Answer:
(1, - 7 )
Step-by-step explanation:
To find a solution, choose any value for x, substitute into the equation and solve for y
Choose x = 1, then
y = - 3(1) - 4 = - 3 - 4 = - 7
Thus (1, - 7 ) is a solution to the equation
In a graph, "y" axis is the vertical axis and the blue curve is your function "f(x)". So, on the blue curve, trace and mark the place that is the highest in the given window. Notice that when "x" axis (the horizontal one) is π, the blue curve reaches its highest point,
For <span>h(x)=2cos(x)+1</span>, remember that the maximum value for <span>cos(x)</span> is "1". So, the maximum value for<span>h(x)=2(1)+1<span>=3</span></span>
The evaluate expression of
is 1/9
<h3>What is exponents and powers?</h3>
Exponent refers to the number of times a number is used in a multiplication. Power can be defined as a number being multiplied by itself a specific number of times. Exponent is the number to which a number is raised so as to define its power as a whole expression.
Given: ![3^{-2}](https://tex.z-dn.net/?f=3%5E%7B-2%7D)
Now evaluate this we have to use
= 1/x²
So,
=1/3²
=1/9
Hence, the evaluate form is 1/9.

Answer:
2.2050
Step-by-step explanation:
25% -> 2500.
25% is just a way of saying 25 out of 100. So we have to times 25 by 100 which gets you 2500. You the have to multiply 2500 by 8.82 which will get you 22050. Now the price is reduced by 25% so the answer will be less than 8. You have to add a decimal somewhere in the number 22050 and it has to be less than 8. You could but it after the second 2 but then it will be over 8. So the only spot you can put it is after the first 2 like this 2. so the answer will be 2.2050
Answer:
Because the opposite side is shorter than the hypothenuse
Step-by-step explanation:
- An acute angle is an angle which is less than ![90^{\circ}](https://tex.z-dn.net/?f=90%5E%7B%5Ccirc%7D)
- A right angle is an angle equal to ![90^{\circ}](https://tex.z-dn.net/?f=90%5E%7B%5Ccirc%7D)
- An obtuse angle is an angle which is between
and ![180^{\circ}](https://tex.z-dn.net/?f=180%5E%7B%5Ccirc%7D)
In a right triangle, we have 1 right angle and 2 acute angles.
The sine of an angle in a right triangle is defined as:
(1)
where
At the numerator we have the length of the side opposite to the angle
At the denominator we have the length of the hypothenuse
In a right triangle, the hypothenuse is the longest side of the triangle, so we have
![opp.side < hypothenuse](https://tex.z-dn.net/?f=opp.side%20%3C%20hypothenuse)
Therefore, the ratio in the eq(1) is less than 1, therefore, the sine of the angle is less than 1. Also, the sine is positive, since the ratio in the equation is a positive number.
