Answer:
b = 13√3
c = 26
Step-by-step explanation:
tan 30 = a /b
b = a/ tan 30 = 13 / (1/√3) = 13√3
sin 30 = a /c
c = a/ sin 30 = 13 / (1/2) = 13 * 2 = 26

f (x) =-3x+25; Find f(x)=52
Answers
Simplifying
-3x + 25 = 52
Reorder the terms:
25 + -3x = 52
Solving
25 + -3x = 52
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-25' to each side of the equation.
25 + -25 + -3x = 52 + -25
Combine like terms: 25 + -25 = 0
0 + -3x = 52 + -25
-3x = 52 + -25
Combine like terms: 52 + -25 = 27
-3x = 27
Divide each side by '-3'.

(a) How many miles did Chloe travel from time t = 0 to time t = 2 ?

Do not write beyond this border.
Answers
Answer:
Step-by-step explanation:
a) ∫from 0 to 2 of te^(4-t^2) dt. Let u = 4-t^2. du= -2dt. And, tdt= -dy/2.
If x=0, u= 4 and if x=2, u=0.
Therefore our new integral will be, -(1/2) ∫ from 0 to 4 of e^u du.
= -(1/2)(e^u) | 0 to 4
= -(1/2)(e^0 - e^4)
= -(1/2) + (1/2)e^4
= (1/2)(e^4 -1) miles
Therefore, from t=0 to t=2, Chloe has travelled a distance of (1/2)(e^4-1) miles.
b) At t=3, C(t)=12-3t-t^2
C(t) is already a function of velocity so simply plug in C(3), which is -6 miles/hour.
We also need to know acceleration.
C'(t)= -3 - 2t
C(3)= - 9 miles/hour squared.
Therefore, since velocity and acceleration are both negative, Chloes speed is increasing at t =3 hours.

At a tournament, the bowling league is providing 160 sandwiches for its members. The table shows the number of different types of sandwiches that were ordered. The ratio of turkey sandwiches to roast beef sandwiches is 5:3. Drag the numbers to complete the table.
Answers
Answer: See below
Step-by-step explanation:
The total number of ordered sandwiches is 160
The total number of Turkey Sandwiches is 80
The ratio of Turkey to Roast Beef is 5:3
So from this, 5 times of a value is 80
So 5x = 80
And x = 16
So the Roast beef sandwiches are 16×3=48
Therefore, the table is:

A two-sided test of H0: μ=0, α=0.05 (two sided), yields a p-value of 0.19. Will the 95% confidence interval for μ include 0?
Group of answer choices
No
Unknown
Yes
Answers
Explanation
Rule: if the p-value is smaller than alpha, then we reject the null.
We're given a p-value of 0.19 and alpha = 0.05
Based on that rule, it means we fail to reject the null (i.e. "accept" the null), since the p-value is not smaller than alpha.
Therefore, we conclude that mu = 0 must be the case, which means this value is in the confidence interval.
If mu = 0 was outside the confidence interval, then we would reject the null.

Answers
Answer:60.97
Step-by-step explanation: tan 49 = opposite/adjacent = x/53
tan 49 = x/53
tan 49/1 = x/53
53 tan 49 = x
x = 60.969
x = 60.97
The height of tree is 60.97 feet tall on the ground is 53 feet from the tree.
What is a trigonometric function?Trigonometry uses the first six fundamental trigonometric functions. Trigonometric proportions are these functions. The six fundamental trigonometric functions are the sin function, cosine function, secant function, and so on.
As per the data given in the question,
tan 49° = opposite/adjacent
tan 49° = x/53
tan 49/1 = x/53
x = 53 tan 49°
x = 60.969 or,

Based on the supply and demand of the baseball caps, the relevant supply quantities are:
a. 20,000 baseball caps. b. 60,000 baseball caps.c. 30,000 baseball caps. d. 40,000 baseball caps. What quantity of baseball caps will be supplied domestically?At the price of €2, the supply according to the graph is:
= 20,000 baseball caps.
What quantity will be imported?The quantity imported is shown as:
= Demand at €2 - Domestic supply at €2
= 80 - 20
= 60,000 baseball caps
What quantity will be supplied domestically with the tariff?A tariff of €1 would increase the price to €3.
At this price, the supply would be:
= 30,000 baseball caps.
At the new price, the quantity imported is:
= Demand at €3 - Domestic supply at €3
= 70,000 - 30,000
= 40,000 baseball caps.

there are two congruent angles that are between a congruent line segment.
The angles in a quadrilateral are 4y - 10°, y + 40°, 3y + 20° and 2y + 10° in order as you go around the quadrilateral.
a) Set up and solve an equation, to find the value of y.
b) Hence work out the value of each angle.
c) What type of quadrilateral is this?
Answers
Answer:
see explanation
Step-by-step explanation:
the sum of the interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360
4y - 10 + y + 40 + 3y + 20 + 2y + 10 = 360 , that is
10y + 60 = 360 ( subtract 60 from both sides )
10y = 300 ( divide both sides by 10 )
y = 30
then 4 angles are
4y - 10 = 4(30) - 10 = 120 - 10 = 110°
y + 40 = 30 + 40 = 70°
3y + 20 = 3(30) + 20 = 90 + 20 = 110°
2y + 10 = 2(30) + 10 = 60 + 10 = 70°
Since the angles measures are in order around the quadrilateral, then
the opposite angles are congruent, thus quadrilateral is a parallelogram
