Which statement is true?
А. The function f(x) tan(x) is an odd function because $(-) = -f(x).
В.The function f(1) = tan(t) is an even function because its graph is symmetric about the origin.
C. The function f(t) tan(r) is an odd function because its graph is symmetric about the y-axis.
D.The function f(t) tan(x) is an even function because f(-1) =
Answers
Answer:
We conclude that the function f(x) tan(x) is an odd function because f(-x) = -f(x).
Hence, option (A) is true.
Step-by-step explanation:
We know that if function is even, then f(-x) = f(x)We know that if the function is odd, then f(-x) = -f(x)We also know that
tan x = sin x / cos xso
f(-x) = sin (-x) / cos (-x)
= -sin (x) / cos (x)
= -tan (x)
= -f(x)
Thus, tan (x) is an odd function.
Therefore, we conclude that the function f(x) tan(x) is an odd function because f(-x) = -f(x).
Hence, option (A) is true.

The required simplified value of the given expression at x = -4 and y = 4 is 16, 385/4. Option D is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
when x = -4 and y = 4.
Expression = x⁶ - x/4y
Put x = -4 and y = 4.
= (-4)⁶ - [-4 /(4×4)]
= 4096 + 1/4
= 16385/4

Answers
Answer:
x=7, angle a= 45 degrees, angle b= 65 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65
Answer:
x = 7
m∠B = 65
m∠A = 45
Step-by-step explanation:
So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.
180 - 70 = 110
Now we can set both equations equal to 110.
2 + 9x + 7x - 4 = 110
Now simplify.
2 + 9x + 7x - 4 = 110
2 + 16x - 4 = 110
16x - 2 = 110
+2 +2
------------------
16x = 112
÷16 ÷16
-----------------
x = 7
So now you can just plug 7 in for x to check your answers
2 + 9(7) = 65
7(7) - 4 = 45
65 + 45 + 70 = 180

30 * 2.8 = 84
Since all sides of the larger triangle are 2.8 times the sides of the smaller triangle, the two triangles are similar.

250x + 525y ≤ 7800
no, 15 refrigerators and 8 pianos will not fit on the truck
Step-by-step explanation:
we know that x is the refrigerators and each one is 250 lbs
this can be written as 250x
we know that y is the pianos and each one is 525 lbs
this can be written as 525y
we also know that "no more than" is the same that as less than equal to
so this can be written as ≤
we can also say that the refrigerators and pianos has to be ≤ 7800
so now we have: 250x + 525y ≤ 7800
plug in 15 to x and 8 to y
250(15) + 525(8) ≤ 7800
3750 + 4200 ≤ 7800
7950 ≤ 7800
this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck

Answers
Answer:
43%
Step-by-step explanation:
There are 39 girls. 21 of them like biology. 11 out of 34 who like chemistry are girls.
No. of girls who prefer biology = 21
There are (100-39) boys. 16 of them like physics. (34-11) of them like chemistry.
No. of boys who prefer biology = 100-39-16-34+11
= 22
Percentage of students who prefer biology = [tex]\frac{21+22}{100}[/tex] × 100%

A furniture store owner buys a sofa for $400 and marks it up %90 to sell it. During the stores anniversary sale she sells the sofa for %25 off. How much profit will the store owner make on the sofa during the anniversary sale?
Answers
Answer:
Anniversary sale price= $570
Step-by-step explanation:
Giving the following information:
Purchase cost= $400
Mar-up percentage= 90%
First, we need to calculate the "normal" selling price:
Selling price= 400*1.9= $760
Now, we can determine the anniversary sale price:
Anniversary sale price= 760 - (760*0.25)= $570
