Evaluate step by step
g(-2)=x^2+3X+2
And
g(3.14)=x^2+3X+2
Answer:
g(-2) = 0
g(3.14) = 21.2796
Step-by-step explanation:
Simply substitute the values for x.
Step 1: Find g(-2)
g(-2) = (-2)² + 3(-2) + 2
g(-2) = 4 - 6 + 2
g(-2) = -2 + 2
g(-2) = 0
Step 2: Find g(3.14)
g(3.14) = (3.14)² + 3(3.14) + 2
g(3.14) = 9.8596 + 9.42 + 2
g(3.14) = 19.2796 + 2
g(3.14) = 21.2796

Sort the following objects by length. Place the shortest object at the top.
Answer:
Ok, here we have two points A and B.
The shorter object will be the second option, AB with a line on top, this is a segment, so the length of this object is equal to the distance between A and B.
The next one is AB with an arrow pointing to the right, this is ray, is a line that starts in A and passes through B, and continues infinitely.
The third will be the bottom option, AB with a double-arrow on top, this is the notation for a line that passes through A and B, and it extends to infinity in both directions.

Answer:
Lily has a higher ratio than Logan
Step-by-step explanation:
The True statement is Lily has a higher ratio than Logan
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

simplify the expresssion 2x^2+8+3x^2+4x-10
Answer:
x= 0.348 OR X= -1.148
Step-by-step explanation:
Given that:
2x^2+8+3x^2+4x-10
The first step is to rearrange the parameters given, by doing so, we have:
= 2x^2 +3x^2 +4x -10+8
= 5x^2 +4x - 2
The above equation forms the basis of a quadratic equation;
So using quadratic formula
= (-b +/- (√b^2-4ac))/2a
= (-4 +/- (√4^2 -4*5*(-2))/2*5
= -4 +/- (√ 16 - (-40))/10
=( -4 +/- √ 56 ) / 10
=( -4 +√ 56 ) / 10 OR =( -4 - √ 56 ) / 10
= (-4 + 7.48)/10 OR (-4 -7.48)/10
= 3.48/10 OR -11.48/10
= 0.348 OR. -1.148
SO, x= 0.348 OR X= -1.148
if a circle's circumference is 15 inches what is its radious? leave the symbol pi in your answer
Answer:
the radius is 2.38
Step-by-step explanation:
use the formula c=2pi r
Answer:
15/2π
Step-by-step explanation:
If the circumference is 15 inches, we can create an equation using the following formula:
Circumference of circle = 2 x π x radius
which is C = 2πr
Now, substituting our value of the circumference (15) into the equation, we get:
15 = 2πr
In order to find r, the radius, we must divide both sides by 2π, which makes r the subject. This cancels out the 2π on the right side, leaving us with:
15/2π = r
So the radius is 15/2π.
A rock is thrown upward with a velocity of
22 meters per second from the top of a
45 meter high cliff, and it misses the cliff on the way back down. When will the rock be
9 meters from ground level? Round your answer to two decimal places.
Answer:
5.76 seconds
Step-by-step explanation:
We are given;
Position of rock from ground level; h(t) = 9 m
Height of cliff;h_0 = 45 m
Velocity;v_0 = 22 m/s
To solve for the time, we will use the gravity formula which is;
h(t) = (-1/2)gt² + (v_0)t + h_0
Plugging in the relevant values to get;
9 = (-1/2)(9.81)t² + 22t + 45
Subtract 9 from both sides to get;
-4.905t² + 22t + 45 - 9 = 0
-4.905t² + 22t + 36 = 0
Finding the roots of the equation through quadratic formula gives;
t = 5.76 or -1.27
t cannot be negative, so we will use the positive value to get;
t = 5.76 s
Thus, the rock will be 9m from the ground level after 5.76 seconds
Michael has a substantial student debt, but he recently got a new job, which came with a signing bonus. He calculates that with his new job, he can put aside a fixed amount of money every month to pay off his debt. He also puts the entirety of his bonus towards paying off his debt. He constructs the expression 36,700-(5,000+500m) to represent the size of his debt after m months. Which number describes the value of his signing bonus?
Answer:
5000
Step-by-step explanation:
Given the following :
Constructed expression used to express size of debt after m, months :
36,700 - (5000 + 500m)
Since it was stated that he his whole signing bonus was dedicated towards paying his debt, then this will be a constant figure or digit.
Then a fixed amount from his monthly pay is also dedicated towards offsetting the loan:
Thus the fixed amount will be the Coefficient of m, where m is the number of months.
Thus total amount paid after m months can be deduced from the expression to be :
(5000 + 500m); where
5000 constant fee is the signing bonus.
Answer:
5000

Solve for x in the equation x2 + 2x + 1 = 17.
O x=-11 15
O x=-14 17
O x=-2+2V5
O x=-1:13
Answer:
x = sqrt(17) - 1 or x = -1 - sqrt(17)
Step-by-step explanation:
Solve for x:
x^2 + 2 x + 1 = 17
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x + 1)^2 = 17
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x + 1 = sqrt(17) or x + 1 = -sqrt(17)
Hint: | Look at the first equation: Solve for x.
Subtract 1 from both sides:
x = sqrt(17) - 1 or x + 1 = -sqrt(17)
Hint: | Look at the second equation: Solve for x.
Subtract 1 from both sides:
Answer: x = sqrt(17) - 1 or x = -1 - sqrt(17)

A line passes through the point , 9,−2 and has a slope of 4/3. Write an equation in point-slope form for this line.
Answer:
y + 2 = [tex]\frac{4}{3}[/tex] (x - 9)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{4}{3}[/tex] and (a, b) = (9, - 2) , thus
y - (- 2) = [tex]\frac{4}{3}[/tex] (x - 9) , that is
y + 2 = [tex]\frac{4}{3}[/tex] (x - 9)
Answer:
y+2 = 4/3( x-9)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point on the line
y - -2 = 4/3( x-9)
y+2 = 4/3( x-9)

A square rug has an area 94 ft. Write the side length as a square root. Then decide if the side length is a rational number.
Hey there! I'm happy to help!
All of the sides of a square are the same. Therefore, to find the area, you multiply the side by itself. Multiplying a number by itself is conveniently called squaring.
Doing this backwards is called finding the square root. If you have an area of 64, you square root it, showing you that the sides are 8.
Therefore, the side length here is √94.
If we put √94 into the calculator, we see that it is 9.895359715.....
That number never ends and it goes on in no particular order, so it cannot be written as a fraction of two integers and therefore is not a rational number.
