Answer:
About 2.6 feet
Step-by-step explanation:
The tangent of an angle in a right triangle is the length of the opposite side divided by the length of the adjacent side. Therefore:
\(\tan 17= \dfrac{x}{8.6} \\\\x=\tan 17 \cdot 8.6\approx 2.6\)
Hope this helps!
Question 13 of 15
A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.
ANSWER : A AND D.
Step-by-step explanation:
the water current would be 2 mph and the canoe is 4 mph
See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.
The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.
The answers should be A and D.

Need answer in a few mins pls help f(x)=2 function: f(x)=3-√x x=?
Answer:
1=x
Step-by-step explanation:
The equation would be 2=3-√x *x
subtract 3 from both sides
-1=-√x *x
multiply x*x
-1=-√x^2
the square and the square root cancel each other out
-1=-x
1=x
Now to check the answer works.
2=3-√1*1
2=3-√1
2=3-1

(conversion factors and equivalent rates homework by the way)
Answer: conversion factor is just how much of it is in another unit
Step-by-step explanation:
for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.
Original rate (15 miles) x conversion factor (5280 feet are in a mile)
So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd

Answer: Z=14
Step-by-step explanation:
Simplify the equation: 1/4z=7/2
then multiple both sides by 4:
4 (1/4) = 4 (7/2)
z= 14
Answer: z=14
Step-by-step explanation: very easy
1/4z = 3 1/2 Divide each side by 1/4 to isolate z
3 1/2 will be divided by 1/4
How to divide 3 1/2 by 1/4?
Keep, change, flip.
First: Convert 3 1/2 to an improper fraction which is 7/2
Second: 7/2 / 1/4 keep 7/2
7/2 x 1/4 change from dividing to multiplying
7/2 x 4/1 flip 1/4 around to make it 4/1
28/2 multiply and then simplify to 14.
so the answer is 14

Use a net to find the surface area. The area of the right triangular prism is [blank] cm2.
Answer: The answer is 255 cm2
Step-by-step explanation:
So we are looking for the area of the right triangular prism. We first must start of by observing the lengths of each side. Once you have found out what is what multiply in order. First 12 x 5 = 60. Then multiply 13 x 15 which equals = 195. Finally you want to ad up the sums together to get 255 cm2.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Here are the pairs matched with their products:

- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Determine the distance between the points (−2, −4) and (−7, −12).
square root of 337 units
square root of 109 units
square root of 89 units
square root of 13 units
Answer: square root of 89 units i think so
Step-by-step explanation:
The distance between the points (−2, −4) and (−7, −12) is √89 units.
Among the given options, the correct answer is "square root of 89 units."
To determine the distance between the points (−2, −4) and (−7, −12), we can use the distance formula. The distance formula calculates the distance between two points (x₁, y₁) and (x₂, y₂) in a Cartesian coordinate system.
The distance formula is given by:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
Let's substitute the coordinates of the given points into the formula:
d = √((-7 - (-2))² + (-12 - (-4))²)
= √((-7 + 2)² + (-12 + 4)²)
= √((-5)² + (-8)²)
= √(25 + 64)
= √89

What is the value of x in this triangle? What is the value of each angle?
Answer:
x=17
Step-by-step explanation:
we know the 25 + 90 = 115 so we need the other one to make it 180 degrees.
180-115= 65
so we need 65 more degrees to get 180
now 3x + 11= 65 first step subtract 11 on both sides
you now get 3x = 54 then 2nd step is divide 3 on both sides
and now you get x=17 so
Answer:
Step-by-step explanation:
The entire value of the triangle is 180 degrees.
If you subtract 25 from 180 you are left with 155
Then Subtract 90 from 155 which will leave you with 65
Go on to subtract 11 from 65 having to be with 54 degrees left
Finally you will dived 54 by 3 and you are left with 18
3 x 18 = 54
54 + 11 = 65
Therefore x will equal to 65 degrees
