What is the identity of (sec^2theta-1)/sintheta = sintheta/(1-sin^2theta)
Please get this done and match the sides. Thank you!
Answer:
See Below.
Step-by-step explanation:
We want to prove the trigonometric identity:
[tex]\displaystyle \frac{\sec^2(\theta)-1}{\sin(\theta)}=\frac{\sin(\theta)}{1-\sin^2(\theta)}[/tex]
To start, let's simplify the right side. Recall the Pythagorean Identity:
[tex]\sin^2(\theta)+\cos^2(\theta)=1[/tex]
Therefore:
[tex]\cos^2(\theta)=1-\sin^2(\theta)[/tex]
Substitute:
[tex]\displaystyle \frac{\sin(\theta)}{1-\sin^2(\theta)}=\frac{\sin(\theta)}{\cos^2(\theta)}[/tex]
Split:
[tex]\displaystyle =\frac{\sin(\theta)}{\cos(\theta)}\left(\frac{1}{\cos(\theta)}\right)=\tan(\theta)\sec(\theta)[/tex]
Therefore, our equation becomes:
[tex]\displaystyle \frac{\sec^2(\theta)-1}{\sin(\theta)}=\tan(\theta)\sec(\theta)[/tex]
From the Pythagorean Identity, we can divide both sides by cos²(θ). This yields:
[tex]\displaystyle \tan^2(\theta)+1=\sec^2(\theta)[/tex]
So:
[tex]\tan^2(\theta)=\sec^2(\theta)-1[/tex]
Substitute:
[tex]\displaystyle \frac{\tan^2(\theta)}{\sin(\theta)}=\tan(\theta)\sec(\theta)[/tex]
Rewrite:
[tex]\displaystyle (\tan(\theta))^2\left(\frac{1}{\sin(\theta)}\right)=\tan(\theta)\sec(\theta)[/tex]
Recall that tan(θ) = sin(θ)/cos(θ). So:
[tex]\displaystyle \frac{\sin^2(\theta)}{\cos^2(\theta)}\left(\frac{1}{\sin(\theta)}\right)=\tan(\theta)\sec(\theta)[/tex]
Simplify:
[tex]\displaystyle \frac{\sin(\theta)}{\cos^2(\theta)}=\tan(\theta)\sec(\theta)[/tex]
Simplify:
[tex]\tan(\theta)\sec(\theta)=\tan(\theta)\sec(\theta)}[/tex]
Hence proven.

Answer:
Angles B & C both = 157 degrees .
Step-by-step explanation:
Angle A is adjacent to Angle B, which means they are the same size. 23 degrees for A & B.
23+23 = 46.
We have two straight lines, one line = 180. 180*2 = 360.
Take 46 from 360 because we already figured out two angles.
360 - 46 = 314
Divide 314 by 2 because we have two unknown angles...
314 / 2 = 157 .
Angle B & C = 157.

Step-by-step explanation:
A simile is a figure of speech that directly compares two things. Similes differ from other metaphors by highlighting the similarities between two things using comparison words such as "like", "as", "so", or " than", while other metaphors create an implicit comparison.

Suppose the sequence {an} is arithmetic with a3 = 15, d = -3/2, and an=6
Find n.
Answer:
The value of n = 9th term
Step-by-step explanation:
Given:
In an arithmetic series
a3 = 15
d = -3/2
an = 6
Find:
The value of n
Computation:
In an arithmetic series
An = a + [n - 1]d
where,
An = last term
a = first term
n = number of term
d = common difference
So,
a3 = a + 2d
15 = a + 2(-3/2)
15 = a - 3
a = 18
An = a + [n - 1]d
6 = 18 + [n - 1][-3/2]
-12 = [n-1][-3/2]
8 = n - 1
The value of n = 9th term
What is the measure of ∠B?
Triangle A B C with ray A G through point C and angle measures A = 3x, B = 4x, and exterior angle B C G = 10x minus 45.
60∘60 degrees
15∘15 degrees
45∘45 degrees
105∘
Answer:
Solution given:
4x+3x=10x-45[exterior angle is equal to the sum of two opposite interior angle]
45=10x-7x
x=45/3
x=15
now.
<B=4x=4×15=60° is your answer
The required measure of ∠B is 60° for the given triangle.
What is the Exterior Angle?An exterior Angle is defined as an angle produced on the outside of a polygon by extending the sides of the polygon.
According to the shown figure, we have:
The external angle is ∠BCG = 10x - 45.
And, two interior angles as ∠A = 3x, and ∠B = 4x.
As we know that the sum of two opposite interior angles equals the exterior angle.
So, we can be written as follows:
4x + 3x = 10x - 45
45 = 10x - 7x
x = 45/3
x = 15
So, the measure of ∠B is:
∠B = 4x
∠B = 4 × 15
∠B = 60°
Thus, the required measure of ∠B is 60°.

56 times a number minus 13 is equal to 6 less than the number.
Step 1 of 2: Write out the equation.
Answer:
The equation is 56x - 13 = x - 6
Step-by-step explanation:
Let's say our 'number' is x. If it says it's 56 times our number, it's 56x. Minus 13, which is 56x - 13. If it is equal than 6 less than the number, then it is x - 6.
So the equation is 56x - 13 = x - 6

does the graph of this equation widen or narrow from the parent function? g(x)=3/4(x-5)^2+12
9514 1404 393
Answer:
widen
Step-by-step explanation:
The vertical scale factor is 3/4, so the vertical extent is shortened at a given x-value distance from the axis of symmetry. That will give the appearance of making the parabola (slightly) wider.

#CarryOnLearningDetermine the amplitude or period as requested. Amplitude of y=3 cos 1 2
Answer:
The amplitude is 3
Step-by-step explanation:
Given
The right function is:
[tex]y = 3 \cos(\frac{1}{2}x)[/tex]
Required
The amplitude
A sine function is represented as:
[tex]y =A \cos(Bx + C) + D[/tex]
Where
[tex]Amplitude = |A|[/tex]
By comparing:
[tex]y = 3 \cos(\frac{1}{2}x)[/tex] and [tex]y =A \cos(Bx + C) + D[/tex]
[tex]A= 3[/tex]
So:
[tex]Amplitude = |3|[/tex]

Past experience indicates that the time required for high school seniors to complete a standardized test is a normal random variable with a standard deviation of minutes. Test the hypothesis that against the alternative that if a random sample of the test times of high school seniors has a standard deviation . Use a level of significance.
Complete question :
Past experience indicates that the time required for high school seniors to complete a standardized test is a normal random variable with a mean of 35 minutes. If a random sample of 20 high school seniors took an average of 33.1 minutes to complete this test with a standard deviation of 4.3 minutes, test the hypothesis, at the 0.05 level of significance.
Answer:
We conclude they there is significant evidence to support the claim That time required for high school seniors to complete test is less than 35 minutes.
Step-by-step explanation:
H0 : μ = 35
H1 : μ < 35
Sample size, n = 20
Standard deviation, s = 4.3
xbar = 33.1
Test statistic :
T = (xbar - μ) ÷ (s /√n)
T = (33.1 - 35) ÷ (4.3 /√20)
T = - 1.9 ÷ 0.9615092
T = - 1.976
The Pvalue can be obtained from the test statistic using a Pvalue calculator :
Pvalue at 0.05 ; df = 19 is 0.0314
Since, Pvalue < α ; We reject the Null and conclude that time required for high school candidate to complete test is less than 35 minutes
A group of friends are dining at a pizza parlor. They have 1 1/2 pizzas. If each friend eats 1/4 of a pizza, how many friends can have an equal share?
Simplify your answer
Answer:
6 friends can share the pizza
Step-by-step explanation:
1 1/2 ÷ 1/4 =6
Answer:
Divide 1 1/2 by 1/4. Note that 1 1/2 = 1 2/4 = 6/4. So now we divide 6/4 by 1/4, obtaining 6.
6 friends can enjoy an equal share.
