A. 9B. 9 Square Root Of 2C. 18D. 18 Square Root Of 2

Answers

Answer 1

Answer:

B

Step-by-step explanation:

We are given a right triangle with angles 45, 90, and 45

With this type of right triangle, the ratio of the sides are 1:1:square root of 2

We are also given that the hypotenuse is 18

This means that the sides are in the ratio of x:x:x(square root of 2)

Since 18 is the hypotenuse, we can form the equation of-

18 = x(square root of 2)

18/(square root of 2)=x

x= 9 square root of 2

since y=x, y= 9 square root of 2

ABCD is a square

=> Δ ABD is a  isosceles right triangle at A

using pythago theorem, we have:

AB² + AD² = BD²

=> 2AD² = 4

⇔ AD² = 2

⇒ AD = √2

through O, draw EF parallel to AD and BC

=> EF is  diameter

because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)

=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]

One factor of f(x) = x3 − 14x2 + 61x − 84 is (x − 7). What are the zeros of the function?

Answers

Answer:

-7

Step-by-step explanation:

Because zero is the x, so x=-7 then it's -7

The zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).

What is a polynomial?

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that:

f(x) = x³ − 14x² + 61x − 84

One factor is (x - 7)

The cubic polynomial can be written as:

f(x) = (x - 7)(x² - 8x + 12)

Or

f(x) = (x - 7)(x - 3)(x - 4)

To find the zeroes equate to zero:

f(x) = 0

(x - 7)(x - 3)(x - 4) = 0

x = 7, x = 3, and x = 4

Thus, the zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).

Two angels of a triangle measure 12 and 40.
What is the measure of the third angle of the triangle ?

Answers

Answer:

C) 128

Step-by-step explanation:

Sum of all three angles of triangle = 180

Let the third angle be 'x'

x + 12 + 40 = 180

     x + 52 = 180

             x = 180 - 52

            x = 128

​The perimeter of a triangle is 43 inches. The second side is 4 times as long as the first side. The third side is 1 inch longer than the first side. What is the length of each side

Answers

Answer:

First side=7

Second side =28

Third side =8

explanation:

Perimeter of a triangle is the sum of the length of the sides of the triangle. Given that the perimeter of the triangle = 43 inches

Second side is 4 times the first side

Third side is 1 inch longer the first

Let's call the first side x

Then equation for the perimeter of the triangle is given by

x+4x+x+1=43

We solve for x

6x+1=43

6x=43-1

6x=42

x=42/6

x=7

Therefore the first side x=7, the second side is 4x= 4*7=28, third side= 1+x= 1+7=8

Answers

Answer:

The slope is 0 because it is a straight line

Step-by-step explanation:

Answer:

undefined.

Step-by-step explanation:

You could be really formal and use the slope formula

The y values are both the same -- 4.

The x values are 3.5 and 6.5

Therefore  the slope is (6.5 - 3.5) / (4  -  4)

The denominator is 0

The slope is undefined because 3/0 is not very well behaved.

A horizontal line always gives an undefined amount.

Number of the bags = between 8 and 15  and

1/2 of bags contain money 1/6 of bags contain candy 1/3 of bags contain a toy

As per above the number is divisible by 2, 3 and 6. LCM of the three numbers is 6.

The number between 8 and 15 and divisible by 6:

This number is 6*2 = 12

So the number of bags is 12

the velocity of a falling body varies directly as the time of flight if the velocity of the falling body at the end of two seconds is 64.4ft/s find the velocity at the end of 5 seconds

Answers

Answer:

Step-by-step explanation:

If the velocity of a falling body varies directly as the time of flight, this is expressed as;

v α t

v = kt

k = v/t

If at t = 2secs, v = 64.4ft/s

k = 64/2

k = 32 ft

To get the velocity at the end of 5 secs, we will say;

at t = 5secs v = ?

From the formula;

v = kt

v = 32(5)

v = 160ft/s

Hence the required velocity is 160ft/s
