Answer:

A. 183.71

Step-by-step explanation:

Original investment in stock plan = $5175

Increase in the first year of investment in stock plan = 9% of $5175

= 0.09 ( $5175)

= $465.75

then new value of investment in stock plan = $5175 + $465.75 = $5640.75

Loss in the investment of stock plan = 5% of $5640.75

= 0.05 ( $5640.75)

= $282.0375

then new value of investment in stock plan = $5640.75 - $282.0375 = $5358.7125

Now let's find difference between latest value and the original value of investment

$5358.7125 - $5175 = $183.7125

Hence choice A. 183.71 is correct.

Answer:

  Initially, the tundra has 180 caribou, and every year , the number of caribou increases by a factor of 1.2 .

Step-by-step explanation:

"Initially" generally means "when t=0." Put 0 where t is in the function and evaluate it:

  f(0) = 1.8(1.2)^0 = 1.8(1) = 1.8 . . . . . hundreds

1.8 hundreds is 1.8×100 = 180.

__

t is in years, so the simplest choice for the second blank in the statement is "year".

__

The exponent of 1.2 is t, which means that 1.2 is a factor of the expression the number of times specified by t.

  for t=0, f(0) = 1.8

  for t=1, f(1) = 1.8(1.2)

  for t=2, f(2) = 1.8(1.2)(1.2)

  for t=3, f(3) = 1.8(1.2)(1.2)(1.2)

Perhaps you can see that every year, the number increases by a factor of 1.2.

_____

You could put "3 years" in the second blank, then the third blank would be 1.2³ = 1.728. While correct, it is probably not what is expected by your answer checker.

Answer:

Answer:

2x+8=20-x

Step-by-step explanation:

if it is an equation you are asking that will be it

2x + 8=20 - x

That is the equation. As you are reading the sentence try writing down exactly what it says. “2 times a number” We know that “times” means multiply, but what are we multiplying. It says to multiply 2 and a number, but we don’t know that number so we call it “x.” Then, it says “plus 8” or add 8. From that information we should come up with the expression 2x + 8. Then, it states “is the same as” which basically means equal to or =. Finally, it states “20 minus the number.” We subtract 20 and the number which can be shown as 20 - x.

All together the equation is written as 2x + 8=20 - x

We can simply do this by writing exactly what the sentence states in the order that it is written.

Answer:

The area of the shaded region is [tex]875.68\ cm^{2}[/tex]

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the large circle minus the area of the inner circle

step 1

Find the radius of the inner circle

we know that

The circumference is equal to

[tex]C=2\pi r[/tex]

we have

[tex]C=77.872\ cm[/tex]

substitute and solve for r

[tex]77.872=2(3.14)r[/tex]

[tex]r=77.872/[2(3.14)]=12.4\ cm[/tex]

step 2

Find the radius of the large circle

[tex]r=12.4+8.4=20.8\ cm[/tex]

step 3

Find the area of the shaded region

[tex]A=(3.14)[20.8^{2} -12.4^{2}]= 875.68\ cm^{2}[/tex]

The area of the shaded region is: 875.60 square centimeters

The formula for the circumference of a circle is:

C = 2πr

where:

C is Circumference

r is radius

We are told the the circumference of the inner circle is 77.872 cm

Thus:

2πr = 77.872

r = 77.872/2π

r = 12.39 cm

Total radius of larger circle = 12.39 + 8.4 = 20.79 cm

Area of larger circle = π * 20.79²

Area of larger circle = 1357.87 cm²

Area of smaller circle is: π *  12.39²

Area of smaller circle is: 482.27 cm²

The area of the shaded region = 1357.87 cm² - 482.27 cm²

The area of the shaded region = 875.60 square centimeters

Final answer:

The expression 3x+10 consists of two terms: 3x (with the coefficient 3) and 10 (the constant).

Explanation:

In the expression 3x+10, there are two terms: 3x and 10. The term 3x consists of a variable (x) and a coefficient (3), which is the number multiplying the variable.

The term 10 is a constant because it does not contain any variables and its value does not change. The coefficients in this expression are therefore the number 3, and the constant is 10.

Answer:

p = 8

Step-by-step explanation:

Subtract 18 from behind the equal sign to cancel it out. This leaves you with 2(p+1)- 18= 0.

Next you'll need to pull out the terms to work with the beginning of the problem. 2(p+1)- 18= 0 would turn into 2p - 16  = 2(p - 8).

This would leave you with 2= 0, but that's not true so continue on to the variable.

So p - 8= 0 making the answer p = 8

Subtract x from each side

8x-x +8 = x-x+3

7x+8 =3

Subtract 8 from each side

7x +8-8 =3-8

7x = -5

Divide each side by 7

7x/7 = -5/7

Step-by-step explanation:

Ok first lets find out what 1/5 of 400 dollars is: 400/5= 80

So 1/5 of 400 is 80, now lets see what 2/5 is= 80 * 2= 160

Then subtract: 400 - 160= 240

we have 240 left. If he spent 1/4 of that on a vacuum cleaner then we have to: 240/4=60

He spent 60 dollars, now to find the remaining we must subtract: 240-60=180

Hope this helped ;)

So 2/5 is 0.4

0.4 of 400=160

400-160=240

240 is the remainder(what is left)

He used 1/4

1/4=0.25

240*1/4 =60

So 240-60=180

So your answer is: Mr.Ray will have $180 left.

Answer:

12/5

Step-by-step explanation:

I doubt that you actually meant If cos0= -5/13 and sin 0<0.  Please use a Greek letter, such as Ф, to represent the angle.

If you'd do this, you'd have:

If cosФ= -5/13 and sin Ф<0

cos Ф and sin Ф are both negative in Quadrant III.

Recall that cos Ф = adj / hyp, and that hyp is always +.  Thus, adj = -5 and hyp = +13.  Using the Pythagorean Theorem to find opp:

opp² + adj² = hyp², or:

opp² = hyp² - adj².  Applying this, we find that opp = -12.

Recall that tan Ф = opp / adj.

Here,

tan Ф = -12 / (-5) = +12/5

Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.

Answer:

Step-by-step explanation:

The solution of the equations 3x + 2y = 13 y = x - 1 will be (3, 2). Then the correct option is B.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The equations are given below.

3x + 2y = 13 ...1

y = x - 1 ...2

Then from the equations 1 and 2, we have

3x + 2(x - 1) = 13

        5x - 2 = 13

             5x = 15

               x = 3

Then the value of y will be

y = x - 1

y = 3 - 1

y = 2

This is a regular pyramid. A regular pyramid is a right pyramid whose base is a regular polygon and whose apex is directly above the centre of the base. The lateral surface area is the sum of the areas of all the lateral faces while  the surface area is the sum of all the lateral faces plus its base. In this exercise, the base is a square so this is also a square pyramid. Next, we have:

LATERAL SURFACE AREA:

For the lateral sides, we have four identical triangles, so the area of a triangle can be found as:

[tex]A=\frac{bh}{2} \\ \\ Where: \\ \\ b:base \\ \\ h:height[/tex]

and the lateral surface will be four times this value:

[tex]S_{L}=4A[/tex]

The base of the triangle is the same as the base of the square. So:

[tex]b=9yd[/tex].

On the other hand, the height of the triangle is the slant height of the pyramid, which is:

[tex]h=10yd[/tex]

So the area of a triangle is:

[tex]A=\frac{(9)(10)}{2} \\ \\ A=45yd^2[/tex]

Therefore:

[tex]S_{L}=4(45)\\ \\ \boxed{S_{L}=180yd^2}[/tex]

SURFACE AREA:

The surface area can be found as:

[tex]S=S_{L}+A_{b} \\ \\ Where: \\ \\ A_{b}: Area \ of \ the \ base \\ \\ S_{L}: Lateral \ surface[/tex]

Calculating the area of the base, which is a square, we have:

[tex]A_{b}=b^2 \\ \\ A_{b}=9^2 \\ \\ A_{b}=81yd^2[/tex]

Therefore:

[tex]S=180+81 \\ \\ \boxed{261yd^2}[/tex]

In this case, we have another similar pyramid compared to the previous one, but we are given the height of the pyramid and we'll name it [tex]H[/tex] in capital letter. We know that the area of a triangle is:

[tex]A=\frac{bh}{2} \\ \\ Where: \\ \\ b:base \\ \\ h:height[/tex]

and the lateral surface will be:

[tex]S_{L}=4A[/tex]

To find [tex]h[/tex], which is the slant height of the pyramid, we need to use the Pythagorean theorem. Next, it is true that:

[tex]h=\sqrt{\left(\frac{b}{2}\right)^2+H^2} \\ \\ b=14 \\ H=12 \\ \\ h=\sqrt{\left(\frac{14}{2}\right)^2+12^2} \therefore h=\sqrt{193}[/tex]

So the area of a triangle is:

[tex]A=\frac{(14)(\sqrt{193})}{2} \\ \\ A=7\sqrt{193}ft^2[/tex]

Therefore:

[tex]S_{L}=4(7\sqrt{193})\\ \\ S_{L}=28\sqrt{193}ft^2 \approx 388.9884[/tex]

Rounding to the nearest tenth:

[tex]\boxed{S_{L}=389.0ft^2}[/tex]

SURFACE AREA:

We know that the surface area can be found as:

[tex]S=S_{L}+A_{b} \\ \\ Where: \\ \\ A_{b}: Area \ of \ the \ base \\ \\ S_{L}: Lateral \ surface[/tex]

Calculating the area of the base, which is a square, we have:

[tex]A_{b}=b^2 \\ \\ A_{b}=14^2 \\ \\ A_{b}=196ft^2[/tex]

Therefore:

[tex]S=28\sqrt{193}+196 \\ \\ S \approx 584.9884ft^2[/tex]

Rounding to the nearest tenth:

[tex]\boxed{S=585ft^2}[/tex]

Here Patrick is making a paper model of castle. He has a net, so he can fold it to build up a pyramid. That's amazing, right? Well, recall that for a pyramid  like that the lateral surface area is the area of the lateral faces, that are all triangles. Thus, for a triangle:

[tex]A=\frac{bh}{2} \\ \\ Where: \\ \\ h: \ slant \ height \ of \ the \ pyramid \\ \\ b: base \ of \ the \ pyramid[/tex]

The slant height of the pyramid is [tex]h=20cm[/tex] because this is the same height of the triangle. On the other hand, the base is [tex]b=15cm[/tex]. So:

[tex]A=\frac{15(20)}{2} \\ \\ h=150cm^2[/tex]

Next the lateral surface area is:

[tex]S_{L}=4(150) \\ \\ \boxed{S_{L}=150cm^2}[/tex]

The method of calculating the area of a polygon depends on the type of polygon. Rectangles and triangles have straightforward calculations, however complex polygons might need to be divided into simpler figures. Certain figures such as circles and ellipses have unique formulas.

Calculating the area of a polygon depends on the type of polygon. For simple regular polygons like a rectangle, area can be found by length x width, for triangles it's base x height / 2. In particular complex polygons, the shape might need to be divided into simpler shapes, and the areas calculated separately.

For a circle, the area A = πr², where r is the radius. If you're trying to find the area of an ellipse, it can be calculated by A = πab, with a and b being half the long and short axis respectively.

The process to determine the area of a frequency polygon is little complex. First, the range of each class interval must be determined, and then multiplied by the frequency of that interval, with these values then being added together.

To find the area of a polygon, you can divide it into smaller shapes with known area and add them up. Alternatively, you can use the formula for the area of a regular polygon.

To find the area of a polygon, you can use different formulas depending on the type of polygon. One general method is to divide the polygon into smaller shapes whose area you know how to calculate, such as triangles or rectangles, and then add up the areas of those shapes. For example, to find the area of a rectangle, you multiply its length by its width.

Another method is to use the formula for the area of a regular polygon, which is given by the formula: Area = 1/2 * ap, where 'a' is the apothem (the distance from the center of the polygon to the middle of one of its sides) and 'p' is the perimeter of the polygon.
