find the value of x and y in the triangles below
Answer:
x=9 y=24
Step-by-step explanation:
take the triangle with 43 Degrees and 90 degrees to get the answer for that missing angle.
which equals 133
subtract 133 from 180 and get 47
then set 5x+2 = 47 because opposite angles are equal to each other
-2 on both sides
5x=45
divide by 5
x=9
then take 3y+1=?
add 47 + 60 =107
180-107=73
3y+1=73
-1 both sides
72
divide by 3
y=24
to rent office space for your business, you must pay a one time fee of $1000 and pay rent of $800 per month.
A. Write a linear model that represents the total cost of renting office space as a function of number of monthd you will rent.
B. Find the total cost of renting office space for 6 months.
Answer:
Step-by-step explanation:
a) y=800x+1000=800(12)+1000
b)y=1000x (15 months)
Answer:
Linear model is given as
Total cost of renting = 1000 + n(800)
Total cost of renting for 6 months = $5800
Step-by-step explanation:
The linear model can be represented as follows ;
The one time fee = $1000
monthly fee = $ 800
Total cost of renting = 1000 + n(800)
n = number of month you will rent
Total cost of renting office space for 6 months can be computed using the model.
Total cost of renting = 1000 + n(800)
where n = 6 months
Total cost of renting for 6 months = 1000 + 6(800)
Total cost of renting for 6 months = 1000 + 4800
Total cost of renting for 6 months = $5800
rearranging familiar formulas the area A of rectangle is 25 in in formula for area is A=lw if the width w is 10 inches what is the lengh l
Answer:
2.5 in
Step-by-step explanation:
A = lw Divide each side by w
l = A/w
A = 25 in²; w = 10 in
l = 25/10
l= 2.5 in
If C is the hypotenuse of the right triangle ABC with sides A, B, C, and A=12, B=5, then C= ?
Answer:
13
Step-by-step explanation:
To solve for any missing side of a triangle, simply use the Pythagorean Theorem.
[tex]a^2 + b^2 = c^2[/tex]
[tex]c^2=12^2+5^2\\c^2 = 144 +25\\\sqrt{c^2} = \sqrt{169} \\\text{The square root of 169 is 13}[/tex]
The length of the hypotenuse (C) in a right triangle given sides A=12 and B=5 can be calculated using the Pythagorean theorem. Substituting these values leads to a calculation of √169, resulting in C being 13.
Explanation:The subject at hand pertains to the Pythagorean Theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (side C) is equal to the sum of the squares of the lengths of the other two sides (A and B). Hence, the formula is a² + b² = c².
Given that A=12 and B=5, we substitute these values into the Pythagorean theorem. Therefore, the calculation is C = √(12² + 5²). This simplifies to C = √(144 + 25), which further simplifies to C = √169. Thus, the length of the hypotenuse C is 13.

find the measure of angle B, note that angle B is acute
Answer:
B= 44.9506°
Step-by-step explanation:
WE apply sine angle formula
[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
Given angle C = 51, c= 11 and b = 10
[tex]\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
Plug in the values
[tex]\frac{10}{sin(B)}=\frac{11}{sin(51)}[/tex]
Cross multiply it
10 * sin(51) = 11* sin(B)
7.771459615 = 11 sin(B)
Now divide by 11 on both sides
0.706496328 = sin(B)
Now [tex]B = sin^{-1} (0.706496328)[/tex]
B= 44.9506°

As a financial consultant, the CFO of a major television company has shared the profit function P(x) = −x4 - 2x3 + 21x2 + 22x − 40 with you which models the profit of the company based on the number of commercials , x, they air in a 24-hour period. DESCRIBE the appearance of the graph to the CFO. Use complete sentences, and focus on the end behaviors of the graph and how to use the function P(x) to find where the company will break even (where P(x) = 0).
Answer:
The company will break even at x=1 and x=4.
Step-by-step explanation:
The given profit function is
[tex]P(x)=-x^4-2x^3+21x^2+22x-40[/tex]
Where, x is number of commercials.
Use synthetic division or long division to find the factors of the function.
[tex]P(x)=(x-1)(x^3+3x^2-18x-40)[/tex]
[tex]P(x)=(x-1)(x+2)(x^2+x-20)[/tex]
[tex]P(x) = -(x - 4) (x - 1) (x + 2) (x + 5)[/tex]
Equate P(x)=0, to find the break even points.
[tex]-(x - 4) (x - 1) (x + 2) (x + 5)=0[/tex]
Use zero product property and equate each factor equal to zero.
[tex]x=4,1,-2,-5[/tex]
Therefore the zeros of the function P(x) are 4, 1, -2 and -5. Since x is number of commercials, therefore the value of x must be positive. Therefore the company will break even at x=1 and x=4.
The higher degree of the function is even and the leading coefficient is negative. So,
[tex]P(x)\rightarrow -\infty \text{ as }x\rightarrow \infty[/tex]
[tex]P(x)\rightarrow -\infty \text{ as }x\rightarrow -\infty[/tex]
Since the value of x must be positive, therefore the left end point is y-intercept of the graph, i.e., (0,-40).
Therefore the company faces huge loss when the number of commercials increases unboundly.
The graph of the function is given below.
Point( -2 -1) and is perpendicular to the graph of y equals negative 2/3 x + 6. line n is parallel to line M and passes through point (4,-3). which is the equation of line and in slope intercept form

write this polynomial in descending form 5x3 + 2x + 7x5
The polynomial 5x3 + 2x + 7x5 written in descending form is 7x5 + 5x3 + 2x, organized from the highest to the lowest power of x.
To write the polynomial 5x3 + 2x + 7x5 in descending form, arrange the terms in order from the highest power of x to the lowest. The given polynomial has the terms with powers of 5, 3, and 1. Organizing the polynomial in descending order of the exponents gives us:
7x5 + 5x3 + 2x.
As we can see, the term with the highest exponent, 7x5 (degree 5), comes first, followed by 5x3 (degree 3), and lastly the term with the lowest degree, 2x (degree 1).

Answer:
c) 2.082
Step-by-step explanation:
First you would add 1.567 and 2.345 together to get 3.912. If you take 3.912 and subtract 1.83 from that, it would be 2.082.
Hey there!
1.567 + 2.345 - 1.83 (5)
1.567 + 2.345 = 3.912
3.912 - 1.83(5)
1.83(5) = 9.15
3.912 - 9.15 = -5.238
Answer: -5.238 ✅

What’s the question mark
Answer:
? = 30
Step-by-step explanation:
If the triangles are similar, then the only way I see this working is the sides measuring 63 and 54 are corresponding. The sides measuring 56 and 48 are corresponding. That leaves the sides measuring 35 and ? corresponding.
Set up a proportion.
63/54 = 35/?
63? = 54 * 35
63? = 1890
? = 30

4⋅(a⋅2) This is the same by the associative property of multiplication
2⋅(4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication
4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.
8a 4*2 = 8 so this is the same
4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
