Answer:
Answer in explanation
Step-by-step explanation:
The graph of f does not cross the x-axis. We know this because for any value x, we always get that x^2+4 is positive. x^2 is positive or zero ( 0 or greater than 0) for any x but adding 4 to it makes It 4 or greater than 4.
The discriminant is negative.
That is, b^2-4ac is negative.
Upon comparing ax^2+bx+c to x^2+4 we see that a=1, b=0, and c=4..
Plugging those into b^2-4ac gives
(0)^2-4(1)(4)
=0-16
=-16.
Negative discriminant implies two nonreal zeros so it will not cross the x-axis.
(Positive discriminant implies 2 real and zero discriminant imples 1 real.)
What is the MODE of the data - (12, 8, 6, 12, 16, 12) *
help plsssss
Answer: Mode = 12
Explanation: The mode is the most frequent value, so it is the value that shows up the most. In this case, that would be the value "12" since it shows up three times (while the other values only show up once).
Answer:
12
Step-by-step explanation:
For future reference mode means MOST. So in this data, number 12 is repeated the most. That would mean the MODE is 12.
Good Luck!!!

____<9 ____ >6 which whole numbers will make both statements true
Answer:
8 and 8
Step-by-step explanation:
8 is less than 9
8 is more than 6
8 and 8, is the whole numbers will make both statements true.
i.e. 8<9 & 8>6.
What is number?A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.
here, we have,
to find the whole number which will make both statements true,
so, we get,
8 is less than 9
and,
8 is more than 6
Hence, i.e. 8<9 & 8>6.

solve for x
4(x+7)+98x+45+7y=567
Subtract 73 from both sides of the equation.
102x+7y=567-73
Subtract 7y from both sides of the equation.
102x=567-73-7y
Subtract 73 from 567
102x=494-7y
Divide each term by 102 and simplify
Divide each term 102x=494-7y by 102
[tex]\frac{102x}{102} =\frac{494}{102} +\frac{-7y}{102}[/tex]
Cancel the greatest common factor which is 102x/102
[tex]\frac{102x}{102} =\frac{494}{102} +\frac{-7y}{102}[/tex]
Divide x by 1[tex]x\frac{492}{102} +\frac{-7y}{102}[/tex]
Cancel the common factor is 494 and 102
Factor 2 out of 494
[tex]x\frac{2(247)}{102} +\frac{-7y}{102}[/tex]
Factor 2 out of 102
[tex]\frac{2*247}{2*51} +\frac{-7y}{102}[/tex]
Cancel the common factor which is 2
Rewrite the expression.[tex]x=\frac{247}{51} +\frac{-7y}{102}[/tex]
Move the negative in front of the fraction

Answer:
90 - 43 = x
Step-by-step explanation:
Answer: 47
Step-by-step explanation:
Dude just subtract 43 from 90, since you are given a 90 degree angle.
But if you need the equation: 43+x-7=90
add 43 and (-7) which gives us 36
new equation is now: 36+x=90
move the 36 to the other side
x=54
now plug it in x(54)-7=47
which of the following is equivalent to the expression below when x >0?

C

Ten points! Teresa's family is thinking about buying a family pass to a gym. The pass is $120 for a family of 6. Individual passes are $25 each. How much money can Teresa's family save by purchasing a family pass instead of 6 individual passes?
Answer: If Teresa‘s family bought individual passes it would be $150 so then if you subtract it would be $30. Teres’s family saved 30 dollars.
Step-by-step explanation:
They can save $30
Step-by-step explanation:
If the family pass is $120 and individual passes are $25 dollars.
6 people times $25 dollars = $150
Family pass: $125
$150-$125=$30

Answer:
<B = 95degrees
<D = 137 degrees
Step-by-step explanation:
From the given diagram, the sum of the adjacent sides of the trapezoid is 180degrees. Hence;
<A +<B = 180
85 + <B = 180
<B = 180 - 85
<B = 95degrees
Similarly
<C + <D =180
43 + <D = 180
<D = 180 - 43
<D = 137 degrees

Blake collects stamps. He collected a total of 175 stamps. If 72% of the stamps he collected were
foreign, how many other stamps did he collect?
Blake collected stamps that were not foreign.
(Type a whole number.)
Answer: 49
Step-by-step explanation:
If 72% of the stamps he collected were
foreign, the percentage of the other stamps will be: = (100% - 72%) = 28%
Since the total number of stamps collected are 175, the number of other stamps collected will be:
= 28% of 175
= 28% × 175
= 28/100 × 175
= 0.28 × 175
= 49
Therefore, he collected 49 other stamps that were not foreign

answers are
60m cubed
360m cubed
1130m cubed
2260m cubed
Answer:
≈ 1130 m³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
Here r = 6 and h = 10 , then
V = π × 6² × 10 = π × 36 × 10 = 360π ≈ 1130 m³
Write an equation of the line below
Answer:
y = 4/5x - 2
Step-by-step explanation:
To create an equation with just a line compare two points on the graph and see how far the x and y points are on the graph then put them into a fraction with y over x then find the y intercept or find where the x coordinate equals 0 in this case it was (0, -2). Now put it all together:
y = mx + b
mx = comparison of two points
b = y intercept

In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
Hello, I Am BrotherEye
Answer:
27.92 units
Step-by-step explanation:
Radius (qr) = r = 16 units
<QŘS = θ = 82°
Length of an arc = (Θ / 360) * 2πr
L = (θ / 360) *2πr
L = (82 / 360) * 2π * 16
L = 0.2777 * 100.53
L = 27.917 units
L = 27.92 unit

Solve PLZ The width of a rectangle is 33 inches and the area is at least 165 inches. Which inequality could be used to find the minimum length?
Answer:
A
Step-by-step explanation:
at least are key words for [tex]\geq[/tex] symbol
Area is L x W and since you have W its basically:
[tex]33x\geq 165[/tex]
How do I get the answer to question #5?
Answer:
7 cm
Step-by-step explanation:
Area of a parallelogram formula:
[tex]A=bh[/tex] where b is the base length and h is the height
Plug in known values (A=112, b=16 and h=x)
[tex]112=16x[/tex]
Divide both sides by 16 to isolate x
[tex]\frac{112}{16} = \frac{16x}{16}\\7=x[/tex]
Therefore, x is equal to 7 cm.
I hope this helps!
Trigonometry, can anybody help??
Answer:
angle B: 39
AC: 7.288
AB: 11.58
(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)
Step-by-step explanation:
To solve this we will use SOH, CAH, TOA
we have the angle and the one opposite to it which means we can use either SOH or TOA
let's use TOA
tan(51)=(9/x)
x= 7.288
We can now use pahtagaryous theroem to solve for the hyptonouse
we have
9²+7.288²=C²
C=11.58
Finally, to find angle B we will recall that the angles of a triangle must add to 180.
51+90+a=180
a=39
i need help on this one too
Answer:
V = 235.5
or V = 18π
Step-by-step explanation:
V=πr^2h
Volume of a cylinder is (pi)(radius)(radius)(height)
V = (3.14)(3)(3)(2)
V = 56.52
Or, since it said you can leave it as pi,
V = 18π

Answer:
The area is: 4x^5 + 8x^3
Equation: (2x^3 + 4x) * 2x^2
^ = exponent
* = multiply
Step-by-step explanation:
When you try to find the rectangle of an area, the formula is:
Length * Width
In this case, the length is:
2x^3 + 4x
And the width is:
2x^2
Now let's solve the equation.
(2x^3 + 4x) * 2x^2
We need to combine like terms
2x^3 + 2x^2 = 4x^5
After evaluating the equation:
4x^5 + 8x^3
The area is: 4x^5 + 8x^3
hope this helped :)
