Answer:
98
Step-by-step explanation:
PEMDAS: Parenthesis, Exponents, Multiply, Divide, Add, Subtract, if tied, go left to right.
Elementary Algebra rhyme you should consider a requirement to remember because it's the base of a vast majority of problem's you'll encounter.
10+4(2+20)
10+4(22). . .distribute the 4 into the parenthesis aka multiply 22*4
10+88 = 98
10x6x9? Or simplify this question for me I'll figure out.
Answer:
Step-by-step explanation:
1. As x approaches zero from the right, the line representing f(x) approaches 0. As x approaches zero from the left, the line representing f(x) approaches -4 (this is the answer to the 3rd part). These two limits are different, so the limit as x approaches zero is said to be "does not exist."
2. The line representing f(x) approaches 1 as x approaches 1 from the right. The limit is 1.
3. See 1. above. The limit is -4.
Answer:
cos theta = -4/5.
sec theta = -5/4.
tan theta = 3/4.
cot theta = 4/3.
Step-by-step explanation:
sin^2 theta + cos^2 theta = 1
(-3/5)^2 + cos^2 theta = 1
cos^2 theta = 1 - 9/25
cos^2 theta = 16/25
cos theta = -4/5 (negative because it is in Quadrant 3).
sec theta = 1 / cos theta = -5/4.
tan theta = sin theta / cos theta = -3/5 / - 4/5
= -3/5 * -5/4
= 3/4.
cot theta = 1 / tan theta = 4/3.
Answer:
a. 
b. 
Step-by-step explanation:
a. The sides of an Equilateral triangle are all equal.
Then, in this case:
Based on this, you can identify that AD divides the side BC into two equal parts and the triangle into two equal Right triangles. Then:
Knowing the length CD, you can find "x" using the Pythagorean Theorem. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs.
In this case:
Substituting values and solving for "x", you get:
b. By definition, the measure of each interior angle of an Equilateral triangle is 60 degrees. Therefore:
