3x² + 7x + 6
Step-by-step explanation:
Big Rectangle:
A = bh
A = (x + 3)(x + 2)
A = x² + 2x + 3x + 6
A = x² + 5x + 6
Small rectangle:
A = bh

The diameter of a sphere is multiplied by 1/5. What is the effect on the surface area?
Answer choices:
5 times bigger
5 times smaller
25 times bigger
25 times smaller
15 times bigger
15 times smaller
125 times bigger
125 times smaller
Answer is not here
Answer:
25 times smallerStep-by-step explanation:
Scale factor is:
k = 1/5Ratio of surface areas is:
k² = (1/5)² = 1/25Surface area will be 25 times smaller
Correct choice is D
We know the ratio of sides to area
a/b=a²/b²So
If diameter is multiplied by 1/5
Surface are increases
(1/5)²1/2525 times smaller

Answer:
linear
Step-by-step explanation:
We notice that adjacent x-values all differ by 1.
Similarly, we notice that all y-values differ by 0.5. When differences are constant, the function is linear.
Can anybody help and explain this? (Part a and b)
Answer:
Step-by-step explanation:
Part A
Given equation of the circle is,
x² + y² - 4x + 2y = b
Standard equation of the circle is given by,
(x - h)² + (y - k)² = r²
Here, (h, k) is the center and r = radius of the circle
Now we will convert this equation into a standard equation of the circle,
x² - 4x + y² + 2y = b
x² - 2(2x) + 2² + y² + 2y + 1² = b + 2² + 1²
(x² - 2(2x) + 4) + (y² + 2y + 1) = b + 4 + 1
(x - 2)² + (y + 1)² = √(b + 5)²
Therefore, (2, -1) will be the center of the given circle.
y-coordinate of the circle = -1
Part B
Since, radius of the circle is 7 units,
Therefore, [tex]\sqrt{b+5}=7[/tex]
b + 5 = 49
b = 49 - 5
b = 44

In a lottery, the top cash prize was $615 million, going to three lucky winners. Players pick four different numbers from 1 to 59 and one number from 1 to 49 . A player wins a minimum award of $225 by correctly matching three numbers drawn from the white balls (1 through 59 ) and matching the number on the gold ball (1 through 49 ). What is the probability of winning the minimum award?
Answer:
10063571 out of 593750689 or 1.69491525424%
Step-by-step explanation:
To find probability when all variables are known, you can just multiply the numbers you need. In this case we multiply 59 * 59 * 59 *49 since these are the balls we are picking from. We can find the chance of the top prize by multiplying all the numbers. 59 * 59 * 59 * 59 * 49

Which statements are true for the functions g(x) = x2 and h(x) = –x2 ? Check all that apply.
For any value of x, g(x) will always be greater than h(x).
For any value of x, h(x) will always be greater than g(x).
g(x) > h(x) for x = -1.
g(x) < h(x) for x = 3.
For positive values of x, g(x) > h(x).
For negative values of x, g(x) > h(x).
Answer:
For any value of x, g(x) will always be greater than h(x)
g(x) > h(x) for x = -1
For positive values of x, g(x) > h(x).
For negative values of x, g(x) > h(x).

find the means 01023 234
Answer:
This is not really clear, I will assume that the values in the question are:
{0, 1, 0, 2, 3, 2, 3, 4}
For a set of N elements, {x₁, x₂, ..., xₙ}
The mean of the set is given by:
[tex]Mean = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
In the case of our set, {0, 1, 0, 2, 3, 2, 3, 4}, we have 8 values.
Then the mean of our set is:
[tex]Mean = \frac{0 + 1 + 0 + 2+ 3 + 2 + 3 + 4}{8} = \frac{15}{8} = 1.875[/tex]

The expression 6x - 4 represents the diameter of a circle. The radius is 16 inches. What is the value of x?
Answer: 6
Step-by-step explanation:
Firstly, it should be noted that the diameter of a circle is twice its radius. In this case, the diameter of the circle will be:
Diameter = Radius × 2
Diameter = 16 × 2 = 32 inches
Therefore, to solve for x goes thus:
6x - 4 = 32
6x = 32 + 4
6x = 36
x = 36/6
x = 6
The tree diagram below illustrates the possible outcomes of three tosses of a balanced coin. What is the probability that “heads” will come up exactly two out of three times
please explain step by step
3/8 = 0.375 = 37.5%
====================================================
Explanation:
Start at the very left hand side of the diagram. Also, start at the top as well. So you'll start at "heads". Trace along the top most path and you'll get "heads, heads, heads". This says we got 3 heads in a row. But we want a case where heads only comes up exactly twice. So we rule out this scenario.
Go back to the first "heads". Now trace along the top, but don't land on that third "heads". Instead, go to the "tails" that is underneath in that last column. So you'll have "heads, heads, tails". This time we got exactly two heads out of three tosses. Off to the side somewhere, make a tally of how many times this scenario happens. Another time it happens is when we get "heads, tails, heads". Another time is when you get "tails, heads, heads".
There are only three situations where we get exactly two heads out of three tosses. This is equivalent to the event "getting exactly one tail", so that might be an easier scenario to track down.
If you traced out all of the possible paths, you would find that there are 8 different paths. Note how 2^3 = 2*2*2 = 8 is a numerical way to compute this, due to the fact that each coin toss has 2 outcomes and we have three tosses total.
Since we have three outcomes where we got exactly two heads, out of 8 outcomes total, this leads to the answer being 3/8
Side note: 3/8 = 0.375 = 37.5%
----------------------
We could also solve this problem by listing out all the possible scenarios. I'll use H for heads and T for tails. Something like HHT means we got heads twice in a row, then tails later. The order matters.
Listed below are the 8 possible outcomes. The items in bold represent situations where we get exactly two heads, which is the same as getting exactly one tail.
HHHHHTHTHHTTTHHTHTTTHTTTThe order of each of those eight items is the same as the order if you were to trace out the possible paths of the table given (starting at the top and moving down). We can see that there are 3 cases where we get exactly two 'H's out of 8 possible outcomes total. So that's another way to arrive at 3/8
