Answer:
∠ A ≈ 75.7°
Step-by-step explanation:
Given
[tex]\frac{sinA}{8}[/tex] = [tex]\frac{sin58}{7}[/tex] ( cross- multiply )
7 × sinA = 8 × sin58° ( divide both sides by 7 )
sinA = [tex]\frac{8sin58}{7}[/tex] , then
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{8sin58}{7}[/tex] ) ≈ 75.7° ( to the nearest tenth )

A ship is sighted from the top of a lighthouse. The angle of depression from the lighthouse to the ship is 45degrees. The distance from the top of the lighthouse directly to the ship is 4miles.Calculate the horizontal distance of the ship from the bottom of the lighthouse
Answers
Answer:
[tex]2\sqrt{2} \text{ mi}[/tex]
Step-by-step explanation:
See the attached image for a picture of the situation. The angle of depression lets you find the angle next to it but inside the triangle. It, too, must measure 45 degrees.
That means the triangle is an isosceles triangle (two legs of equal length).
Apply the Pythagorean Theorem.
[tex]x^2+x^2=4^2\\2x^2=16\\x^2=18\\x=\sqrt{8}=2\sqrt{2}\approx 2.83\text{ mi}[/tex]

A cylinder has a diameter of 10cm. The height of the cylinder is 2 5 the length of the diameter. Calculate the volume of the cylinder in terms of π.
Answers
Answer:
625 π cm^3
Step-by-step explanation:
volume of a cylinder = πr^2h
π = 22/7
r = radius = 10/2 = 5cm
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
π x (5^2) x 25 = 625 π

62n−1=36 help quick thank you soosoo much!!
Answers
Answer:
n = 37/62
Step-by-step explanation:
62n - 1 = 36
(Add 1 on both sides)
62n - 1 + 1 = 36 + 1
62n = 37
(Divide 62 on both sides)
62/62n = 37/62
n = 37/62
Answer:
n equals 0.596!
Step-by-step explanation:
62n − 1 = 36
62n = 36 + 1
62n = 37
n = [tex]\frac{37}{62}[/tex]
n = 0.596 (the number is huge but it can be written in short like this)
Which line has a slope of -2 and y-intercept of 3
Answers
Answer:
A
Step-by-step explanation:
The line has to go down when x move to the right due to the negative slope. So B and C cannot be right.
The line has to pass through (0,3), that's the y-intercept, so A and D can still both be right.
For every step to the right, the line has to move 2 down (slope -2). Only A does that. D moves 0.5 down for every step to the right.
Match each verbal description to its equivalent function rule as applied to the given function below. 3a – 7 = 6 - 9 = -3.1 14 (1) و = 3x - 7 = 121 – 19 = 60 - 2 = -31 28 The function fstretched vertically by a factor of 4 and translated up by 9 units The function ftranslated 6 units up and 2 units right The function freflected about the y-axis and translated 7 units left The function f stretched vertically by a factor of 2 and translated up by 5 units
Answers
Answer:f(x) = 3x - 7
6 up; 2 right = 3(x-2) - 7 + 6
= 3x - 6 - 7 + 6
= 3x - 7
reflected about y-axis; 7 left = -3(x+7) -7
= -3x - 21 - 7
= -3x - 28
up 5 ; 2 vert stretch = (2)(3x - 7) + 5
= 6x - 14 + 5
= 6x - 9
up 9 ; 4 vert stretch = (4)(3x - 7) + 9
= 12x - 28 + 9
= 12x - 19
Step-by-step explanation:
The transformation of a function may involve any change. The function f(x) stretched vertically by a factor of 2 and translated up by 5 units is (6x - 9).
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift:
Up by d units: y = f(x) + dDown by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: y = k × f(x)Horizontal stretch by a factor k: y = f(x/k)Given the function f(x)=3x-7, which can be transformed as shown below.
1. The function f(x) stretched vertically by a factor of 4 and translated up by 9 units.
Vertical stretch → 4(3x - 7) = 12x - 28
Up by 9 Units → (12x - 28) + 9
g(x) = 12x - 19
2. The function f(x) translated 6 units up and 2 units right
Up by 6 units → (3x - 7) +6 = 3x - 1
2 units Right → 3(x-2) - 1 = 3x - 6 - 1 = 3x - 7
g(x) = 3x - 7
3. The function f(x) reflected about the y-axis and translated 7 units left
Reflected about the y-axis → -3x - 7
7 units left → -3(x+7) - 7 = -3x - 21 -7 = -3x-28
g(x) = -3x-28
4. The function f(x) stretched vertically by a factor of 2 and translated up by 5 units
Stretched vertically by a factor of 2 → 2(3x - 7) = 6x - 14
Translated up by 5 units → 6x - 14 + 5 = 6x - 9
g(x) = 6x - 9

Write an equation in slope intercept form of the line with the given characteristics. = through: (-3,1), slope · 2
Answers
Answer:
y=2x+7
Step-by-step explanation:
Hi there!
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
we are given the slope (2), and a point (-3,1)
we can subsitute 2 as m into the equation
y=2x+b
we need to find b
Since the equation will pass through the point (-3,1), you can use it to solve for b.
substitute -3 as x and 1 as y
1=2(-3)+b
multiply
1=-6+b
7=b
therefore the equation of the line is y=2x+7

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has length 1/4 in. and width 1/6 in. The actual tiles have length 1/6 ft and width 1/9 ft.
What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile
Answers
Answer:
The answer is below
Step-by-step explanation:
The model is a tile with length 1/4 in. and width 1/6 in while the actual tile has length 1/6 ft. and width 1/9 ft.
Firstly we have to convert the model length and width from inches to feet.
1 feet = 12 inches
model length = 1/4 in. = 1/4 in * (1/12) ft./in = 1/48 ft.
model width = 1/6 in. = 1/6 in * (1/12) ft./in = 1/72 ft.
Therefore:
Ratio of model length to actual length of tile = (1/48 ft.) / (1/6 ft.) = 1 / 8
Ratio of model length to actual length of tile = (1/72 ft.) / (1/9 ft.) = 1 / 8
Area of model tile = length * width = 1/48 ft. * 1/72 ft. = 1/3456 ft²
Area of actual tile = length * width = 1/6 ft. * 1/9 ft. = 1/54 ft²
Ratio of model area to actual area of tile = (1/3456 ft²) / (1/54 ft²) = 1 / 64
In the diagram, three currents x, y and z are flowing in a circuit. The current y is 1 amp less than twice the current x. The current z is 2 ampere more than the current y. The total current x, y and z is 15 amperes. How many amperes is current x?
Answers
Answer:
3 A
Step-by-step explanation:
Current X = x
current Y = 2x -1
current Z = y + 2 = 2x - 1 + 2 = 2x + 1
Here, x + y + z = 15
x + 2 x - 1 + 2 x + 1 = 15
5 x = 15
x = 3 A
So, the current in x is 3 A.
