Answer:

B

Step-by-step explanation:

The diagonal will become the hypotenuse of a right triangle, with the legs being 24 and 7.

Since it is a right triangle, we can use Pythagorean theorem

a^2+b^2=c^2

We know the legs: a and b, are 24 and 7, so we can substitute them in

24^2+7^2=c^2

Solve the exponents

576+49=c^2

Add

625=c^2

Take the square root of both sides

[tex]\sqrt{625}[/tex]=[tex]\sqrt{c^{2} }[/tex]

c=25

So, the diagonal will be 25 cm, or choice B

Answer:

25cm or b

Step-by-step explanation:

Answer:

Step-by-step explanation:

a triangle = 180

Q = 180 - (90 + 45)

Q = 180 - 135

Q = 45

Step-by-step explanation:

With reference angle 60°

perpendicular (p) = 2√3

hypotenuse (h) = ?

We know

sin 60° = p/h

√3/2 = 2√3 / h

cross multiply

h =( 2√3 * 2)/ √3

therefore h = 4

So

Now

with reference angle 45°

perpendicular (p) = x

base (b) = 4

Now

tan 45° = p/b

1 = x / 4

Therefore x = 4

Step-by-step explanation:

The area covered by security camera is 5642.18 square feet.

The region inside the portion of the circle formed by two radii and an arc is known as the area of a sector. It only covers a small portion of the entire circle's surface.

Area of sector = [tex]\theta[/tex] / 360 πR²

Given:

R= 150 /2 = 75 feet

Now, Area of sector = [tex]\theta[/tex] / 360 πR²

                                  = 115 / 360 x 3.14 x 75 x 75

                                  = 135412.5/24

                                  = 5642.18 square feet

Hence, the area covered by security camera is 5642.18 square feet.

3/(x-1) - 1/(x^2-1) = 5/(x-1)

Subtract 3/(x-1) from both sides

-1/(x^2-1) = 2/(x-1)

Factor x^2 - 1

-1/[(x-1)(x+1] = 2/(x-1)

Multiply by (x-1)(x+1) on both sides

-1 = 2 (x+1)

-1 = 2x + 2

Subtract 2 from both sides

-3 = 2x

Divide by 2 on both sides

-3/2 = x

Answer:

x = -3/2

Step-by-step explanation:

[tex]\frac{3(x+1)}{(x-1)(x+1)} - \frac{1}{(x-1)(x+1)} = \frac{5(x+1)}{(x-1)(x+1)} \\[/tex]  Find the common denominator

Answer:

The amount deducted for Ms.Everett‘s paycheck for her health insurance premium is $307.6

Step-by-step explanation:

given information:

annual insurance = $12304

employer pay annually = 70%

first we calculate the annual insurance paid by the employer

employer paid annual insurance = 70% x $12304

                                                      = $8612.8

then, we calculate the insurance paid by Ms. Everett annually

Ms. Everett paid annual insurance =  $12304 - $8612.8

                                                         = $3691.2

thus, amount is deducted for Ms.Everett‘s paycheck for her health insurance premium

Ms. Everett's paycheck deduct = $3691.2/12

                                                     = $307.6

To solve the quadratic equation x^2 + 9x + 18 = 0, you'll have to find values of x that satisfy this equation.

To find the roots of the quadratic equation, we use the formula x = [-b±sqrt(b^2 -4ac)]/2a, where a, b, c are the coefficients of the quadratic equation of the form: ax^2 + bx + c = 0.

In our equation, we have:
a = 1 (coefficient of x^2)
b = 9 (coefficient of x)
c = 18 (constant term)

Substituting these values in our formula, we get:

x = [-9±sqrt((9)^2 - 4*1*18)] / 2*1,
x = [-9±sqrt(81 - 72)] / 2,
x = [-9±sqrt(9)] / 2,
x = [-9±3] / 2.

From here, we get two solutions:

For the smaller solution, we have: x = [-9 - 3] / 2 = -6.

For the larger solution, we have: x = [-9 + 3] / 2 = -3.

So, the solutions to the equation x^2 + 9x + 18 = 0 are x = -6 (for the smaller solution), and x = -3 (for the larger solution).

Step-by-step explanation:

The mean of the data describes the data set , because it is the average of all the values of the set

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the data set be represented as A

Now , the value of A is noted

And , the median of the data set is the middle term of the set

where the mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values

So , the average values of the set determines the data values as it is a compilation of all the data values

Hence , the mean of the data describes the set

Step-by-step explanation:

To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula

(a)

8 - 1 = 7

8 - 2 = 6

8 - 3 = 5

The first 3 terms are 7, 6, 5

(b)

The first negative term wii occur when n > 8, that is n = 9, thus

8 - 9 = - 1 ← first negative term

The first three terms of the sequence defined by 8 - n are 7, 6, and 5. The first negative term is when n equals 9.

The nth term of a sequence is defined by 8 - n. This means that you subtract the term number (n) from 8 to get the value of the term.

Answer:

A

Step-by-step explanation:

Our given equation is: y = -2x - 8

In order to have an equation with infinitely many solutions, it needs to be the same as the given equation.

Look at the answer choices:

A) y = -(2x + 8) = -2x - 8

This is the exact same equation, which means that any solutions for the given will also be solutions for this one. That means there will be infinitely many solutions.

B) y = -2(x - 8) = -2x + 16

We can tell this is definitely not the same as the given, so eliminate.

C) y = -2(x - 4) = -2x + 8

Again, this has a +8 instead of -8, so it's not the same and wrong.

D) y = -(-2x + 8) = 2x - 8

Here, we have positive 2 as the slope instead of -2, so it's not the same and wrong.

Thus, the answer is A.

The answer is (D.) A credit union is a nonprofit entity; a commercial bank is a for-profit entity.

Step-by-step explanation:

While Credit unions are not-for-profit organizations that exist to serve their members Retail banks are for-profit organizations that exist to serve the general public. Just like retail banks, credit unions accept deposits, make loans and provide a wide array of other financial services, but mainly from registered members.. But as member-owned and cooperative institutions, credit unions provide a safe haven to members only to save and borrow at reasonable rates.

Answer:

A. A credit union is a non-depository institution; a retail bank takes customer deposits.
