Answer:

27.89feet

Step-by-step explanation:

Given the following

Length of the ladder = 32foot = hypotenuse

Angle of elevation = 29.37°

Required

Distance of the building from the base of the ladder (adjacent)

Using the SOH CAH TOA identity

Cos theta = adj/hyp

Cos 29.37° = d/32

d = 32cos29.37°

d = 32(0.8715)

d = 27.89 feet

Hence the required distance is 27.89feet

Answer:

27.89 feet

Answer:

3 ; 5/2

Step-by-step explanation:

Δ= 121 - 120 = 1

x1 = (11 + 1)/4 = 3

x2 = (11-1)/4 =5/2

The solution of the quadratic equation is x = 3 and x = 5/2. Options B and D are correct.

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The given qudratic equation is,

2x² — 11x + 15 = 0

The values of the zeroes of a qudratic equation are calculated by the formula written below,

[tex]x = \dfrac{(-b \pm \sqrt{(b^{2} - 4ac)})} { (2a)}[/tex]

The solution can be calculated as,

[tex]x = \dfrac{(-(-11) \pm \sqrt{((-11)^2 - 4(2)(15))})} {(2(2))}\\x = \dfrac{(11 \pm \sqrt{(121 - 120)})} { 4}\\x = \dfrac{(11 \pm 1)} { 4}[/tex]

Hence, the value of x will be 3 and 5/2 for the given quadratic equation.

Answer:

79.2 units

Step-by-step explanation:

Tangents to a circle from an external point are congruent , then

PQ = 27.4

QR = 5.9 + 12.2 = 18.1

PR = 12.2 + (27.4 - 5.9 ) = 12.2 + 21.5 = 33.7

Then

perimeter = PQ + QR + PR = 27.4 + 18.1 + 33.7 = 79.2

You deposit $4000 in an account earning 4% interest compounded monthly. After 15 years, you will have approximately $7224.44 in the account.

To calculate the future value of an account with compound interest, we can use the formula:

Future Value = Principal * (1 + (Interest Rate / Number of Compounding Periods))^(Number of Compounding Periods * Time)

In this case, the principal (initial deposit) is $4000, the interest rate is 4% (or 0.04 as a decimal), and the compounding is done monthly, so there are 12 compounding periods in a year.

Substituting these values into the formula, we have:

Future Value = $4000 * (1 + (0.04 / 12))^(12 * 15)

Calculating this expression gives us:

Future Value ≈ $4000 * (1.003333)^180

Future Value ≈ $4000 * 1.806111

Future Value ≈ $7224.44

After 15 years, you will have approximately $7224.44 in the account, considering the given interest rate and compounding frequency.

Answer:

Step-by-step explanation:

Answer:

PQ = 31

QR = 31

PR = 47

Step-by-step explanation:

From the question, we have the vertex as Q

This means that we have the legs as PQ and QR; with PR as the base

The base angles of an isosceles triangle are equal and that means that the leg length values are equal

So, QR = PQ

Thus;

3x-2 = 5x-24

5x-3x = 24-2

2x = 22

x = 22/2

x = 11

So we have PQ as;

5(11) - 24 = 55-24 = 31

QR = 3(11) -2 = 33-2 = 31

PR = 5x-8 = 5(11)-8 = 55-8 = 47

BC=48 degrees, AD= ??

Step-by-step explanation:

I'm going to find the angle BC so a full circle is 360 degrees but half of a circle is 180 degrees since we are dealing with half a circle its 180, 90 and 42 are already used so lets add these two numbers which is 132 lastly to find out the remaining which is angle BC we have to subtract 180-132 which is 48. So your first answer is 48.

Next is AD which i don't know how to do, Sorry :(

Answer:

6885.1 yd^3

Step-by-step explanation:

the shape in the attached image is a sphere.

thus, we are to find the volume of a sphere

Volume = 4/3 nr^3

n = 22/7

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

radius = 23.6/2 = 11.8 ft

4/3 x 22/7 x 11,8^3 = 6885.1 yd^3

Answer:

51, 52, 53

Step-by-step explanation:

51, 52, and 53 are all greater than 50, but less than 54

The possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

Number systems are mathematical systems that are used to express numbers in various ways.

Given that the number is "greater than 50 and less than 54", which means it must be strictly between those two values.

Here, the range of numbers that Adam could have written is (50, 54), which means any number greater than 50 and less than 54, but not including 50 and 54 themselves.

Thus, the possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.
