Answer:
Step-by-step explanation:
10) Cos (x-y) = cos x cos y + sin x sin y
cos 4x cox 3x + sin 4x sin 3x = Cos (4x - 3x)
= cos x
11) = 2*(1² + 2) + 2*(2² + 2²)
= 2*3 + 2*(4+4)
= 6 + 2*8
= 6 + 16
= 22
12) (3) 4x² - 3x - 8 = 0
Reason:
Sum of roots = - Coefficient of x/coefficient of x² = -(-3)/4 = 3/4
Product of roots = constant / coefficient of x² = -8/4 = -2
Draw the line and write an equation.
Line where the slope is 2, y-intercept is -1.
Complete the equation below
y=_______________
Use x as your variable.
Answer:
y = 2x - 1
Step-by-step explanation:
Slope intercept form is written as y = mx + b. Slope is m, so you substitute 2 for m. Y intercept is b, so you substitute -1 for b.

If the diameter of a men’s basketball is 10 inches and a women’s is 9 inches, what is the approximate difference of their volumes?
Answer:
141.89526818714 cubic inches
Step-by-step explanation \
Vm = Volume of the men's basketball
Vm = (4/3)*pi*r^3
Vm = (4/3)*pi*(5)^3 ... diameter = 10 --> radius = 10/2 = 5
Vm = 523.598775598299 cubic inches
Vw = Volume of the women's basketball
Vw = (4/3)*pi*r^3
Vw = (4/3)*pi*(4.5)^3 ... diameter = 9 --> radius = 9/2 = 4.5
Vw = 381.70350741116 cubic inches
Difference in volume = Vm - Vw
Difference in volume = 523.598775598299 - 381.70350741116
Difference in volume = 141.89526818714 cubic inches
This result is approximate

4. A rectangular park has been constructed in
downtown Lilburn. The designer wants to put a gravel
walkway that cuts diagonally through the park. The
width is 8 ft and the height is 6 ft long. What is the
length of his walkway?
Answer:
10ft
Step-by-step explanation:
Think of the rectangle as two right triangles. Sides a and b on the triangle are 8ft and 6 ft. That's 8 squared + 6 squared = c squared. C is 10 ft.
The requried measure of the length of the walkway is 10 feet.
As mentioned in the question, The designer wants to put a gravel walkway that cuts diagonally through the park. The width is 8 ft and the height is 6 ft long.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
here,
As of the given condition apply Pythagoras' theorem,
length² = width² + height²
length = √6²+8²
length = √100
length = 10 feet
Thus, the requried measure of the length of the walkway is 10 feet.

Jimmy is about to pick a marble from the jar. How likely is it that he will pick a blue marble?
Answer:
depends on how many different colors there are in the jar and how many marbles there are.
Step-by-step explanation:
There are 4 yellow marbles, 6 green marbles, and 5 blue marbles in a jar. Event A is defined as drawing a green marble from the jar on the first draw. Event B is defined as drawing a yellow marble on the second draw.
If two marbles are drawn from the bag, one after the other without replacement, what is P(B|A) expressed in simplest form?
A)4/15
B)2/7
C)1/3
D)2/5
Answer:(a)
Step-by-step explanation:
Given
There are 4 yellow, 6 green and 5 blue marbles
We have to find [tex]P(B\mid A)[/tex] i.e. conditional probability of B given that A is occurred.
[tex]P(B\mid A)[/tex] is given by
[tex]P(B\mid A)=\dfrac{P(A\cap B)}{P(A)}[/tex]
Also A=drawing a green marble
B=drawing a yellow marble
Total no of marbles [tex]=4+6+5=15[/tex]
So,
[tex]P(A)=\dfrac{6}{15}[/tex]
similarly [tex]P(B)=\dfrac{4}{15}[/tex]
[tex]P(A\cap B)=P(A)\times P(B)[/tex]
[tex]P(A\cap B)=\dfrac{6}{15}\times \dfrac{4}{15}[/tex]
[tex]P(A\cap B)=\frac{24}{225}[/tex]
Substituting the values in the formula
[tex]P(B\mid A)=\dfrac{\frac{24}{225}}{\frac{6}{15}}[/tex]
[tex]P(B\mid A)=\frac{24}{6}\times \frac{15}{225}[/tex]
[tex]P(B\mid A)=\frac{4}{15}[/tex]

Answer: y² - 5
Step-by-step explanation:
Five less than y squared...
First, let’s establish the y squared.
It should look something like this:
y²
But, we know that we need 5 less than y squared.
Therefore, we know there needs to be subtraction.
I think about it this way:
When you have y squared, you need 5 less than it, or y squared - 5.
Therefore, your answer is y² - 5.

Answer:
Hello There. I think the Correct answer is (4y+1)(y+6)
Step-by-step explanation:
Well I can't grid it for you, you didn't get give enough detail, however I can do the factoring.
Step-by-step explanation:
Given equation [tex]4y^{2} + 25y + 6[/tex][tex]4y^{2} + 25y + 6[/tex]
We have to write the given equation in factors form and then represent the factors on grid.
Consider the given equation [tex]4y^{2} + 24y + y + 6[/tex]
25y can be written as 24y + y , we get
⇒ [tex]4y^{2} + 24y + y + 6[/tex]
Taking 4y common from first two term and 1 common from last two term, we get,
⇒ [tex]4y(y + 6) + 1 (y + 6)[/tex]
⇒ [tex](4y + 1) (y + 6)[/tex]
Thus, factored form of given equation [tex]4y^{2} + 25y + 6 (4y + 1) (y + 6)[/tex]
Hope it helps!
From ItsNobody
The quadratic expression 4y^2 + 25y + 6 is factored by finding two numbers that multiply to 24 (product of A and C) and add up to 25 (the middle coefficient B). These numbers are 24 and 1, which leads to factoring the expression as (4y + 1)(y + 6).
Explanation:To factor the quadratic expression 4y^2 + 25y + 6, we will use the method of factoring by grouping or the AC method, where 'A' is the coefficient of the squared term and 'C' is the constant term.
Step 1: Multiply 'A' and 'C' (4 * 6 = 24) and find two numbers that multiply to 24 and add up to 'B' (the coefficient of the y term, which is 25).
Step 2: After finding the numbers 24 and 1 (since 24 * 1 = 24 and 24 + 1 = 25), rewrite the middle term (25y) as 24y + y.
Step 3: The expression now looks like 4y^2 + 24y + y + 6. Group the terms to factor by grouping: (4y^2 + 24y) and (y + 6).
Step 4: Factor out common terms from each group: 4y(y + 6) + 1(y + 6).
Step 5: Now that we have a common factor of (y + 6), the expression can be written as (4y + 1)(y + 6).
