Answer:
31.6°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the trig function relating the sides opposite and adjacent an acute angle in a right triangle. It tells you ...
Tan = Opposite/Adjacent
__
The tangent of angle B is ...
tan(B) = AC/CB
tan(B) = 28.2/45.8
The angle is found from the tangent using the inverse tangent function.
B = arctan(28.2/45.8) ≈ 31.621°
The measure of angle B is about 31.6°.

Which classification best represents a triangle with side lengths 10 in., 12 in., and 15 in.? acute, because 102 122>152 acute, because 122 152>102 obtuse, because 102 122>152 obtuse, because 122 152>102
The triangle with side lengths of 10 in., 12 in., and 15 in. is acute because 10^2 + 12^2 > 15^2
What is the acute angle?An acute angle is defined as the measure of an angle that is less than 90 degrees.
The side lengths of the triangles are 10, 12 and 15
The smallest side lengths are: 10 and 12
The sum of the squares of these side lengths is
[tex]10^2 + 12^2[/tex]
For the triangle to be acute, then the following must be true
[tex]10^2 + 12^2 > 15^2[/tex]
Evaluate the exponents
[tex]244 < 255[/tex]
The above inequality is true.
Hence, the triangle is acute because 10^2 + 12^2 > 15^2

(a) Is there convincing evidence at the a= 0. 05 significance level that this brand of toilet paper will
require less than 26 squares to absorb 1/4 cup of water?
(b) Referring to your conclusion, what type of error may have been made? Describe the error in the
context of this study.
There's no convincing evidence at 0.05 significance level that this brand of toilet paper will require less than 26 squares.
What is a significance level?A significance level simply means is the probability that an event has occured by chance.
In this case, there's convincing evidence at 0.05 significance level that this brand of toilet paper will require less than 26 squares to absorb 1/4 cup of water. Therefore, we fail to reject the null hypothesis.
A type of error that may have been made is type II error. This is the non rejection if the null hypothesis when it's false.

34-w=6 is the question I need answered.
w = 28
solving stepwise:
[tex]\dashrightarrow \sf \ \ 34-w=6[/tex]
[tex]\dashrightarrow \sf \ \ -w=6-34[/tex]
[tex]\dashrightarrow \sf \ \ -w=-28[/tex]
[tex]\dashrightarrow \sf \ \ w=28[/tex]
Answer:
w = 28Step-by-step explanation:
Given equation:
34 - w = 6Substact 6 both sides:
⇒ 34 - w = 6⇒ 34 - w - 6 = 6 - 6⇒ 28 - w = 0Subtract 28 both sides:
⇒ 28 - w = 0⇒ 28 - 28 - w = 0 - 28⇒ 0 - w = -28⇒ -w = -28Multiply -1 both sides:
⇒ -w = -28⇒ -w × -1 = -28 × -1⇒ w = 28Pls pls pls help ill give you whatever :(

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel.
How old is Kevin?
Answer:
kevin = 8 - hope this helped
:)
Step-by-step explanation:
Kevin = 4d Kevin is 4 times as old as Daniel
Kevin = d + 6 Kevin is 6 years older than Daniel
4d = d + 6 They both equal K, so they are equal
3d = 6 subtracts D from both sides
d=6/3 = 2
If Daniel is 2 then Kevin is 4x2=8
If Daniel is 2 then Kevin is 2+6 = 8
Kevin is 8
Daniel is 2

which graph represents the inequality y < 2x +3 correctly
Answer:
im not sure , sorry
Step-by-step explanation:
Answer:
Option C
Step-by-step explanation:
Graphing inequality:
1) First plot y = 2x + 3 as a dotted line as y is less than x
Put x = 0, y = 2*0 +3 = 0 + 3 = 3 ⇒ (0, 3)
Put x = 1 , y = 2*1 + 3 = 2 +3 = 5 ⇒(1 , 5)
Put x = -1, y =2*(-1)+3 ⇒ -2+3 = 1 ⇒ (-1,1)
Mark these three points, and draw a dotted line.
2) Shade the area bellow the dotted line as y < 2x + 3
Check: take a point in the shaded area. (1 , -1)
-1 < 2*1 + 3
-1 < 2 +3
-1 < 5
The condition is satisfied.

Who developed the system of binomial nomenclature?.
Answer:
The Correct A nswer Is... Carl Linnaeus
Step-by-step explanation:
The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 5 units, then what is the value of k?
k equals one fifth
k = 5
k equals negative one fifth
k = −5
Answer:
k = 5
Step-by-step explanation:
Plugging in 5 for k turns out positive 5 into a negative 5 because of the negative sign in the function. When k is negative, then the graph moves down.
For the function f(x)= √x-6 +1, find the inverse function.
Answer:
f^(-1) (x) = (x-1)²+6 x≥6
Step-by-step explanation:
y=√(x-6) +1 original for the inverse x and y switch places because you are rflecting the function over the line y=x
y=√(x-6) +1 now the job is solve for y by using inverse operations. Think about undoing the equation.
x-1=√(y-6) subtract 1
(x-1)²=y-6 square both sides of the equation
(x-1)²+6=y add 6 to both sides
x≥6 because we are only using real numbers and if x is less than 6 you get a negative number under the square root sign.
