Prove that
sec A cosec A - cotA= tan A.
Can someone’s please help me with this one.. I’ll give brainliest
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
secx = [tex]\frac{1}{cosx}[/tex] , cosecx = [tex]\frac{1}{sinx}[/tex]
cotx = [tex]\frac{cosx}{sinx}[/tex] , tanx = [tex]\frac{sinx}{cosx}[/tex]
Consider the left side
secA cosecA - cotA
= [tex]\frac{1}{cosA}[/tex] × [tex]\frac{1}{sinA}[/tex] - [tex]\frac{cosA}{sinA}[/tex]
= [tex]\frac{1}{cosAsinA}[/tex] - [tex]\frac{cosA}{sinA}[/tex]
= [tex]\frac{1-cos^2A}{cosAsinA}[/tex]
= [tex]\frac{sin^2A}{cosAsinA}[/tex] ( cancel sinA on numerator/ denominator )
= [tex]\frac{sinA}{cosA}[/tex]
= tanA = right side ⇒ proven

Answer:
[tex]a_{n}[/tex] = 4n + 4
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence.
d = 12 - 8 = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 4 , then
[tex]a_{n}[/tex] = 8 + 4(n - 1) = 8 + 4n - 4 = 4n + 4

The difference between the C.I. and S.I. calculated annually on ₹ 625 at 10 % per
annum for 1 year is:
Answer:
R0
Step-by-step explanation:
Given the following data;
Principal, P = R625
Time, t = 1 year
Rate, r = 10% = 10/100 = 0.1
To find compound interest;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Substituting into the equation, we have;
[tex] A = 625(1 + \frac{10}{100})^{1}[/tex]
[tex] A = 625(1 + 0.1)[/tex]
[tex] A = 625(1.1)[/tex]
A = 687.5
Therefore, C.I = A - P
C.I = 687.5 - 625
C.I = 62.5
To find the simple interest;
[tex] S.I = \frac {PRT}{100} [/tex]
[tex] S.I = \frac {625 *10*1}{100} [/tex]
[tex] S.I = \frac {6250}{100} [/tex]
S.I = 62.5
Now to find the difference;
Difference = C.I - S.I
Difference = 62.5 - 62.5
Difference = R0

Two sides are congruent to each other.
The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
A triangle with all sides of different lengths. All angles are different, too. So no sides are equal and no angles are equal.

Sal invests $16,000 at age 35. He hopes the investment will be worth $320,000 when he turns 40. If the interest compounds continuously, approximately what rate of growth will he need to achieve his goal? Round to the nearest tenth of a percent.
59.9%
Sorry I don’t have time to explain in the middle of an exam
The rate of growth needs to be 59.9%.
The formula used to determine the future value of an investment when interest is compounded continuously is:
FV = A x [tex]e^{r}[/tex] x N
A= amounte = 2.7182818 N = number of years r = interest rateFV = future value$320,000 = $16,000 x [tex]e^{r}[/tex] x 5
Divide both sides by $16,000
20 = 5[tex]e^{r}[/tex]
Take the In of both sides
In(20) = 5r
Divide both sides by 5
r = 59.9%

A canteen spends money on food and drink in the ratio of 29:3
In total, they spend £6496.
Find how much money they spend on drink.
Answer:
Money spend on drink = £ 609
Step-by-step explanation:
Food : drink = 29 : 3
Money spend on food = 29x
Money spend on drink = 3x
Total money spend = 29x + 3x = 32x
32x = £6496
x = 6496/32
x = £ 203
Money spend on drink = 3x = 3 * 203 = £ 609
