The value of f(0) is -1
<h3>What is a function?</h3>
A function can be defined as an expression, law or rule that explains the relationship between two variables; a dependent and an independent variable.
Given the function;
f(x)= -x - 1
To determine f(0), we substitute the value of x as 0 in the function
So, we have;
f(0) = -(0) - 1
f(0) = -0 - 1
f(0) = -1
Thus, the value of f(0) is -1

a quantity of carbon - 14 will take 1342.5 years to become 1/8 of its original size.
Step-by-step explanation:
1/2 of the atoms decayed after 5370 years
now half of( 1/2 of )the atoms decayed after 5370/ 2 years
i.e, 1/4 of the atoms decayed after 2685 years.
again half of (1/4 of the atoms ) decayed after 2685/2 years
i.e, 1/8 of the atoms decayed after 1342.5 y<u>ears.</u>
Answer:
-1
Step-by-step explanation:
I'm. it 100% sure because the equation has A's as variable but other than that the answer should be -1 hope this helps -2x-5x=7 so you would subtract 5 from 2 and get -7x then divide so -7/7=-1
Answer: 23.09 m
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation that the dog is looking up, the opposite side (x) is the height of the tree house, and the adjacent side is the distance between the dog and the tree house base.
Replacing with the values given:
Tan 30 = x/ 40
Solving for x
tan30 (40) =x
x= 23.09 m

First organize the information we are given according to the problem.
*Angle 1 and Angle 3 are congruent.
*Angle 4 and Angle 6 are congruent.
*Angle 3 and Angle 4 are complementary. This means that the measure of angle 3 plus the measure of angle 4 equals to 90.
Now knowing this:
Angle 3 is 26.5° because it is congruent to angle 1.
Angle 4 is 63.5° because by subtracting 26.5 from 90, you'll get the sum of 63.5. Once more, this is because angles 3 and 4 are complementary.
Angles 4, 5, and 6 are adjacent angles which form a straight line. Straight lines have an angle measure of 180°. So together, both angles 4 and 6 measure 127°. Knowing that a line is 180°, the measure of angle 5 needs to be 53°. You can check this once more by adding all the three numbers and getting 180°.
