Answer:

5 cm

Step-by-step explanation:

If AB is tangent to the circle k(O), then radius OB is perpendicular to segment AB.

If BC is tangent to the circle k(O), then radius OC is perpendicular to segment AC.

Consider two right triangles ABO and ACO. In these triangles:

By HL theorem, triangles ABO and ACO are congruent. Then

Hence, ∠BAC=∠OAB+∠OAC=30°+30°=60°.

Consider triangle ABC, this triangle is isosceles triangle. In isosceles triangles angles adjacent to the base are congruent, thus

∠CBA=∠BCA=1/2(180°-60°)=60°.

Therefore, triangle ABC is an equilateral triangle, so BC=AB=AC=5 cm.

I think none of these are right. It's Y=-5/3x +4/3

ANSWER

[tex] - \frac{5}{3} [/tex]

EXPLANATION

The given line has equation

[tex]3y + 5x = 4[/tex]

Rewrite the equation in the form:

[tex]y = mx + b[/tex]

Add -5x to both sides.

[tex]3y + 5x - 5x = - 5x + 4[/tex]

[tex]3y = - 5x + 4[/tex]

Divide through by 3.

[tex]y = - \frac{5}{3}x + \frac{4}{3} [/tex]

Comparing to the slope intercept formula,

[tex]m = - \frac{5}{3} [/tex]

The slope is

[tex] - \frac{5}{3} [/tex]

Multiply the previous value by 2

Step-by-step explanation:

As the exponents increase,

(that is, they go from negative to positive)

-5,-4,-3,-2, -1,0

We see that each previous value is multiplied by a factor of 2

We can see the graph of the values in the picture below

Answer:

206  2/3 ft³

Step-by-step explanation:

The volume of this solid is given by V = (1/3)(base area)(height).

Here, V = (1/3) (62 ft²) (10 ft ) = 206  2/3 ft³

Three times two equals six

Another factor of 6, besides 6 and 1, is 3. Factors are numbers that divide into another number without leaving any remainder. Both 2 and 3 are factors of 6 since 2 multiplied by 3 equals 6.

Besides 6 and 1, another factor of 6 is 3.

Factors are whole numbers that divide evenly into another number. For the number 6, the factors are 1, 2, 3, and 6. The process of factoring involves finding all numbers that you can multiply together to get the number in question. In this case, 2 multiplied by 3 equals 6.

We can also verify this by noting that dividing 6 by 3 gives us 2 with no remainder, confirming that 3 is indeed a factor of 6.

Answer:

The Answer is 156

Step-by-step explanation:

A=(B1+B2)H/2

1) to find the area of a trapezoid you must First add the 2 bases

20+32= 52

2) Then Multiply the 2 bases sum by the Height

52 x 6 = 312

3) divide the product 312 By 2

312/2= 156

That is Your answer!

Hopes this helps!

For the area of a trapezoid use formula: Area = (BaseX+BaseY) times Height divided by 2.

so for this problem you’d plug in (20+32) times 6 then divide it by two.

20+32=52 times 6 equals 312

Divide by 2 and you get 156.

Area= 156
