Applying the sine ratio and the Pythagorean theorem, the adjecent length to angle β is: A. 16.7 cm.
What is the Sine Ratio?The sine ratio is given as, sin ∅ = opposite/hypotenuse.
Given the following in a right triangle:
∅ = β sin(β) = 0.292Hypotenuse = 17.5 cmFind the opposite side by applying the sine ratio:
0.292 = opp/17.5
Opposite = (0.292)(17.5)
Opposite = 5.11
Using the Pythagorean theorem, we have:
Adjacent length = √(17.5² - 5.11²)
Adjacent length = 16.7 cm.
Thus, applying the sine ratio and the Pythagorean theorem, the adjecent length to angle β is: A. 16.7 cm.

if it rains on one day, the probability
that it will rain on the next day is 0.8
if it does not rain on one day, the probability that it will rain on the next day is 0.6
A weather forecaster says,
“There is a 70% chance that it will rain in the village on Monday.”
Work out an estimate for the probability that it will rain in the village on Wednesday.
lou must show all your working.
Using it's concept, it is found that there is a 0.643 = 64.3% probability that it will rain in the village on Wednesday.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, considering Monday - Tuesday - Wednesday, the possible outcomes are as follows:
R - R - R(0.7 x 0.7 x 0.7)
R - N - R(0.7 x 0.2 x 0.6)
N - R - R(0.3 x 0.6 x 0.8)
N - N - R(0.3 x 0.4 x 0.6)
Then, the probability is given by:
p = 0.7 x 0.7 x 0.7 + 0.7 x 0.2 x 0.6 + 0.3 x 0.6 x 0.8 + 0.3 x 0.4 x 0.6 = 0.643.

x2 + 8x + 19 = 0 What is the equivilent that results from completing the square?
Answer:
[tex](x+4)^2+3=0[/tex]
Step-by-step explanation:
Hey there!
Standard form is what this equation is in
Standard form is this: [tex]ax^2+bx+c[/tex]
So order to complete the square, you need to take the [tex]b[/tex] term out of the equation, divide it by two, and then square it
In this case, the [tex]b[/tex] term is 8
We need to divide 8 by 2 ---> 4
Then square 4 ---> 16
So now you should add 16 to both sides
[tex]x^2+8x+16+19=16[/tex]
Now you can simplify the LHS
[tex](x+4)^2 +19=16[/tex]
Now you subtract 16 from both sides
[tex](x+4)^2+3=0[/tex]
So this is as far as you can go since you cannot take the square root of a negative number

Answer:
Area of composite shape = 36 square units
Step-by-step explanation:
Area of composite shape:
Rectangle I:
Length = 3 units
width = 6 - 4 = 2 units
Area of rectangle I = length *width
= 3* 2
= 6 square units
Rectangle II:
length = 6 units
width = 5 units
Area of rectangle II = 6 * 5
= 30 square units
Area of composite shape = area of rectangle I + area of rectangle II
= 6 + 30
= 36 square units
Which equation is represented by the graph below?
i’ll make brainlyesttttt
Answer:
y=e^x - 4
Step-by-step explanation:
The log functions decrease with increasing x. The line shown increases as x increases, so it must be one of the two e^x equations. We can decide which one by calculating which equation povides the correct values to match the two points the curve crosses the y and x axes.
The graph shows the line crossing the y axis at -3 (0,-3)
It shows it crossing the x axis at a little over 1, perhaps 1.4 (1.4,0).
When x=0, e^0 = 1.
Look at the point (0,-3):
We know the e term will be 1 (e^0 = 1), so for y to be -3, we need to subtract 4: The form e^x - 4 would yield a value for y, when x is 0, of y = 1 - 4 or -3.
Check the other point (1.4,0):
y = e^1.4 is equal to 4.00
y = 4.00 - 4
y = 0
This point is also correct (1.4,0)
The correct equation is y=e^x - 4
Trevor is analyzing a circle, y2 + x2 = 100, and a linear function g(x). Will they intersect? y2 + x2 = 100 g(x) graph of the function y squared plus x squared equals 100 x g(x) −1 −22 0 −20 1 −18
Yes, at positive x coordinates
Yes, at negative x coordinates
Yes, at negative and positive x coordinates
No, they will not intersect
Answer:
Yes, at positive x coordinates
Step-by-step explanation:
Find the equation of g(x)
Given ordered pairs of g(x): (-1, -22) (0, -20) (1, -18)
[tex]\sf let\:(x_1,y_1)=(0,-20)[/tex]
[tex]\sf let\:(x_2,y_2)=(1,-18)[/tex]
[tex]\sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-18-(-20)}{1-0}=2[/tex]
Point-slope form of linear function: [tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-(-20)=2(x-0)[/tex]
[tex]\implies \sf y=2x-20[/tex]
Substitute the equation of g(x) into the equation of the circle and solve for x
Given equation: [tex]y^2+x^2=100[/tex]
[tex]\implies (2x-20)^2+x^2=100[/tex]
[tex]\implies 4x^2-80x+400+x^2=100[/tex]
[tex]\implies 5x^2-80x+300=0[/tex]
[tex]\implies x^2-16x+60=0[/tex]
[tex]\implies x^2-10x-6x+60=0[/tex]
[tex]\implies x(x-10)-6(x-10)=0[/tex]
[tex]\implies (x-6)(x-10)=0[/tex]
Therefore:
[tex](x-6)=0 \implies x=6[/tex]
[tex](x-10)=0 \implies x=10[/tex]
So the linear function g(x) will intersect the equation of the circle at positive x coordinates.
A cylinder has a height that is twice the length of the diameter. The diameter of the cylinder is 10 centimeters. What is the surface area of the cylinder?
Type the correct answer in the box. Use numerals instead of words.
The surface area is square centimeters.
Answer:
Step-by-step explanation:
Givens
pi = 3.14
d = 10 cm
h = 2*d
Formula
The top of the cylinder is a solid circle. So the area of the circle is pi r^2There is both a top and bottom to the circle so the fomula is 2*pi*r^2The surrounding area of the cylinder is the circumference of the circle times the height. The circumference of the circle is 2*pi*r. Then you just multiply by the height.formula = 2*pi * r * hThe combined formula is given below.
SA = 2*pi*r^2 + 2*pi*r * h
Conversions
d = 10 cm
h = 2*10
h = 20 cm
r = d/2
r = 10 / 2
r = 5cm
Solution
SA = 2*pi*r^2 + 2*pi*r * h
SA = 2*3.14*5^2 + 2*3.14*5*20
SA = 157 + 628
SA = 785 cm^2

Answer:
21.5 square units
Step-by-step explanation:
The 4 circles touching eachother have a total combined length of 20.
There are 4 circles. 20/4 = 5. The diameter of each circle is 5 units.
The length ofthe rectangle is 20 units. the width of the rectangle is 5 units.
The area of the shaded region is the area of the rectangle minus the ares of 4 circles.
A = area of rectangle - area of 4 circles
A = LW - 4 × πr²
The radius of each ciorcle is d/2 = 5/2 = 2.5
A = 20 × 5 - 4 × 3.14 × 2.5²
A = 100 - 78.5
A = 21.5
What steps are used to solve the equation 146 + f = 225
Answer:
f = 79
Step-by-step explanation:
You need to perform one-step equations process
146 + f = 225 (You're trying to solve for "f")
*First way, you could subtract both sides by 146 which makes the 146 cancel out then do 225-146 = 79. So f is 79
*A rule to remember is that the opposite of addition is subtraction. If you move 146 to 225 side you must switch it to negative 146.

what is the value of X in the following diagram?
Answer:
x = 98 degrees
Step-by-step explanation:
The sum of angles in a pentagon is 540 degrees. You can find this with the formula where n is the number of sides: 180(n-2). This formula will find the angle sum of a polygon. Now, since you know the value of every other angle except X, we can construct the equation 112+100+113+117+x=540
Solving this equation yields x=98 degrees
Sum of angles in a pentagon is 540°
x = 540 - (117+113+100+112)
x = 540 - 442
x = 98°
