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

The graph of the the function f(x) is given below.
MrRissso [65]

Answer:

  • dne
  • 1
  • -4

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.

given sin theta = -3/5 and csc theta -5/3 in quadrant 3, find the value of other trigonometric functions using a Pythagorean Ide
tiny-mole [99]

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.

A. What is the value of x?<br> b. What is the measure of<br> angle B?
Papessa [141]

Answer:

a. x=4\sqrt{3}

b.  m\angle B =60\°

Step-by-step explanation:

a. The sides of an Equilateral triangle are all equal.

Then, in this case:

AB=BC=CA=8

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:

CD=BD=\frac{8}{2}=4

Knowing the length CD, you can find "x" using the Pythagorean Theorem. This is:

a^2=b^2+c^2

Where "a" is the hypotenuse and "b" and "c" are the legs.

In this case:

a=8\\b=x\\c=4

Substituting values and solving for "x", you get:

8^2=x^2+4^2\\\\\sqrt{8^2-4^2}=x\\\\x=4\sqrt{3}

b. By definition, the measure of each interior angle of an Equilateral triangle is 60 degrees. Therefore:

 m\angle B =60\°
