Answer:
The answer I’m pretty sure is C
Step-by-step explanation:
U find the slope for each segment. For example, find the slope for BC. Find the points of B and C. B- (5,6) and C-(6,2). Using the formula of finding the slope, it’s gonna be 6-2/5-6, and as you can see, option A‘s BC is not the same as the one we have, therefore it cannot be Option A. Do the rest the same way.
If a radius of a sphere is divided by 2, will the surface area be divided by 2?
can some1 help me plss
Answer:
c is the answer!
Step-by-step explanation:
You have to first do the problem. If the tax is 2 and the total is 42, you would do 42 - 2. Then you have to divide it into 5. (the amount of items) You will get 8. Now you have to find what question is wrong. So if you would compare the way of figuring it out to the answers you would see that 5 is not how much each product cost. So c is the answer!
If you have any questions ask me please! :)

A fair, 6-sided die is rolled 45 times. Predict how many times it will land on a number greater than 4.
one third
4
10
15
Answer: 15
Step-by-step explanation:
1/3 times 45 is 15
We can predict that the die will land on a number greater than 4 approximately 15 times out of 45 rolls.
What is probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Since we are interested in the number of times the die lands on a number greater than 4, we can add the probabilities of rolling a 5 or a 6.
Therefore, the probability of rolling a number greater than 4 on one roll is:
P(5 or 6)
= P(5) + P(6)
= 1/6 + 1/6
= 1/3
To predict how many times the die will land on a number greater than 4 out of 45 rolls, we can multiply the probability of rolling a number greater than 4 on one roll by the number of rolls:
= 45 x (1/3)
= 15
Therefore, we can predict that the die will land on a number greater than 4 approximately 15 times out of 45 rolls.

A cone has a height of 4 in and a radius of 6 in. What is the volume of the cone?
8π in3
24π in3
48π in3
144π in3
Answer:
48π in³
Step-by-step explanation:
\(V=\frac{1}{3} \pi r^2h\)
Plug in the radius 6 in and the height 4 in
\(V=\frac{1}{3} \pi (6)^2(4)\\V=\frac{1}{3} \pi (36)(4)\\V=\frac{1}{3} \pi (144)\\V=48\pi\)
Therefore, the volume of the cone is 48π in³.

Find all possible values of a such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1.
Answer:
\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0\)
Step-by-step explanation:
Given quadratic equation:
\(ax^2 + (2a + 2)x + a + 3 = 0\)
To find the possible values of "a" such that the given equation has two roots and the distance between them on the number line is greater than 1, use the quadratic formula.
\(\boxed{\begin{minipage}{4 cm}\underline{Quadratic Formula}\\\\$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$\\\\when $ax^2+bx+c=0$ \\\end{minipage}}\)
Comparing the coefficients:
\(a = a\)\(b = (2a + 2)\)\(c = (a + 3)\)Substitute the coefficients into the quadratic formula:
\(x=\dfrac{-(2a+2) \pm \sqrt{(2a+2)^2-4a(a + 3)}}{2a}\)
Simplify the discriminant (the part under the square root sign):
\(x=\dfrac{-(2a+2) \pm \sqrt{-4a+4}}{2a}\)
Factor out 4 from the discriminant:
\(x=\dfrac{-(2a+2) \pm \sqrt{4(-a+1)}}{2a}\)
\(\textsf{Apply the radical rule:} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}\)
\(x=\dfrac{-(2a+2) \pm \sqrt{4}\sqrt{-a+1}}{2a}\)
Therefore:
\(x=\dfrac{-(2a+2) \pm 2\sqrt{-a+1}}{2a}\)
Factor out the common term 2:
\(x=\dfrac{-(a+1)\pm \sqrt{-a+1}}{a}\)
Therefore, the two solutions are:
\(x=\dfrac{-a-1+\sqrt{-a+1}}{a},\;\;x=-\dfrac{a+1+\sqrt{-a+1}}{a}\)
As both solutions have "a" as their denominator, a ≠ 0.
Note: When substituting a = 0 into the original equation, we are left with a linear equation, which only has one root. Therefore, this confirms that a ≠ 0.
Now we have found expressions for the two roots, we can set the distance between them to greater than 1:
\(\dfrac{-a-1+\sqrt{-a+1}}{a}-\left(-\dfrac{a+1+\sqrt{-a+1}}{a}\right) > \:1\)
\(\dfrac{-a-1+\sqrt{-a+1}}{a}+\dfrac{a+1+\sqrt{-a+1}}{a} > \:1\)
Simplify:
\(\begin{aligned}\dfrac{-a-1+\sqrt{-a+1}+a+1+\sqrt{-a+1}}{a}& > 1\\\\\dfrac{2\sqrt{-a+1}}{a}& > 1\\\\2\sqrt{-a+1}& > a\\\\(2\sqrt{-a+1})^2& > a^2\\\\4(-a+1)& > a^2\\\\-4a+4& > a^2\\\\a^2+4a-4& < 0\\\\(a+2)^2-8& < 0\\\\(a+2)^2& < 8\end{aligned}\)
\(\textsf{For\;\;$u^n < a$,\;\;if\;$n$\;is\;even\;then\;\;$-\sqrt[n]{a} < u < \sqrt[n]{a}|$:}\)
\(-\sqrt{8} < a+2 < \sqrt{8}\)
Therefore:
\(-\sqrt{8} -2 < a < \sqrt{8}-2\)
\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2\)
So the possible values of "a" such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1 are:
\(\large{\boxed{-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0}\)

A train leaves the station at time t=0. Traveling at a constant speed, the train travels 420 kilometers in 3 hours. Answer parts a and b.
Answer:
f(t) = 160t,
d = f(t)
The function that relates the distance traveled d to the time t is:
f(t) = 160t, where d = f(t)
Step-by-step explanation:
If the train travels 480 kilometers in 3 hours, then it will travel 160 kilometers in one hour:
d = 160t
Now we replace d by f(t) because d = f(t):
f(t) = 160t
for any given value of t, d will be equal to t multiplied 160 times

A bat is sitting in a tree. He leaves the tree and flies up to a speed of 4 meters per second in 8 seconds. How far does he travel?
Answer:
32 meters
Step-by-step explanation:
4*8=32 and you have to do this because he flies 4 meters per second and in 8 seconds
With the given speed and time a bat travelled 32 meters.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Given that, A bat is sitting in a tree. He leaves the tree and flies up to a speed of 4 meters per second in 8 seconds.
We know that, speed = Distance/Time
Now, 4 = Distance/8
Distance = 32 meters
Therefore, a bat travelled 32 meters.

Answer:
Whichever athlete the team manager chooses does not matter
Step-by-step explanation:
Athlete A Average = 14.4
Athlete B average = 14.4
Both athletes have the same average so it would not matter who is chosen for the 100m race
Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers. If necessary, use / for the fraction bar(s).
Answer:
For the top: Angles E,F,B and D are all Supplementary to angle M.
Each of them has a measure of 135°
For the bottom, angles J,H,P and R are all Supplementary to angle M. They all have measures of 105°
Step-by-step explanation:
The directions say "identify an angle" so you can select any one of the angles listed.
Supplementary angles add to 180° so to find the measure, Subtract the given measure from 180.
180-45=135 180-75=105

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500
