Answer:

b

Step-by-step explanation:

Answer:

B.33

Step-by-step explanation:

Plug in 2 for x

(2)^3+6(2)^2+3(2)-5=

Answer:

B

Step-by-step explanation:

Remark

F(2) means that wherever you see an x on the right side of the equal sign, you substitute 2 for.

Suppose the question was f(2) = 3x + 5

Put a 2 where the x is.

f(2) = 3*2 + 5

f(2) = 6 + 5

f(2) = 11

Equation

f(x) = x3 + 6x2 + 3x -5.

Solution

f(2) = 2^3 + 6*2^2 + 3*2 - 5

f(2) =  8 + 6*4 + 6 - 5

f(2) = 8 + 24 + 1

f(2) = 33

Answer:

The base of the banner is 30 centimeters.

Step-by-step explanation:

Area = base × height

Plug in the numbers:

127 1/2 = b × 4 1/4

Convert mixed fractions into improper fractions for easier calculations.

Improper fraction formula: (denominator × mixed number + numerator)/denoninator

(2 × 127 + 1)/2 = 255/2

(4 × 4 + 1)/4 = 17/4

Rewrite equation:

255/2 = b × 17/4

Isolate variable b by multiplying the reciprocal of 17/4 (which is 4/17).

1020/34 = b

Simplify.

30 = b

Answer:

x = 7 hope this helps !!!

Step-by-step explanation:

Type 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. You can multiply the short side by the square root of 3 to find the long leg.

Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. Multiply this answer by the square root of 3 to find the long leg.

Type 3: You know the long leg (the side across from the 60-degree angle). Divide this side by the square root of 3 to find the short side. Double that figure to find the hypotenuse.

this is a type 3 triangle, and you can find the length of y from it, it being 14, and x is half of y, being 7

Tan (30) = x/7[tex]\sqrt{3}[/tex]

Tan (30) times [tex]7\sqrt{3}[/tex] = x

7 = x

Answer:

33250

Step-by-step explanation:

Find 1%

100% = 19000

1% = 19000 ÷ 100 = 190

100% + 75% = 175%

175% = 190 x 175 = 33250

Answer:

  >180° (more than 180°)

Step-by-step explanation:

Angles are classified as ...

It seems that we're looking at definitions:

  obtuse : >90° :: reflex : >180°

Answer:

The correct options are:

A, B, and E.

Step-by-step explanation:

A mathematical sentence (or a mathematical statement) is a sentence that can be true or false.

This is the only criteria we need to check, now let's analyze each option.

A: 4 - d = 12

This can be true or false, for example, if d = 0 the sentence is false because:

4 - 0 = 12

4 = 12 is false.

and if d = -8 the sentence is true, because:

4 - (-8) = 12

4 + 8 = 12

12 = 12

is true.

B: 4 - V > 2

This sentence can be true or false, same reasoning as before, we can find values of V such that this is true or false.

C: 3 + 2

Now, here we can't say if this is true or false, so this is not a mathematical sentence.

D: 59

Same as before, this is just a number.

E: 6 + a = 13

This can be true or false, depending on the value of a, then this is a mathematical sentence.

F: 12*x

Here we can not say if this is true or false, so this is not a mathematical sentence.

The correct options are:

A, B, and E.

Answer:

(n-2)²

Step-by-step explanation:

If triangle PQR is similar to triangle XYZ, then;

PQ/QR =XY/YZ

Given

PQ = n + 2,

QR = n - 2 and

XY=n^2 - 4,

Substitute

n+2/n-2 = n²-4/YZ

n+2/n-2 = (n+2)(n-2)/YZ

1/n-2 = n-2/YZ

Cross multiply

YZ = (n-2)(n-2)

YZ = (n-2)²

Hence the value of YZ in terms of n is (n-2)²

Step-by-step explanation:

we do this because when you start multiplying your 2nd digit you would put the zero to signifie that you started a mother digit.

if this is not what your looking for then sorry

Answer:

x = 20

Step-by-step explanation:

The angles are supplementary so:

7x + x + 20 = 180

8x + 20 = 180

8x = 160

x = 20

Answer:

$20,960

Step-by-step explanation:

Melissa's parent saved 8 000 dollars in the bank for her college fund account. It earns 9% annual interest. After 18 years, how much interest will it accumulate and how much is the total amount that Melissa will have fore her college fund.=> 9% = 9% / 100% = 0.09Let's find the annuak interest first => 8 000 dollars * .09 = 720 dollars The, let's find the after 18 years interest=> 720 dollars * 18 = 12 960 dollarsTotal of the amount: => 8 000 + 12 960 = 20 960 dollars

This is the same as the one above me but in simpler terms

Step-by-step explanation:

I =8000 x 9 x 18 =12,960

Total amount = 12960 +8000= $20,960

Answer:

$12960

Step-by-step explanation:

A=P(1+rt)

8000(1 + (0.09 × 18)) = 20960

A = $20,960.

I = A - P

I=20960-8000

ANS=$12960

Answer:

4x²√4√6√x⁶√x

Step-by-step explanation:

4x²√(24x⁷)

The above expression can be simplified as follow:

4x²√(24x⁷)

Recall

√(MN) = √M × √N = √M√N

Thus,

4x²√(24x⁷) = 4x²√24√x⁷

But:

√24 = √(4×6) = √4√6

√x⁷ = √x⁶√x

Thus,

4x²√24√x⁷ = 4x²√4√6√x⁶√x

Therefore,

4x²√(24x⁷) = 4x²√4√6√x⁶√x

Answer:

6 yards is more, 6 yards converted into inches is 216

Step-by-step explanation:

Answer:

6 yards

Step-by-step explanation:

1 inch = 0.0277778 yard

=> 215 inches = 5.97222 yards

- But 5.97222 < 6

Therefore, 6 yards are longer than 215 inches
