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.

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

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

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

Answer:

AB = 30 & BD = 16

Step-by-step explanation:

Multiply all sides by two

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:

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

Yes, The statement ''If an event is certain to​ occur, its probability is 1'' is true.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

The statement is,

''If an event is certain to​ occur, its probability is 1.''

Now,

Since, The event that is sure to happen is called a certain event and probability of such an event is 1 as this event is bound to happen.

Thus,  The statement ''If an event is certain to​ occur, its probability is 1'' is true.

Answer:

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 :(
