Answer:
A. 3
Step-by-step explanation:
In a function, the inputs do not repeat.
The inputs are assigned to exactly one output for each.
Three is one of the options. Three is already an input in the given function.
Replacing the ? with 3 would create the non-function.
(3,5) (2, 4) (9, 0) (3,6)
Option A should be the correct answer.
Hope this helps.
Answer:
1.32
Step-by-step explanation:
Consider ...
x = sec⁻¹(4) . . . . . the inverse secant function of 4, also written arcsec(4)*
Taking the secant of both sides, we have ...
sec(x) = 4
Writing this in terms of more familiar functions, it is ...
1/cos(x) = 4
cos(x) = 1/4
Now, we can use a calculator to find the inverse function. Be sure the calculator is in the appropriate angle mode. We suspect the desired result is in radians.
x = cos⁻¹(1/4) ≈ 1.318116
sec⁻¹(4) ≈ 1.32 . . . . . radians
_____
* One way to read this is "the angle whose secant is 4." This helps remind you that the result is an angle, so can be in degrees or radians (or any of several other angle measures).
Answer:
See below.
Step-by-step explanation:
For the triangle to be a right triangle there must be a pair adjacent sides which are at right angles to each other - that is whose slope product = -1.
Slope of AB = (4-2)/(-6- -3) = -2/3.
Slope of BC = (8-4)/ (1 - - 6) = 2/7
Slope of AC = (8-2) / (1 - -3) = 6/4 = 3/2.
Now 3/2 * -2/3 = -1 so sides AB and AC are at right angles and the 3 points are the vertices of a right triangle.
Answer:
The weigh in gram is 
Step-by-step explanation:
From the question we can even write out an equation which gives us the formula
is the density in this density formula, and since and from the question we know what the mass will be and what the volume will be.
in the equation above we just need to plug in the 202 milliliter into the equation.
Then if we cross multiply we have
grams = 0.685× 202
=138.7
Therefore, the weight in grams is 138.7
3 inches is the answer... I think
