Select Correct or Incorrect for each equation. Equation Correct Incorrect

Mathematics
1 answer:
AleksandrR [38]2 years ago
7 0

Answer:

<u><em>1st equation:</em></u>

\frac{-1+1}{-1} = 0\\

Simplify the numerator

-1 + 1 = 0

\frac{0}{-1} = 0

(zero divided by any number (other than zero) is zero)

1st equation is correct

<u><em>2nd equation:</em></u>

\frac{-1}{1} = -1

This is because a negative number divided by a positive number is a negative number.

So, \frac{-1}{1} = 0 is incorrect.

2nd equation is incorrect

x = 44°

Step-by-step explanation:

Since AB is a diameter,

arcAC + arcCB = 180

92° + arcCB = 180

or

arcCB = 88°

ArcCB is the intercepted arc and by definition, the inscribed angle x is half the measure of the intercepted arc. Therefore,

x = (1/2)arcCB

= 44°

Sketch the curve y = \sqrt{x+3} .
Ierofanga [76]

The area bounded by the curve, x-axis and y-axis of the function y = √(x + 3) is 2√3

<h3>How to determine the area bounded by the curve, x-axis and y-axis?</h3>

The curve is given as:

y = √(x + 3)

The area bounded by the curve, x-axis and y-axis is when x = 0 and y = 0

When y = 0, we have:

0 = √(x + 3)

This gives

x = -3

So, we set up the following integral

A = ∫ f(x) d(x) (Interval a to b)

This gives

A = ∫ √(x + 3) d(x) (Interval -3 to 0)

When the above is integrated, we have:

A = 1/3 * [2(x + 3)^(3/2)] (Interval -3 to 0)

Expand

A = 1/3 * [2(0 + 3)^3/2 - 2(-3 + 3)^3/2]

This gives

A = 1/3 * 2(3)^3/2

Apply the law of indices

A = 2(3)^1/2

Rewrite as:

A = 2√3 or 3.46

Hence, the area bounded by the curve, x-axis and y-axis of the function y = √(x + 3) is 2√3

HELP PLEASE!!!!! 50 POINTS!!!!!!!!
ryzh [129]

Answer:

see below

Step-by-step explanation:

f(x)= -0.08x(x^2-11x+18)

Factor

f(x)= -0.08x(x-9)(x-2)

Using the zero product property to find the zeros

0= -0.08x(x-2)(x-9)

-0.8x =0    x-2 =0  x-9 =0

x=0            x=2           x=9

Multiply out

f(x) =  -0.08 x^3 + 0.88 x^2 - 1.44 x

The highest power is x^3

f(-∞) = -0.08( -∞)^3 = - ( -∞) = ∞

As x goes to -∞  f(x) goes to +∞

f(∞) = -0.08( ∞)^3 = - ( ∞) = -∞

As x goes to ∞  f(x) goes to -∞
