If tan fº = 2/1 and the measure of yw is 8 units, what is the measure of xw?
2units
4units
7units
8 units
*see attachment for the figure referred to
Answer:
4 units
Step-by-step explanation:
Given that [tex] tan(f) = \frac{2}{1} [/tex], therefore, it follows that:
[tex] tan(f) = \frac{opp}{adjacent} = \frac{YW}{XW} = \frac{8}{XW} [/tex],
If the ratio of YW to XW = 2:1, therefore, [tex] \frac{2}{1} = \frac{8}{XW} [/tex]
Cross multiply to find XW
[tex] XW*2 = 8*1 [/tex]
[tex] XW = \frac{8}{2} = 4 units[/tex]

the height of the cylinder is 40 meters
Step-by-step explanation:
Use the formula they give you for the volume, and the fact that it has to equal 1000 [tex]\pi[/tex] cubic meters. Recall also that the cylinder's radius is 5 meters:
[tex]Vol=\pi\,R^2\,h\\1000\,\pi= \pi\,(5)^2 \,h\\1000\,pi=\,\pi\,25\,\,h\\h=1000\,\pi/(25\,\pi)\\h=40 \,\,m[/tex]
Which statement is true about the end behavior of the function represented by the graph?
As x approaches 1, f(x) approaches 25.
As x approaches −∞, f(x) approaches −∞, and as x approaches ∞, f(x) approaches −∞.
As x approaches −∞, f(x) approaches −4, and as x approaches ∞, f(x) approaches 7.
As x approaches −∞, f(x) approaches −∞, and as x approaches ∞, f(x) approaches ∞.
End behavior always involves x approaching positive and negative infinity. So we'll cross off the choice that says "x approaches 1".
The graphs shows both endpoints going down forever. So both endpoints are going to negative infinity regardless if x goes to either infinity.
Answer: Choice BAs x approaches −∞, f(x) approaches −∞, and as x approaches ∞, f(x) approaches −∞.Another way to phrase this would be to say "f(x) approaches negative infinity when x goes to either positive or negative infinity"
End behavior always involves x approaching positive and negative infinity. So we'll cross off the choice that says "x approaches 1".
The graphs shows both endpoints going down forever. So both endpoints are going to negative infinity regardless if x goes to either infinity. (Option B)
What is end behavior in graphs?End behavior refers to the behavior of a graph as the x-values approach positive or negative infinity.
It describes how the graph behaves at the far left and far right ends.
End behavior can be categorized as increasing or decreasing, and it helps understand the long-term trend or direction of the graph.

Given that (y+2), (y+3)and (2y^2+1) are consecutive terms of an arithmetic progression find the value of x
Answer:
In an arithmetic sequence, the difference between any consecutive terms should be always the same, then we have:
(y + 3) - (y + 2) = D
(2*y^2 + 1) - (y + 3) = D.
From the first equation, we can find the value of D:
y + 3 - y - 2 = D
1 = D.
Replacing this in the second equation, we have:
(2*y^2 + 1) - (y + 3) = 1
Now we can solve this equation:
2*y^2 + 1 - y - 3 - 1 = 0
2*y^2 - y - 3 = 0.
The solutions of this quadratic equation can be found with the Bhaskara's equation:
[tex]y = \frac{1 +- \sqrt{1^2 - 4*2*(-3)} }{2*2} = \frac{1+-\sqrt{25} }{4} = \frac{1+-5}{4}[/tex]
Then the possible values of y are:
y = (1 + 5)/4 = 6/4
y = (1 - 5)/4 = -1
The direction angle of a vector is 135o. The x-component of the vector is -3. What is the y-component of this vector
Answer:
3
Step-by-step explanation:
the vector somewhat looks like this:
^
_\|_ the angle is 135 degrees, and the x component is -3
| To find the y component given the direction angle and x component, use the formula y_comp = tan(angle) * x_comp
tan (135 degrees) * -3 = 3
You can also use the graph and geometry, but that method is not recommended for beginners as it is very easy to make a mistake. The graph should be used to check if your answer makes sense.

39. An adult male Western Banded Gecko is 5 1/2 (or 5.5) inches long.
41. 13,000 feet long, because 1 4/9 of 9,000 is 13,000.
43. to answer the question we need to know if 35 out of 50 states is equal or greater than 3/4 if that is the case, the Constitution will be ammended, and that is represented like this:
35/50 >= 3/4
that inequality is saying that 35 states out of 50 is equal or greater than 3/4, lets simplify and modify the fractions to compare easily:
35/50 >= 3/4
7/10 >= 3/4
now we need to find the least common multiplier of 10 and 4 to take the fractions to a common denominator and compare easy. Lets multiply numerator and denominator for a correct number to get the fractions to denominator common 20, the lcm:
7/10 >= 3/4
(2/2)(7/10) >= (5/5)(3/4)
2*7/2*10 >= 5*3/5*4
14/20 >= 15/20
we can see that the inequality does not hold, so,
35/50 >= 3/4
does not hold either, therefore the Constitution cannot be ammended

Step-by-step explanation:
Since a negative times a negative is positive, -(-1) becomes + 1 so the expression becomes -2/9 + 1. Using the commutative property of addition (a + b = b + a), we can rewrite this as 1 - 2/9. 1 = 9/9 so the expression becomes 9/9 - 2/9 = 7/9.
Which angle measures are correct? Select three options,
OmZX= 55°
OmZW = 125°
OmZW = 55°
mZZ = 125°
mZZ = 55°
PLEASE ANSWER FAST TIMED TEST
Answer:
m∠W = 125°
m∠X = 55°
m∠Z = 55°
Step-by-step explanation:
The shape is parallelogram WXYZ. m∠Y = 125.
A parallelogram is a quadrilateral shape in which both opposite sides and opposite angles are equal to each other. The diagonals of a parallelogram bisect each other. Also consecutive angles in a parallelogram are supplementary.
Therefore in parallelogram WXYZ:
m∠Z + m∠Y = 180° (Consecutive angles in a parallelogram are supplementary)
m∠Z + 125 = 180
m∠Z = 180 - 125
m∠Z = 55°
m∠W = m∠Y (Opposite angles are equal)
m∠W = 125°
m∠W + m∠X = 180° (Consecutive angles in a parallelogram are supplementary)
m∠X + 125 = 180
m∠X = 180 - 125
m∠X = 55°
What is The equation of the line that passes through the point (4,8) and has a slope of 0
Answer:
y = 8
Step-by-step explanation:
Plug in the point and slope into the equation y = mx + b to solve for b:
8 = 0(4) + b
8 = b
Then, plug this back into the equation:
y = 0x + 8
y = 8 will be the equation
Answer: y=8
Step-by-step explanation:
concept to know: when it is a horizontal line, the slope is zero, when it is a vertical line, the slope is undefined.
---------------------
If it is required to have a slope of 0, then it is a horizontal line.
y=b (this is the equation for some line that slope is 0)
We then should find the b, or the y-intercept
The question did not provide us with a point of y-intercept, BUT since it is a horizontal line, the y value of any point is the same, including y-intercept (when x value is 0)
Therefore, the y-intercept will be (0, 8), and the equation will be
y=8

Step-by-step explanation:
we have to find a number that gives a remainder of 1 when divided by both 2, 3 and 5.
The easiest way to do this is to list the factors of 5, add 1 to it, and test them until we find the one with a remainder of 1 by all three divisors. This is done as follows:
1) factor: 5 (+1) = 6
6 ÷ 2 = 3 remainder 0
6 ÷ 3 = 2 remainder 0
since there is a remainder of 0, when divided by 3, 6 is wrong
2) factor; 10 (+1) = 11
11 ÷ 3 = 3 remainder 2 ( 11 is not the correct answer
3) factor : 15 (+1) = 16
16 ÷ 2 = 8 remainder 0 ( 16 is not the correct answer
4) factor : 20(+1) = 21
21 ÷ 3 = 7 remainder 0 ( 21 is wrong)
5) factor : 25(+1) = 26
26 ÷ 2 = 13 remainder 0 ( 26 is wrong)
6) factor : 30(+1) = 31
31 ÷ 2 = 15 Remainder 1
31 ÷ 3 = 10 Remainder 1
31 ÷ 5 = 6 Remainder 1
since all three divisors give a remainder of 1, the correct answer is 31
Therefore you have 31 pwnnies

1 Let a = 5.2 and b = 4.7.
a Find the exact value of 3a + b3.
Xena estimates that the answer to part a is 140.
b Find the percentage error made by Xena in her estimation.
Part (a)
Replace every 'a' with 5.2 and replace every 'b' with 4.7
Then use your calculator to evaluate.
3a + b^3 = 3*5.2 + (4.7)^3 = 119.423
Answer: 119.423===============================================
Part (b)
The true value is 119.423 which is the result of part (a)
The estimated value is 140
Subtract the two values
140-119.423 = 20.577
and divide that over the true value
20.577/140 = 0.14697857142858
Which, when rounded to 4 decimal places, we get 0.1470

C (2) = 35+ 60x . Explain what C (5) = 335 means in terms of total cost and
number of hours.
help plz
Answer:
Step-by-step explanation:
Total cost
C (x) = 35+ 60x
Where,
Fixed cost= $35
Variable cost = 60x
x= number of hours of work
Total cost is the addition of fixed and variable cost
C (x) = 35+ 60x
C(5)= 35 + 60(5)
= 35 + 300
=335
C(5) = 335
C(5) = 335 is Olivia's total cost of hiring the electrician
x=5 is the electrician's number of hours of work
35= fixed cost of hiring the electrician
60(5) = 300 is the variable cost of hiring the electrician for 5 hours
