why tan 90 is not defined
Answer:
As we have got results as infinity and we cannot define infinity and we cannot define infinity therefore tan 90 is undefined
Answer:
Its undefined because you can't divide 1 by
Nothing multiplied by 0 will give an answer of 1 , So the answer is undefined

Answer:
1 out of 336 chance
Step-by-step explanation:
Since you picked three numbers, you are going to put three blanks.
What to do in this situation is to have _ _ _. Since there are numbers 1-8, what you want to do is take the three biggest numbers and multiply them together. in this case, they would be 8-7-6. Multiply that and you get 336.
the area of right triangle is 50 m square. if one of its legs is 20cm find the lenght of the other leg?
The height of the right angles triangle having an area of 50 sq cm and a base of 20 cm is 5 cm.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
Given, The area of a right triangle is 50 m square. if one of its legs is 20cm
We know the area of a triangle is (1/2)×lenght×height.
Therefore
(1/2)×20×height = 50.
20×height = 100.
height = 100/20.
height = 10/2.
height = 5 cm.

When you round a number, what should you do with
the digits to the right of the place to which you
are rounding?
Answer:
In general, to round to a certain place value, look at the digit to the right of that place value and make a decision. Example: 5.1837 to the nearest hundredth would be 5.18 (round down since 3<5 ), but to the nearest thousandth, it is 5.184 (round up because 7≥5 ).

What is the value of 7−2ℎ, given g = 3 and h = 5?
Answer:
- 3
Step-by-step explanation:
Given
7 - 2h ( substitute h = 5 into the expression )
= 7 - 2(5)
= 7 - 10
= - 3
On evaluating the function at h = 5, we get -
f(5) = - 3.
We have a function -
f(h) = 7 - 2h
We have to find the value of f(h) at h = 5.
Evaluate - f(x) = Sin( [tex]\frac{\pi }{x}[/tex] ) at x = 2.f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )
f(2) = Sin( [tex]\frac{\pi }{2}[/tex] )
f(2) = 1
According to the question, we have -
f(h) = 7−2ℎ
Now, evaluating the function at h = 5, we get -
f(5) = 7 - 2 x 5 = -3
Hence, on evaluating the function at h = 5, we get -
f(5) = - 3.

determine the equation of the vertical line that passes through (9, -7)
Answer:
x = 9
Step-by-step explanation:
For a vertical line, slope is undefined as tan π/2 is undefined. Therefore we cannot express the equation of straight line in terms of it's slope.
For a vertical line, equation is given by, x = c where c is the point on x axis from which the given line passes.
Therefore x = 9 is the equation.

Terica correctly simplifies the radical expression [tex]\sqrt[4]{81}[/tex] by first rewriting it as a rational exponent.
Which expression shows Terica's first step?
Answer:
Step-by-step explanation:
The symbol [tex] \sqrt[n]{a}[/tex] means [tex]a^{1/n}[/tex].
So then
[tex]\sqrt[4]{81}=81^{\frac{1}{4}}[/tex].
The expression that shows Terica's first step is [tex]81^\frac{1}{4}[/tex].
What is an exponent and why we need this form ?An exponents indicates how many times a number is multiplied by it self.We need this form as it is more compact when writing large large numbers.
According to the given question Terica correctly simplifies the radical expression [tex]\sqrt[4]{81}[/tex] by first rewriting it as a rational exponent.
We know [tex]\sqrt[n]{x}[/tex] can be written in rational exponent as [tex]x^\frac{1}{n}[/tex].
∴ [tex]\sqrt[4]{81}[/tex] can be written in radical exponent as [tex]81^\frac{1}{4}[/tex] which is
= [tex](9^2)^\frac{1}{4}[/tex].
= [tex](9)^\frac{2}{4}[/tex].
= [tex](3^2)^\frac{2}{4}[/tex].
= [tex](3)^\frac{4}{4}[/tex].
= [tex]3^1[/tex].
= 3.

Answer:
13
Step-by-step explanation:
To find g f(2) , evaluate f(2) and substitute the value obtained into g(x)
f(2) = 2(2) + 1 = 4 + 1 = 5 , then
g(5) = 3(5) - 2 = 15 - 2 = 13

two angles and complementary. the measure of one angle is 21 more than twice the measure of the other angle, find the measure of the angles.
Answer:
if it is 21 more thn twice then 21*2 would equal 42 then they are complementary so the you would get 49 as the second angle
Step-by-step explanation:
Answer:
the answer would be 67 and 23.
Step-by-step explanation:
Complementary angles are angles that add up to measure 90 degrees.
lets say angle one is y.
angle two would be 2y + 21.
so, 90 = y + 2y + 21. Group like terms to get 90= 3y +21.
subtract 21 from both sides 69=3y
divided both sides by three 23=y
so angle one is 23, and if you plug in 23 for y in angle two's equation you get 67.
