Answer:

Step-by-step explanation:

5*10*2=100

8*10/2=40

12*4*2=96

12*5=60

4*5*2=40

100+40+40+96+60=336cm²

The surface area for the given composite figure is 442 cm²

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Given is a composite figure, composed of a triangular prism and rectangular prism, attached to each other.

We will find the surface area of the composite figure by adding surface areas of both the solids and subtracting the common base area from it.

We know that, surface area of a triangular prism and rectangular prism, are S = bh+(b1+b2+b3)l and 2(lh+wh+lw) respectively.

Therefore, SA = 12(8)+(12+10+8)5 +2(12×5+4×5+12×4) - lw

= 96+150+2(60+20+48) - 12×5

= 246+256-60

= 442

Hence, The surface area for the given composite figure is 442 cm²

Answer:

Slope: 2; Y-Intercept: (0,3)

Step-by-step explanation:

As you can see from the graph, it rises 4 and runs 2. So, the slope is 2. It intersects the y axis at (0,3)

Answer:

Slope: 3/2

Y-intercept: 3

Step-by-step explanation:

The line passes the y-axis at 3, and to find the slope you use rise over run. Our rise (which is going up) is 3, and our run (which is going across) is 2 (and since it moves from left to right, it is positive). The slope would be 3/2.

The maximum number of relative extrema of the given polynomial is; 3

When trying to find the maximum number of relative extrema of a polynomial, we usually use the formula;

Maximum number of relative extrema contained in a polynomial = degree of this polynomial - 1.

We are given the Polynomial as;

f(x) = 3x⁴ - x² + 4x - 2

Now, the degree of the Polynomial would be 4. Thus;

The value of sin(∝) is -√56/15

The given parameter is:

cos(∝) = -13/15

To determine the sine, we use the following identity

sin^2(∝) = 1 - cos^2(∝)

So, we have:

sin^2(∝) = 1 - (-13/15)^2

This gives

sin^2(∝) = 1 - 169/225

Evaluate the difference

sin^2(∝) = 56/225

Take the square root of both sides

sin(∝) = ±√56/15

sin(∝) is negative in quadrant III.

So, we have:

sin(∝) = -√56/15

Hence, the value of sin(∝) is -√56/15

Answer:

7.5 m           457.5[tex]\pi[/tex] [tex]m^{2}[/tex]

Step-by-step explanation:

First, visualize the original cone and the smaller cone as overlapping similar triangles. The scale factor of the original cone to the smaller cone is 50:40, so if the smaller cone has a radius of 6 m, then the radius of the original cone would be 7.5 m.

The volume of the frustum is the volume of the original cone minus the volume of the smaller cone. The formula for the volume of a cone is V = [tex]\frac{1}{3} \pi r^{2}h[/tex].

Original Cone = [tex]\frac{1}{3} \pi r^{2}h[/tex] = [tex]\frac{1}{3} \pi *7.5^{2}*50[/tex] = 937.5[tex]\pi[/tex]

Smaller Cone = [tex]\frac{1}{3} \pi r^{2}h[/tex] =  [tex]\frac{1}{3} \pi *6^{2}*40[/tex] = 480[tex]\pi[/tex]

Frustum = 937.5[tex]\pi[/tex] - 480[tex]\pi[/tex] = 457.5[tex]\pi[/tex]

The real rate of return formula exists utilized, and we use the data given in the exercise to the formula to estimate the real rate of return.

The real rate of return exists at 2.926%.

The real rate of return formula exists utilized, and we use the data given in the exercise to the formula to estimate the real rate of return.

The formula for the real rate of return:

R = (1+N)/(1+i) - 1

Where, N exists the nominal rate and i exists the inflation rate, as decimals.

A certificate of deposit offers a nominal interest rate of 5.5 percent annually.

This means that N = 0.055

Inflation exists 2.5 percent

i = 0.025

Substitute the values in the above equation, we get

[tex]$R = [(1+0.055)/(1+0.025)] -1[/tex]

= [1.055/1.025] - 1

Step-by-step explanation:

No. of points got from 1 stunt = 50.

No. of points deducted from 1 fail = 40.

6 stunts and 9 falls were gained last week.

So, A/C the number of points earned =

(6×50)-(9×40)

= 300 - 360

= -60

Her score today is 3 times her score from last week so multiply by 3

= (-60) × 3

= -180

If it were multiplied by -3 instead of 3 it would be...

(-60) × (-3)

= 180

The difference would be that on multiplying with positive 3 she would be 180 points in the whole but multiplying with negative three means she is 180 points in the league.

The similarity is that that whole number is same but the symbol adds a difference and the absolute value would be same too.

If f(x) = 2x + 3 then Δy/Δx = 2 and g(x) = 2² +3 then Δy/Δx = 2.33.

The correct answer is option A.

f(x) has a rate of change of 2

g(x) has a rate of change of 2.33

So g(x) is growing faster

Let f(x) = 2x + 3 and g(x) = 2² +3

Let, ∆y /∆x denotes the ratio of y change and x change when x change exists relatively large.

If f(x) = 2x + 3

Δy/Δx = [f(3) - f(0)]/3 - 0

f(3) [tex]= 2*3+3 = 9[/tex]

f(0) [tex]= 2*0+3 = 3[/tex]

[f(3) - f(0)]/3 - 0 = (9 - 3)/3

The term that describes the situation is called: stabilizing selection.

Unlike disruptive selection (diversifying selection) that tends to favor extreme traits when changes occur, stabilizing selection is defined as changes in population genetics in which extreme traits are not favored, rather, traits that are of intermediate variants are most favored and selected for.

Stabilizing selection can simply be described as the exact opposite of disruptive selection.

In the scenario given, traits of producing fewer starlings or more are extreme traits that are not favored and have reduced fitness.

By definition and properties of the absolute value used on the quadratic equation we conclude that F(|- 4|) = 12.

Herein we must apply the definition of absolute value prior to evaluating the quadratic equation defined in the statement. From algebra we know that absolute values are defined as:

|x| = x, when x ≥ 0 or - x, when x < 0. (1)

Then, we apply (1) on the quadratic equation:

F(|x|) = |x|² - 2 · |x| + 4

As x < 0, by absolute value properties:

F(|x|) = x² + 2 · x + 4

F(|- 4|) = (- 4)² + 2 · (- 4) + 4

F(|- 4|) = 16 - 8 + 4

Given the ratio of the profit share between the business partners Mr. Jake and Mr. Sebastian as 3:2, and the total profit as 24,000, the profit share received by Mr. Jake is 14,400.

The ratio of the shares of business partners Mr. Jake to Mr. Sebastian given to us is 3:2.

So we assume Mr. Jake's share of profit to be 3x, and Mr. Sebastian's share of profit to be 2x.

Thus, the total profit between them is 3x + 2x = 5x.

The total profit given is 24,000.

Thus, we get an equation:

5x = 24000,

or, x = 24000/5 = 4800.

Thus, the share of profit Mr. Jake receives is 3x = 3*4800 = 14400.
