Find the missing side lengths leave your answers as radicals in simplest form
Answers
Answer:
14
Step-by-step explanation:
To find x, you will need to use sine. If you want to find y, use cosine:
sin 45 = x / 14 sqrt(2)
x = 14
(Since this is a 45 45 90 special triangle, x and y have the same length)
Since I talk about special triangles, 45 45 90 triangles are very simple:
To find the other two side lengths, just divide the hypotenuse by sqrt 2
14 sqrt(2) / sqrt(2) = 14
So both ways will still lead to 14

Answer:
7953.873
Step-by-step explanation:
The first derivative is ...
f'(x) = 4·3x²·e^x +4x³·e^x = e^x(4x³ +12x²)
Then the second derivative is ...
f''(x) = (12x² +24x)e^x +(4x³ +12x²)e^x
f''(x) = e^x(4x³ +24x² +24x)
So, f''(3) = (e^3)(4·27 +24·9 +24·3) = 396e^3 = 7953.87262158
Rounded to thousandths, this is ...
f''(3) = 7953.873

f''(x) ≈ 7953.87

19. Brian bought a new jacket at a discount of 30%. If the original price was $65, how much did Brian pay for the jacket?
Answers
Answer:45.5
Step-by-step explanation:
65•30%=19.5
65-19.5=45.5
Cost of the jacket with the discount is given by the equation A = $ 45.50
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the jacket with the discount be A
Now , the equation will be
The cost of the jacket = $ 65
The discount percentage =30 %
So , the discount amount = ( 30/100 ) x 65
The discount amount = 0.3 x 65
The discount amount = $ 19.50
Now , the cost of the jacket with the discount A = cost of the jacket - discount amount
Substituting the values in the equation , we get
The cost of the jacket with the discount A = 65 - 19.50
The cost of the jacket with the discount A = $ 45.50
Hence , the cost is $ 45.50

If its the bottom right it's 90°
If it's the bottom left it's 48°
Step-by-step explanation:
Ok so first, the triangle is a right triangle
meaning there's a 90° angle
Great, We now know two angles
90° and 42°
All angles of a triangle add up to 180
so we make it into an equation
and solve it.
42 + 90 + 6x = 180
132 + 6x = 180
-132 -132
6x = 48
Divide by 6 to leave x by itself.
x = 8
Now we can see what 6x actually is
6 ( 8 ) = 48
Note: This is for the bottom left angle. 6x

The mayor of a town has proposed a plan for the annexation of a new bridge. A political study took a sample of 900 voters in the town and found that 42% of the residents favored annexation. Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is above 38%. State the null and alternative hypotheses.
Answers
Answer:
H0 : p ≤ 0.38
H1 : p > 0.38
Step-by-step explanation:
Given :
Claim : percentage of residents who favor annexation is above 38%
The claim in the context here is the alternative hypothesis ; since the null and the alternative are always the opposite, then the ;
The null hypothesis : percentage is less than equal to 38%
The alternative hypothesis ; percentage is greater than 38%
Null hypothesis H0 : p ≤ 0.38
Alternative hypothesis H1 : p > 0.38
