Answer 1
Answer:

a) 640.32 cm^3

b) 98.4 cm^3

Step-by-step explanation:Part a)Cylinder volume:

(3.14) × 2^2 × 12 = 150.72 cm^3

Triangular prism:

We need to find the height of the base so we use the Pythagorean theorem.

5^2 + x^2 = 14.1^2

25 + x^2 = 198.81

x^2 = 173.81

x = 13.184

After finding height, we can use the equation for a normal triangular prism:

[tex]\frac{1}{2}[/tex] × Base × Height × Length

[tex]\frac{1}{2}[/tex] × 13.184 × 10 × 12= 791.04cm^3

Total Volume: 791.04 - 150.72 = 640.32 cm^3

Part b)Small Sphere Volume:

[tex]\frac{4}3[/tex] × 3.14 × 1^3 = [tex]\frac{314}{75}[/tex]cm^3

Half Sphere Volume :

0.5([tex]\frac{4}3[/tex]× 3.14 × 3^3) = 56.52cm^3

Cone Height:

5^2 = 3^2 + h^2

25 = 9 + h^2

16 = h^2

h = 4

Cone Volume:

(3.14) × 3^2 × [tex]\frac{4}{3}[/tex] = 37.68 cm^3

Total Volume = 98.4 after rounding

Write in factored form: ( )2

4( Choose ONE of the following polynomial and factor completely, showing ALL work.
16x2 − 81
15x2 − 35
3x2 + 21x + 36

Answers

Answer:

x+3 and x+2( 5 x + 2 ) ( x 2 + 5 )9x^2+163x2 + 21x + 36

Step-by-step explanation:

x2 + 5x + 6

Let us try factorizing this polynomial using splitting the middle term method.

Factoring polynomials by splitting the middle term:

We need to find two numbers ‘a’ and ‘b’ such that a + b =5 and ab = 6.

On solving this we obtain, a = 3 and b = 2

Thus, the above expression can be written as:

x2 + 5x + 6

= x2 + 3x + 2x + 6

= x(x + 3) + 2(x + 3)

= (x + 3)(x + 2)

Thus, x+3 and x+2 are the factors of the polynomial x2 + 5x + 6.

For Step 1, you just want to find all combinations of two numbers that multiply together to be 56. Make sure you take negatives into account. Those pairs of numbers are:

 

(p, q, p+q)

(1, 56, 57)

(-1, -56, -57)

(2, 28, 30)

(-2, -28, -30)

(4, 14, 18)

(-4, -14, -18)

(7, 8, 15)

(-7, -8, -15)

 

Use those pairs of numbers and their sums to fill in the three columns of your table.

STEP 2   Look down your p+q column to find the pair of numbers that add up to equal to -15. That's (p, q) = (-7, -8).   STEP 3   Using the information from steps 1 and 2, you can factor the trinomial like this:   x2 - 15x + 56 = (x + p)(x + q) = (x - 7)(x - 8)   FOIL that back out if you'd like, to make sure the expressions are equivalent.  STEP 4   Hopefully, seeing steps 1 through 3 worked out will help you with step 4. Find all the pairs of numbers that multiply together to be 36 (1 and 36, 2 and 18, 3 and 12, 4 and 9, 6 and 6, and all their negative equivalents), then figure out which pair has a sum of 12. That means you've found your p and q, and can factor the trinomial as (x + p)(x + q).

Answer:

1) Factor the trinomial. Show ALL work:

(x-2)(x-3) steps see explanation

2) Factor the polynomial using grouping.

Group and factor out the greatest common factor (GCF), then combine.

[tex](5x-2) (x^{2} +5)[/tex]

4) Choose ONE of the following polynomial and factor completely.

15x2 − 35 = [tex]5 (3x^2-7)[/tex]

Step-by-step explanation:

x2−5x+6

The middle number is -5 and the last number is 6.

Factoring means we want something like

(x+_)(x+_)

We need two numbers that

Add together to get -5

Multiply together to get 6

Try -2 and -3:

-2+-3 = -5

-2*-3 = 6

Based on these results, express the probability that the next person will purchase
exactly one costume as a decimal to the nearest hundredth.
Mk

Answers

Answer: 0.59

Step-by-step explanation:

The probability that the next person will purchase exactly one costume is 0.59.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total number of visitors = 126+228+34 = 388

Total number of visitors who purchased exactly one costume = 228

The probability = 228/388 = 0.587 ≈ 0.59

Thus, the probability that the next person will purchase exactly one costume is 0.59.

Answer:

  (c)  9

Step-by-step explanation:

The square of a binomial has the form ...

  (x +a)² = x² +(2a)x +a²

You will note that the value of 'a' is half the coefficient of the x term (2a). The constant term is the square of the value of 'a'. This means the number you want is ...

  c = (6/2)² = 9

Answer:

9

Step-by-step explanation:

Rearrange the equation so uuu is the independent variable.
-12u+13=8w-3

Answers

Answer:

u = 8w-16 /-12        or  =  - 8w-16/12 both mean the same due to the a/-b- = -a/b rule. Then you can factor out the rest. note the fnew subtraction changes mean the same as - (a/b) and should show without brackets as a centre pointing whole fraction subtraction sign.

Step-by-step explanation:

-12u -13 = 8w-3

-12u+13 -13 = 8w-3-13     Eliminate -13 by +13 both sides

-12u = 8w-16                      So you are left with one value left side.

-12u/-12  =  8/-12 - 16/-12   Then divide all values by -12 to find value for u and keep the subtraction as 8 never had subtraction sign and no multiplication .

u = 8w-16 /-12                   Then you can factor out the rest

This has made u the independent variable then you have a choice to continue showing or ignore u; as u =

=       -  8(w-2)/12       Step 1   Factor with subtraction change from -12  to - central fraction

=         - 2(w-2)/3      Step 2   Simplify with new minus sign for central fraction to replace a/-b

Step-by-step explanation:

Which statement is accurate for the right triangle shown below?

50
1
a
47

Answers

Answer:

The statement that is accurate is csc(θ)=1.06

Step-by-step explanation:

Looking at the reference angle in this triangle, we can see that the side that is 47 units is opposite of it, the side that is 50 units is the hypotenuse, and the side that is 17 units is adjacent to it.

Because we know this, we can plug our sides into the formula for cscθ, secθ, and cotθ.

So:

cotθ=adjacent/opposite = 17/47= 0.36

cscθ=hypotenuse/opposite = 50/47=1.06

Now without even looking at the other statements, we can see that the second one is correct as cscθ=hypotenuse/opposite = 50/47=1.06

Therefore, the statement that is accurate is csc(θ)=1.06.

Please solve the question with steps.
