Cos. 25 = y/44
Cos. 25 x 44 = y
0.9063 x 44 = y
39.8772 = y
Now that we have the altitude you can set up another equation for x.
Tan. 34 = x/39.8772
Tan. 34 x 39.8772 = x
0.6745 x 39.8772 = x
26.8971714 = x
Final Answer: x is approximately 26.9

3. In the rhombus, what are m∠1, m∠2 and m∠3? The diagram is not drawn to scale.
Answers
Answer: m∠1 = 128°, m∠2 = 26° and m∠3 = 26°.
Step-by-step explanation: We are given to find the measures of ∠1, ∠2 and ∠3 in the figure.
As shown in the attached figure, ABCD is a rhombus, where m∠A = 128°.
We know that, in a rhombus, all the sides are congruent, the opposite angles are congruent and the adjacent angles are supplementary.
So, from rhombus ABCD, we have
[tex]m\angle A=m\angle C~~~~~\textup{[opposite angles]}\\\\\Rightarrow m\angle 1=128^\circ.[/tex]
Also, in ΔBCD, we have
[tex]BC=CD~~\textup{[all the sides are congruent]}\\\\\Rightarrow m\angle 3=m\angle 2~~\textup{[angles opposite to congruent sides care congruent]}.[/tex]
Now, since the sum of three angles of a triangle is 180°, we have from ΔBCD that
[tex]m\angle 1+m\angle 2+m\angle 3=180^\circ\\\\\Rightarrow 128^\circ+m\angle 2+m\angle 2=180^\circ\\\\\Rightarrow 2\times m\angle 2=180^\circ-128^\circ\\\\\Rightarrow 2\times m\angle 2=52^\circ\\\\\Rightarrow m\angle 2=26^\circ.[/tex]
Therefore, m∠3 = 26°.
Thus, m∠1 = 128°, m∠2 = 26° and m∠3 = 26°.

The payment is 190,000*(.0725/12)/(1 -(1 +.0725/12)^(-12*20)) ≈ 1501.71
The total of all payments is 240*1501.71 = 360,410.40, so the interest cost is this amount less the principal, or $170410.40.
Total loan cost = $2800 + 1%*190,000 +170,410.40 = 175,110.40
Mortgage B:
The payment is 190,000*(.0525/12)/(1 -(1 +.0525/12)^-240) ≈ 1280.30
The total of all payments is 240*1280.30 = 307,272.00, so the total interest cost is $117,272.00.
Total loan cost = $2800 +5%*190,000 +117,272.00 = 129,572.00

Answers
27a^3+8c^3
Explanation.
In this question you are expected to expand (3a+2c)(9a^2-6ac+4c^2
(3a+2c)(9a^2-6ac+4c^2
=(3a×9a^2 )-(3a×6ac)+(3a×4c^2 )+(2c×9a^2 )-(2c×6ac)+(2c×4c^2 )
27a^3-18a^2 c+12ac^2+18a^2 c-12ac^2+8c^3
27a^3+8c^3
The expansion of the expression, (3a+2c)(9a^2-6ac+4c^2) is 27a^3+8. This is what the question requires.
Answer:
The product of [tex]\left(3a+2c\right)\left(9a^2-6ac+4c^2\right)=8c^3+27a^3[/tex]
Step-by-step explanation:
Given: Polynomial [tex]\left(3a+2c\right)\left(9a^2-6ac+4c^2\right)[/tex]
We have to place the indicated product in the proper location o the grid.
Consider the given product [tex]\left(3a+2c\right)\left(9a^2-6ac+4c^2\right)[/tex]
Using distributive property, Multiply each term of first bracket with each term of last bracket, we have,
[tex]=3a\cdot \:9a^2+3a\left(-6ac\right)+3a\cdot \:4c^2+2c\cdot \:9a^2+2c\left(-6ac\right)+2c\cdot \:4c^2[/tex]
Apply plus-minus rule [tex]+\left(-a\right)=-a[/tex] , we have,
[tex]=3\cdot \:9a^2a-3\cdot \:6aac+3\cdot \:4ac^2+2\cdot \:9a^2c-2\cdot \:6acc+2\cdot \:4c^2c[/tex]
Simplify, we have,
[tex]=27a^3-18a^2c+12ac^2+18a^2c-12ac^2+8c^3[/tex]
Adding similar terms, we have,
[tex]=8c^3+27a^3[/tex]
Thus, The product of [tex]\left(3a+2c\right)\left(9a^2-6ac+4c^2\right)=8c^3+27a^3[/tex]

Printer paper is sold in packages of 500 sheets. of a printing job uses 1 3/4 packages of paper how may sheets is that
Answers
[tex]1 \dfrac{3}{4} \text { package of papers = } 500 \times 1 \dfrac{3}{4} [/tex]
[tex]1 \dfrac{3}{4} \text { package of papers = } 500 \times \dfrac{7}{4} [/tex]
[tex]1 \dfrac{3}{4} \text { package of papers = } 875 \text { sheets}[/tex]
The printing job that uses 1 3/4 packages of printer paper requires 875 sheets.
To determine how many sheets of paper are used in a printing job that uses 1 3/4 packages of paper, follow these steps:
First, understand that 1 package contains 500 sheets of printer paper.Next, convert the mixed number 1 3/4 to an improper fraction. This is done by multiplying the whole number (1) by the denominator (4) and adding the numerator (3), giving us 7/4.Now, multiply the number of packages (7/4) by the number of sheets per package (500):7/4 * 500 sheets = (7 * 500) / 4 = 3500 / 4 = 875 sheets.
Therefore, the printing job uses 875 sheets of paper.

Given sinx=0.9 , what is cosx ? Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.
Answers
It is given sinx=0.9 .We need to find cosx.
We use the identity :
[tex] sin^{2} x + cos^{2} x =1 [/tex]
Substituting sinx=0.9
[tex] (0.9)^{2} +cos^{2} x =1 [/tex]
[tex] 0.81+cos^{2} x=1 [/tex]
Substracting 0.81 both sides:
[tex] cos^{2} x =1-0.81 [/tex]
[tex] cos^{2} x=0.19 [/tex]
Taking root of both sides cosx=0.435
Rounding to nearest hundredth
cosx=0.44.

Answers
As the x-values increase, the y-values decrease; this means it is a decreasing graph.
The graph shows a straight line with a constant rate of change, so it is linear.
Answer:
B. Linear decreasing
Step-by-step explanation:
We are given that,
The graph of the function is passing through the points (0,3) and (1.5,0).
Then, the rate of change is [tex]m=\frac{0-3}{1.5-0}=\frac{-3}{1.5}=-2[/tex]
So, the function is represented by a straight line with constant rate of change -2.
Thus, the function is a linear function.Moreover, as the value of x is increasing, we see that the value of y is decreasing.
So, the function is a decreasing function.Hence, option B is correct.

we know that at t = 0, the height of the rock is 16
choices H and I do not have a value of 16 at t = 0.
H: h(0) = -5.2(0)² + 24(0) - 12 = -12
I: h(0) = -4.2(0)² + 26(0) - 20 = -20
so we are left with F and G
if we take choice F and plug in t = 1
h(1) = -4.7(1)² - 25(1) + 16 = -13.7
if we take choice G and plug in t = 1
h(1) = -4.7(1)² + 25(1) + 16 = 36.3
only choice G works for us since it has 36.3 at t = 1

now, notice, is really just a large triangle in red, with a base of 4 and a height of 3 units, and two smaller triangles below it, one has a base 1 and a height of 1, and the other has a base of 3 and a height of 1.
so just get the area of each, sum them up, and that's the shaded area.
The total area of the figure is 8 square units.
How to find the area?
Remember that the area of a triangle is equal to its height times its base over 2.
In the image we can see 3 triangles, the larger one has a height of 3 units and a base of 4 units, so its area is:
A = 3*4/2 = 6 square units.
The bottom left triangle has a base of 1 unit and a height of 1 unit, so its area is:
A' = 1*1/2 = 0.5 square units.
The bottom right triangle has a base of 3 units, and a height of 1 unit, so its area is:
A'' = 1*3/2 = 1.5 square units.
The total area is:
A + A' + A'' = (6 + 0.5 + 1.5) square units = 8 square units.

sin^ 2 (theta) + cos^ 2 (theta) = 1
We substitute the values:
sin ^ 2 (theta) + 0.73 = 1

sin ^ 2 (theta) = 0.27
Answer:
a possible value of sin ^ 2 (theta) is:
c.0.26 (nearest option)
The correct answer is option a. 0.37.
Given that [tex]cos(2\theta) = 0.73[/tex], find a possible value of sin(theta).
It is known that:
[tex]cos(2\theta) = 1-2sin^2(\theta)[/tex].
Substituting the given value:
[tex]0.73 = 1-2sin^2(\theta)[/tex]
Rearrange to solve for sin²(theta):
[tex]2sin^2(\theta)=1-0.73[/tex]
[tex]2sin^2(\theta)=0.27[/tex]
[tex]sin^2(\theta)=0.135[/tex]
So, [tex]sin(\theta) = \sqrt{0.135}\ or\ sin(\theta) = -\sqrt{0.135}[/tex].
Since we are looking for a possible value, we take the positive root:
[tex]sin(\theta) \approx 0.367[/tex]
Considering the options given, the closest possible value is 0.37.
