Answer:
The equivalent expression is cosec2x
option B
Step-by-step explanation:
The correct question is ;
which expression is equivalent to sec2xcot2x?
Solution
Mathematically;
sec2x = 1/cos2x
cot2x = 1/tan2x
so we have
1/cos2x * 1/tan2x
recall that the product of tan and cos is sin
from the formula;
tan = sin/cos
so we have our final answer as;
1/sin2x
Kindly recall that ;
sin = 1/cosec
so therefore;
1/sin2x = csc2x

A series is defined by 5+9+13+17+.......+805 a. Find the number of terms of the series. b. Find the sum of the first 20 terms.
Answer: the number of terms of the series is 201 numbers
the sum of the first 20 terms is 890
the number of terms of the series is [tex]\frac{805-5}{4}+1=201[/tex]
the series have:
u1 = 5
d = 4
=> u(n) = 5 + 4.(n - 1)
=> u(20) = 5 + 19.4 = 81
so the sum of the first 20 terms is (81 + 5).20/2 = 890
( u1 is the first number of the series, d is the distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)

Mary bought 6 bracelets that cost the same amount and one necklace which cost $86. The items she bought totaled $254 before sales tax was added. What was the cost of each bracelet?
A) $14
B) $56
C) $42
D) $28
1 necklace will therefore cost 34/4 = $8.5
Step-by-step explanation:
She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.
At an average, she spent $49.
The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.
Thus $49 - $15 = amount spent on the 4 necklaces = $34.
4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5
Answer:
Step-by-step explanation:
6x+86=254
subtract 86 from both sides 6x=168
divide both sides by 6 x=28

Answer:
if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR
We conclude that 'Symmetric Property of Angle Congruence' illustrates this statement.
Step-by-step explanation:
We know that the Symmetric Property of Angle Congruence can be defined as
For any angles X and Y, if ∠X≅∠Y , then ∠Y≅∠XFor example, Let suppose
m∠X = 20m∠Y = 20As ∠X≅∠Y i.e. 20 ≅ 20
then
∠Y≅∠X i.e. 20 ≅ 20
Given
if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR
Thus, we conclude from the above discussion that 'Symmetric Property of Angle Congruence' illustrates this statement.
A truck travels 2,400 miles in 60 hours going the same distance each hour. How many miles does the truck travel each hour?
Answer:
The truck travels 40 miles per hour.
Step-by-step explanation:
[tex] \frac{2400 \: miles}{60 \: hours} = \frac{x}{1 \: hour} \\ \\ \frac{60x}{60} = \frac{2400}{60} \\ \\ x = 40[/tex]
Problem 1: Bob’s Citrus and Nursery sells cartons of citrus fruits. There are 24 oranges in each carton. They have 5,643 oranges to pack into cartons. How many cartons can they fill?
Problem 2: This year, 4,338 grapefruits have been harvested so far. Bob’s has 18 storage bins for grapefruits. If the grapefruits are distributed evenly among 18 bins, how many grapefruits are in each bin?
248 per bin.
The number of cartons that the oranges would fill in Bob’s Citrus and Nursery would be 235 cartons.
The number of grapefruits in each bin would be 241 grapefruits per bin.
How to find the number of cartons ?To find the number of cartons of oranges that would be filled, use the number of oranges that go into carton in Bob’s Citrus and Nursery and the number of oranges they have to pack. The formula would be:
= Number of oranges / Number of oranges per carton
= 5, 643 / 24
= 235 cartons
How to fin the number of grapefruits per bin ?The same logic is applied to find the number of grapefruits that would be in each bin. If each bin would have an equal number of grapefruits, the number of grapefruits per bin would be:
= Number of grapefruits / Number of bins
= 4, 338 / 18
= 241 grapefruits per bin

Consider a large population with a mean of 100 and a standard deviation of 21. A random sample of size 36 is taken from this population. The standard error of the sampling distribution of sample mean.
Answer:
3.5
Step-by-step explanation:
Given that:
Population mean (m) = 100
Standard deviation (σ) = 21
Sample size (n) = 36
The standard error of the sampling distribution of sample mean :
Standard Error is given by:
Standard deviation / sqrt(n)
Thus,
Standard Error = 21 / sqrt(36)
Standard Error = 21 / 6
Standard Error = 3.5
