Answer:
14
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² + 1 - (1 - x)
= 3x² + 1 - 1 + x
= 3x² + x
Then
(f- g)(- 2)
= 3(- 2)² + 2
= 3(4) + 2
= 12 + 2
= 14
Which of the follwing are true statements about a 30-60-90 triangle?
Answer:
A and E
Step-by-step explanation:
The ratio of the hypotenuse to the shorter leg to the longer leg is 2:1: root 3
Answer:
A. and E.
Step-by-step explanation:
The length of the hypotenuse is always double the length of the shortest leg and you can find the long leg by multiplying the short by the square of 3.
Use a number line to help you find the sum of -24+8
Answer:
-16
Step-by-step explanation:
When adding a negative and a positive number, you need to keep in mind that your are essentially adding.
so if I have a number line
-24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14,,,,
you will start at -24 and will go up the number line (to the right) 8 times and that should get you your answer.

Drag the tiles to the correct boxes to complete the pairs.
The function (x) is represented by this table of values
Answer:
Step-by-step explanation:
Average rate of change of a function between interval x = a and x = b is given by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Average rate of change of the function in the interval [-4, -2]
= [tex]\frac{f(-2)-f(-4)}{-2-(-4)}[/tex]
= [tex]\frac{0-(-12)}{-2+4}[/tex]
= 6
Average rate of change in the interval [-2, 1]
= [tex]\frac{f(1)-f(-2)}{1-(-2)}[/tex]
= [tex]\frac{3-0}{1-(-2)}[/tex]
= 1
Average rate of change in the interval [-3, 1]
= [tex]\frac{f(1)-f(-3)}{1-(-3)}[/tex]
= [tex]\frac{3-(-5)}{1+3}[/tex]
= 2
Average rate of change in the interval [-4, 0]
= [tex]\frac{f(0)-f(-4)}{0-(-4)}[/tex]
= [tex]\frac{4-(-12)}{0-(-4)}[/tex]
= 4

which expression is equivalent to 5^10 x 5^5
Answer:
[tex] {5}^{10 + 5} = {5}^{15} [/tex]
Answer:
5^15
Step-by-step explanation:
when multiplying expressions with the same base you keep the base (the base is 5 ) and add the exponents (10 and 5) then you would get your awnser
A coordinate plane with 2 lines. The first line is labeled y equals f(x) and passes through (negative 1, 2), (0, 2), and (2, 2). The second line is labeled y equals g(x) and passes through (negative 0.5, negative 2), points at (0, negative 1), and (1, 1). The lines intersect at (1.5, 2).
Use the graph to determine the input value for which f(x) = g(x) is true.
Answer:
x=2/3
Step-by-step explanation:
Most of that information is unnecessary. Just plug in the values of f(x) and g(x) into the equation where they are equal to each other and solve.
-3x+4=2
-3x=-2
3x=2
x=2/3

A meat pie contains chicken and turkey in the ratio 4: 1. The pie contains 200g of chicken.
How much turkey is in the pie?
How much turkey is in the pie?
The mass of the turkey in the pie is 1/4 of the weight of the chicken
200/4 = 50 grams
8. At a winery 15 people are hired to pick grapes. They pick 15 tons of grapes, which yield 1200 to 1300 gallons of wine ( 1 ton = 2000 pounds). What is the yield percent for grapes to produce wine? ( Use 1250 gallons in calculations)
Answer:
290.4 %
Step-by-step explanation:
Since 15 tons of grapes are picked and 1 ton = 2000 pounds, then 15 tons = 15 × 1 ton = 15 × 2000 lb = 30000 lb which is the mass of the grapes.
Since 1200 to 1300 gallons of wine are produced and we are to use 1250 gallons in calculations, since the density of wine, ρ = 8.262 lb/gallon, and ρ = mass of wine, m'/volume of wine, v = m/v
ρ = m/v
So, making m subject of the formula, we have
m = ρv
substituting the values of the variables into the equation, we have
m = 8.262 lb/gal × 1250 gal = 10327.5 lb
So, the yield percent for grapes to produce wine = mass of grapes/mass of wine × 100 %
= 30000 lb/10327.5 lb × 100 %
= 2.904 × 100 %
= 290.4 %
So, the yield percent for grapes to produce wine is 290.4 %
A school bus can hold a maximum of 45 students. The correct inequality for this word problem is b ≤ 45. Why did I use ≤ not < in this problem?
Answer:
This sign ≤ means greater than or equal to
but, this sign < means the number which is in the side is only greater
That why the sign ≤ is used
My this answer might be wrong , because in b ≤ 45 , I am confused from where the letter " b " came from .
A bag contains red and blue marbles, such that the probability of drawing a blue marble is 37.5%
An experiment consists of drawing a marble, replacing it, and drawing another marble. The two draws are independent.
What is the probability that both of the marbles drawn are blue?
a.
24%
c.
14%
b.
39%
d.
0
I don’t know the answer
Answer:
c = 10.5
Step-by-step explanation:
Formula: the product of the lengths of the segments of one chord equal the product of the segments of the other.
a •d = c • b
7*12 = c*8
84 =8c
Divide by 8
84/8 = 8c/8
10.5 = c

3x-6y=24 y=Mx+b form
Answer:
Hi, there your answer is[tex]y=\frac{1}{2} x-4[/tex]
Step-by-step explanation:
Let's solve for y.
3x−6y=24
Step 1: Add -3x to both sides.
3x−6y+−3x=24+−3x
−6y=−3x+24
Step 2: Divide both sides by -6.
−6y /−6 = −3x+24 /−6
y=1/2x-4

Which of these does NOT describe an equivalent ratio or rate? A) 10:35 and 8:28 B) 4:10 and 10:25 C) 40km/h and 0.06 km/min D) 1.5L for $2.30 and 7.5 L for $11.50
Answer:
C
Step-by-step explanation:
convert option a to the lowest term
10 : 35 = 2: 7 (divide both ratios by 5)
8 : 28 = 2 : 7 (divide both ratios by 7)
convert option b to the lowest term
4 : 10 = 2 : 5 (divide both ratios by 2)
10 : 25 = 2 : 5 (divide both ratios by 5)
option c
divide 40km/h by 60 to convert to km / min
40/60 = 0.7 not equivalent

Determine the value of each variable below. Round to the nearest tenth.
Answer:
Step-by-step explanation:
1) tan = opposite / adjacent
tan * adjacent = opposite
adjacent = opposite/tan
adjiacent = 60/1,600335 = 37.5
2) the two leg are congruent so the two angles are congruent
the sum of the inner angles of a triangle is 180 degrees
so
a = 45 degrees
b = 45 degrees
3) cos = adjacent/hypotenuse
adjacent = cos * hypotenuse
adjacent = 0,920505 * 45
adjacent = 41.4
