If cosθ=3/5, find tanθ
Answer and step-by-step explanation:
cos = adj/hyp (in a right triangle)
cos0 = 3/5
adj = 3
hyp = 5
opp = sqrt( 5^2 - 3^2) = sqrt( 25-9) = sqrt(16) = 4 (Pythogorean theorem)
tan0 = opp/adj = 4/3
Answer:
[tex]\boxed {\boxed {\sf tan( \theta)=4/3}}[/tex]
Step-by-step explanation:
Cosine is equal to adjacent over hypotenuse.
cos(x)=adjacent/hypotenuseWe are given: cosθ=3/5
Therefore, the adjacent is 3 and the hypotenuse is 5.We want to find tanθ. Tangent is equal to opposite over adjacent.
We need to find the other leg of the triangle, which is the "opposite". Use Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
The hypotenuse (c) is 5.
[tex]a^2+b^2=5^2[/tex]
One leg (a) is 3, the other (b) is unknown.
[tex]3^2+b^2=5^2[/tex]
Evaluate all the exponents.
[tex]9+b^2=25[/tex]
Subtract 9 from both sides of the equation.
[tex]9-9+b^2=25-9[/tex]
[tex]b^2=16[/tex]
Take the square root of both sides.
[tex]\sqrt{b^2} =\sqrt{16}[/tex]
[tex]b=4[/tex]
Now we know the "opposite" is 4. We can find the tangent now.
[tex]tan(x)=opposite/adjacent[/tex] (opposite=4, adjacent=3)
[tex]tan( \theta)=4/3[/tex]
The tangent of theta is 4/3

Hermina cut a ft by ft piece of plywood down the diagonal.
A rectangle is 4 feet wide and 8 feet long. A diagonal cut is shown with a line labeled c. The cut divides the rectangle in half and creates two right triangles. The hypotenuse of each right triangle is the line labeled c.
What is the length c of the cut, in feet?
Answer:
[tex]\sqrt{80} = c[/tex] is the answer.
Step-by-step explanation:
We can solve this using the Pythagorean theorem.
We know we can use the pythagorean theorem because it has a 90 degree angle.
[tex]a^{2}+ b^{2}= c^{2}[/tex]
We are given the sides 4 and 8.
[tex]4^{2} + 8^{2} = c^{2}[/tex]
[tex]80 = c^{2} \\\\\sqrt{80} = c[/tex]

Every year on November 1, the Stablo family plants a tree. This tradition has
happened for generations and the first tree the family planted is now 183 years
old. Two of the trees were planted in their backyard; one is an apple tree and the
other is a maple tree. The maple tree is older than 100, but was not the first tree
planted. On November 1 of this year, the age of the maple tree is fifteen times
the age of the apple tree.
On November 1 of some year from now, the age of the maple tree will be eleven
times the age of the apple tree. How old are the trees that year?

Solve for x.
14 = 28 + 7x
Answer:
X = 2
Step-by-step explanation:
14= 28 + 7x
28 - 14 = 7x
14 = 7x
14 / 7
2 = x
Answer:
x = − 2
Step-by-step explanation:
The random variable X is known to be uniformly distributed between 2 and 12. Compute E(X), the expected value of the distribution.
Answer:
The expected value of the distribution is 7.
Step-by-step explanation:
The random variable X is known to be uniformly distributed between 2 and 12.
The probability density function of X is:
[tex]f_{X}(x)=\frac{1}{b-a};\ a<X<b[/tex]
Here a = 2 and b and 12.
Compute the expected value of the distribution as follows:
[tex]E(X)=\frac{a+b}{2}[/tex]
[tex]=\frac{2+12}{2}\\\\=\frac{14}{2}\\\\=7[/tex]
Thus, the expected value of the distribution is 7.

[tex](8x - 8) + {100}^{\degree} = {180}^{\degree} [/tex]
[tex]\implies8x - 8 = 180 - 100[/tex]
[tex]\implies8x - 8 = 80[/tex]
[tex]\implies8x = 80 + 8[/tex]
[tex]\implies8x = 88[/tex]
[tex]\implies x = \frac{88}{8} [/tex]
[tex]\implies x = 11 \: (a)[/tex]
Why did we used the equation "(8x - 8) + 100° = 180°" to find x?
Because, sum of interior angle in the same side of two parallel lines are always equal to 180°.
Don't forget to give the "°" symbol ;)

State if the triangles in each pair are similar. If so, state how you know they are similar.
Answer:
A) similar; SAS similarity.
Step-by-step explanation:
SAS Triangle Similarity
The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar.
We are given two triangles BCD and JKL. Sides DB and JL have a ratio of 90/20 = 4.5
Sides JK and BC have a ratio of 81/18 = 4.5
Since both sides are proportional and their included angle of 43° are congruent, then both triangles are similar, SAS similarity.
A) similar; SAS similarity.

Beth is making a rope ladder each step of the ladder is 2 1/3 feet wide width as a rope that is 21 feet long how many steps can she make from the rope
Answer:
Answer: She can make 9 steps from the rope.
Step-by-step explanation:
Given : The width of each step of the ladder = 2\dfrac{1}{3}\text{ feet}2
3
1
feet = \dfrac{2(3)+1}{3}=\dfrac{7}{3}\text{ feet}
3
2(3)+1
=
3
7
feet
The length of the rope = 21 feet
Then , the number of required steps = ( length of the rope ) ÷ (width of each step of the ladder)
=21\div\dfrac{7}{3}=21÷
3
7
=21\times\dfrac{3}{7}=3\times3=9=21×

=3×3=9
Hence, the number of steps can she make from the rope = 9.

A newspaper ran a story concerning the increasing prices of mobile phones. The story stated that mobile phone prices dropped a few years ago, but now are beginning to increase in price because of added features.
• According to the story, the average price of all mobile phones a few years ago was £215.
• A large random sample of mobile phones (n = 200) was taken, and their prices recorded.
• We wish to use a hypothesis test to determine if the average price of all mobile phones is now greater than £215.
Required: Define the hypotheses, and with reference to the applicable random variable distribution, find the rejection region appropriate for this test if we are using the significance level α = 0.05.
Answer:
H0 : μ = 215
H1 : μ > 215
Rejection region :
Zstatistic > Z0.05
Step-by-step explanation:
Given that:
Average price of all mobile phones was £215
Sample size = 200
Significance level (α) = 0.05
To determine if the average price of all mobile phones is now greater than £215
The Null hypothesis (H0) :
H0 : μ = 215
Alternative hypothesis (H1) :
H1 : μ > 215
The rejection region :
|Zstatistic > Zα|
α = 0.05 ; Z0.05
Rejection region :
Zstatistic > Z0.05

1. Approximately what was the total expenditure on entertainment if separated amount of $11,406.30, $1,669.72, $2,506.81 and $1,930.20 were spent?
Answer:
The approximate expenditure spent on entertainment is $17,513
Step-by-step explanation:
To get the total entertainment expenditure, we simply add up all these values
We have;
11,406.30 + 1669.72 + 2506.81 + 1930.20 = 17,513.03
The total expenditure spent on entertainment is approximately $17,513

PLEASEEEEEEEEEEEEEE NO FAKE ANSWERS OR YOU GET NO BRAIN CROWN AND REPORTED EXPLAIN PLEASE DUE IN FEW MINUTES :)))
Answer:
FalseStep-by-step explanation:
Actual question is:
logf 4(3d) + log4 1 = log4 3dSolution:
logf 4 + logf (3d) + 0 = log4 (3d)logf 4 + logf (3d) = log4 (3d)If we assume f = 4, then
log4 4 + log4 (3d) = log4 (3d)log4 4 = 0but log4 4 = 1
1 = 0 is impossibleTherefore the statement is False
