Answer:

A

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

given diameter = 14 then r = 14 ÷ 2 = 7

A = π × 7² = 49π m²

Answer:

49π

Step-by-step explanation:

area of circle=pie*radius²

and radius=diameter/2

therefore

r=14/2

=7m

Area =π*7²

Area=49π

The total value of the loan with the quarterly compounded interest

is $117599.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

The formula for compound interest compounded quarterly is,

A = P(1 + (r/4)/100)⁴ⁿ.

[tex]A = 50000(1 + 6.15/100)^{4\times\frac{43}{12}}[/tex].

[tex]A = 5000(1 + 0.0615)^{14.33}[/tex].

[tex]A = 5000(1.0615)^{14.33}[/tex].

[tex]A = 5000\times2.352[/tex].

A = $117,599.

Probability that both donators are O blood type = 0.0203

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x.

The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Given,

A group of 46 people where 7 of them are O blood type

Probability of one donator to be O blood type

= No. of People with O blood type/total People in the group

= 7/46

No. of people left in the group left after choosing one donator = 46 - 1 = 45

No. of People left with O Blood type = 7 - 1 = 6

Probability of 2nd donator to be O blood type = 6/45

Probability that both are O blood type = 7/46 × 6/45

                                                                = 42/2070

                                                                = 0.0203

Hence, there is probability of 0.0203 that both donators are of O blood type.

Answer: The real part of the complex number is 0.

Step-by-step explanation:

Complex numbers are always in the format: a + bi

On the given complex number, -i√5 , it is representing the "bi" part of the standard complex number expression.

We are looking for the real part. The real part is the real number. Since -i√5 doesn't show a real part, we can infer that its real part is 0.

If you rewrite the expression with 0 as the real number, it is equivalent to the principle of the original:

0 + -i√5

This concept is similar to the idea:

y = mx + b

if the equation said:

y = 3x

we know that b is 0, although its not stated. This principle is used in complex numbers.

Thank you.

The equations of the functions are

Function (a)

From the question, we have the following parameters that can be used in our computation:

x-intercepts = (4, 0) and (-2, 0)

This means that

y = a(x - 4)(x + 2)

Also, we have point (5, -7)

This means that

a(5 - 4)(5 + 2) = -7

So, we have

a =  -7

The equation becomes

y = -7(x - 4)(x + 2) --- in standard form

In vertex form, it is

y = -7(x - 1)^2 + 63

To test the point (2, 15), we have

y = -7(2 - 1)^2 + 63

Evaluate

y = 56 ---- false

Function (b)

From the question, we have the following parameters that can be used in our computation:

x-intercepts = (5, 0) and (-5, 0)

This means that

y = a(x - 5)(x + 5)

Also, we have point (-4, -36)

This means that

a(-4 - 5)(-4 + 5) = 36

So, we have

a =  4

The equation becomes

The requried area of 3 of the pieces is 231 square feet. Option B is correct.

The area of a circle is the amount of space enclosed by the circle in a two-dimensional plane. It is given by the formula:

A = πr²

where "A" is the area of the circle, "r" is the radius of the circle, and "π" (pi) is a mathematical constant with an approximate value of 3.14159.

Here,
The area of a full circle with a radius of 14 feet is given by:

A = πr²

A = (22/7) × (14)²

A = (22/7) × 196

A = 616 square feet (rounded to the nearest whole number)

If the circle is cut into 8 equal pieces, each piece will have an area of:

616 ÷ 8 = 77 square feet

Therefore, 3 pieces will have an area of 3 × 77 = 231 square feet.

Thus, the requried area of 3 of the pieces is 231 square feet. Option B is correct.

9 miles for every ½ hour and 6 miles for every 20 minutes can be considered equivalent because they represent the same speed, just measured in different units.

To see this, we can convert the units to a common unit, such as miles per hour.

First, let's convert the 6 miles in 20 minutes to miles per hour:

[tex] \frac{6}{20} \times 60[/tex]= 18 miles/hour

Next, let's compare this speed to the 9 miles per ½ hour:

[tex] \frac{9}{ \frac{1}{2} } = \frac{9}{ \frac{1}{2} } \times \frac{1}{ \frac{1}{2} } = 18[/tex]

Since both speeds are equal to 18 miles per hour, we can conclude that they are equivalent. This means that the missing values are also equivalent.

Answer:

ok one doll is 3 dollars and one purse is 6 dollars

and for the bottom I got 84 so I don't know I'm sorry

Step-by-step explanation:

Answer:

1. The unit price for a doll is three dollars. The unit price for a purse is six dollars.

2. One doll costs three. One purse costs six.

3. Polly spends $24 on the 2 dolls and 3 purses.

Step-by-step explanation:

Doing some calculations, 1 doll costs three dollars and 1 purse costs six dollars.

5 x 3 + 6 = 21

7 x 3 + 1  = 27

If Polly buys 2 dolls and 3 purses, that means she spends six dollars on the dolls and eighteen dollars on the purses.

(2 x 3) + (3 x 6) = $24

Polly spends $24 on 2 dolls and 3 purses.

The correct measures of these two angles are, 30°  and 150°.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

here, we have,

He also wants the measure of ∠A to be five times the measure of ∠D.

Let the smaller side is x then other side is 5x,

so, we get,

x+5x=180°[interior property]

on solving we get

6x=180°

x=30°

therefore, the other side is 5x

Answer:

8.  TN = 22 units

9.  RT = √(165) units

Step-by-step explanation:

It appears that point T is the circumcenter of triangle MNP.

A circumcenter of a triangle is:

As a perpendicular bisector is a line that divides another line segment into two equal parts at a right angle, then:

As point T is the circumcenter, ΔMTN, ΔNTP and ΔMTP are isosceles triangles and MT, TP and TN are the radius of the circumcircle.

Therefore:

To find the length of TN, find the value of x by equating the given expressions for MP and TP:

[tex]\implies \sf MT = TP[/tex]

[tex]\implies 6x - 56 = 3x - 17[/tex]

[tex]\implies 3x = 39[/tex]

[tex]\implies x = 13[/tex]

Substitute the found value of x into the expression for TP:

[tex]\implies \textsf{TP} = 3(13) - 17[/tex]

[tex]\implies \textsf{TP} = 22[/tex]

Therefore, as TN = TP then TN = 22 units.

First find the value of x by equating the given expressions for TN and TP:

[tex]\implies \sf TN=TP[/tex]

[tex]\implies 4x-17=x+10[/tex]

[tex]\implies 3x=27[/tex]

[tex]\implies x=9[/tex]

Substitute the found value of x into the expression for TN:

[tex]\implies \textsf{TN} = 4(9) - 17[/tex]

[tex]\implies \textsf{TN} = 19[/tex]

As RT is the perpendicular bisector of MN, then ΔTRN is a right triangle where ∠TRN is 90°.

Given:

To calculate the length of RT, use Pythagoras Theorem:

[tex]\implies \sf RN^2+RT^2=TN^2[/tex]

[tex]\implies \sf RT=\sqrt{TN^2-RN^2}[/tex]

[tex]\implies \sf RT=\sqrt{19^2-14^2}[/tex]

[tex]\implies \sf RT=\sqrt{165}[/tex]

The measure of angle W in the kite WXYZ is 115°

A kite is a quadrilateral with reflection symmetry across a diagonal. Because of this symmetry, a kite has two equal angles and two pairs of adjacent equal-length sides.

Given that, In kite WXYZ, m ∠ x = 90° and m ∠ z =40°.

Please refer to figure attached,

We know that, in a kite, it has two opposite and equal angles.

According to figure, here,

m ∠ W = m ∠ Y

Let m ∠ W = m ∠ Y = x

Also, the sum of interior angles of quadrilateral = 360°

Therefore,

x + x + 90° + 40° = 360°

2x = 360° - 130°

2x = 230°

x = 115°

Thus, m ∠ W = m ∠ Y = 115°  

Hence, the measure of angle W in the kite WXYZ is 115°

Answer:

600 cm²

Step-by-step explanation:

let x = length of a side of the cube

all sides are equal in a cube

Volume = x³ = 1000 cm³

x = ∛1000 = 10 cm

Area of 1 side = 10cm x 10cm = 100 cm²

There are 6 equal sides in a cube

SA = 6(100) =  600 cm²

When x is 4, the output of the equation is greater.

The value for x that produces the same output in both the graph and the equation is equal to 6.
