Answer:
45 and 135degrees
Step-by-step explanation:
Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this
In trigonometry, cosx = sin(90-x)
Hence:
Cos(8x+21) = sin(90-(8x+21))
Cos(8x+21) = sin(90-8x-21)
Cos(8x+21) = sin(-8x+69)
Substituting into the expression given, :
sin(-8x+69) = sin(-2x+51)
-8x+69 = -2x+51
-8x+2x = 51-69.
-6x = -18.
X = 18/6
X = 3
Since the angles 8x+21
Angle = 8(3)+21
Angle = 45
The angles represented in degrees are 45 and (180-45) = 135degrees
in the year 2001, a person bought a new car for $22000. for each consecutive year after that, the value of the car depreciated by 5%. how much would the car be worth in the year 2005, to the nearest hundred dollars
Answer:
To the nearest hundred dollars, the car will be worth $17,900 by 2005
Step-by-step explanation:
Firstly, we need to write the depreciation equation
We have this as:
V = I(1 - r)^t
V is the present value which is what we want to calculate
I is the initial value, the amount the cad was bought which is $22,000
r is the rate of change which is 5% = 5/100 = 0.05
t is the time difference which is 2005-2001 = 4
Substituting all these into the depreciation equation, we have it that
V = 22,000(1 -0.05)^4
V = $17,919.1375
To the nearest hundred dollars, that would be;
$17,900

Bill's flower garden has an area of 28 square feet. The rectangular garden is 7 feet long. What is the width of the garden?A. 4 feet
B. 8 feet
C. 21 feet
D. 35 feet
Answer:
A. 4 feet
Step-by-step explanation:
The area of something is found by multiplying the length by the width. So to find the answer, you divide 28 by 7 to get 4.

An observer standing on the southern bank of a river sees a tree that is much more than 100 feet downstream on the northern bank of the river. The angle formed by the southern bank and the line from the observer to the tree is 15 ∘. After walking 100 feet downstream, the observer measures the angle formed by the southern bank and the line to the same tree to be 25 ∘. Find the width of the river. (can you show the work please)(also the drawing please)
Answer:
[tex]63\ \text{ft}[/tex]
Step-by-step explanation:
The distances are shown in the figure
[tex]\tan25^{\circ}=\dfrac{p}{b}\\\Rightarrow p=b\tan25^{\circ}[/tex]
[tex]\tan15^{\circ}=\dfrac{p}{b+100}\\\Rightarrow p=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b\tan25^{\circ}=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b=\dfrac{100\tan15^{\circ}}{\tan25^{\circ}-\tan15^{\circ}}\\\Rightarrow b=135.08\ \text{ft}[/tex]
[tex]p=b\tan25^{\circ}=135.08\times\tan25^{\circ}\\\Rightarrow p=62.99\approx 63\ \text{ft}[/tex]
The width of the river is [tex]63\ \text{ft}[/tex].

49.5cm²
Step-by-step explanation:
(11x9)/2=99/2=49.5cm²
Help I need to find area and it’s due by 8
Answer:
20 1/2
Step-by-step explanation:
because area equals length times width
Answer and Step-by-step explanation:
First, let's split the figure into two common shapes that we know the area formula for.
The top shape can become a triangle, while the bottom shape can become a rectangle.
We know the area of a triangle is
[tex]A = \frac{bh}{2}[/tex]
and the area of a rectangle is
A = lw
Where:
A = Area
b = Base length (length)
h = Height
l = Longer length of a side
w = Smaller length of a side
Area of a Triangle:
b = 3
h = 3
A = [tex]\frac{3 * 3}{2}[/tex]
A = 4.5
Area of a Rectangle:
w = 3
l = 8
A = 3 × 8
A = 24
Now we add together the areas to get the area of the figure.
Area of the Figure:
A = 4.5 + 24
A = 28.5
The area of the figure is 28.5 [tex]units^{2}[/tex].

what is the average rate of change of h(x) over the interval -13
Can you slove this 6=2(y+2)
Answer:
y=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6=2(y+2)
6=(2)(y)+(2)(2)(Distribute)
6=2y+4
Step 2: Flip the equation.
2y+4=6
Step 3: Subtract 4 from both sides.
2y+4−4=6−4
2y=2
Step 4: Divide both sides by 2.
2y/2 2/2
Simplify the expression.

A 20ft ladder leans up against the wall. if the ladder is 3ft from the wall, what angle does the ladder make with the ground
Answer:
θ ≈ 81.37°Explanation:
let the angle the ladder makes with the ground be θ
θ = cos⁻¹(3/20)
θ = cos⁻¹(0.15)
θ ≈ 81.37°
