Answer: (3x+13)°= 118° and (x-8)°= 27°.

Step-by-step explanation:

We know that , According to the angle sum property of triangle : the sum of all angles of a triangle is 180°.

According to the given picture , in triangle ABC , we have

∠A =(3x+13)° , ∠B = (x-8)° and ∠C=x°

Now , by angle sum property , we have

(3x+13)° + (x-8)° +x°= 180°

⇒ 3x+13+x-8+x=180

⇒ 5x+5=180

⇒ 5x=175 [subtracting both sides by 5]

⇒ x= 35 [Dividing both sides by 5]

Now , (3x+13)° =( 3(35)+13) ° =118°

(x-8)°= (35-8)° = 27°

Hence, the answer is (3x+13)°= 118° and (x-8)°= 27°.

Answer: The answer should be that the velocity and acceleration decreases ! :)

Step-by-step explanation: With velocity, the pure definitions are "quickness of motion," and "rapidity of movement." So with this, when you think about it, the speed/velocity of the baseball decreases the higher it goes because of gravity slowly getting stronger the higher up it goes. So the answer would be that the velocity and the acceleration decreases. (hope I helped :') )

A puzzle contains a triangular piece with a base of 3 in. and a height of 4 in. A manufacturer wants to make 80 puzzles. Find th

kari74 [83]

Since the base is 3 inches and the height is 4 inches, as well as the area of a triangle being base*height/2, we get 3*4/2=6 in. for each triangle. Since we need 20 pieces for each puzzle, we multiply 6 by 20 to get 120. In addition, since 80 puzzles are needed, with 20 pieces for each puzzle, we have 120 inches for each puzzle and 120*80 = 9600 square inches of wood used

What is the total surface area of this square pyramid?

slamgirl [31]

Answer:

The total surface area of this square pyramid is $297\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to

$SA=b^{2} +4[\frac{1}{2}(b)(h)]$

we have

$b=9\ mm$ ----> the length side of the square base

$h=12\ mm$ ----> the height of the triangular faces

substitute the values

$SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}$

What is the derivative of y with respect to x if y = 2/X4

zepelin [54]

You're correct, the answer is C.

Given any function of the form $y=x^n$ , then the derivative of y with respect to x ( $\frac{dy}{dx}$ ) is written as:
$\frac{dy}{dx}=nx^n^-^1$

In which $n$ is any constant, this is called the power rule for differentiation.

For this example we have $y= \frac{2}{x^4}$ , first lets get rid of the quotient and write the expression in the form $y=x^n$ :
$y= \frac{2}{x^4} =2x^-^4$

Now we can directly apply the rule stated at the beginning (in which $n=-4$ ):
$\frac{dy}{dx}=(2)(-4)x^{-4-1}=-8 x^{-5}= -\frac{8}{x^5}$

Note that whenever we differentiate a function, we simply "ignore" the constants (we take them out of the derivative).
