Determine the equation of the circle graphed below.
Answer:
(x+6)^2+(y-5)^2 = 3.1622^2
Step-by-step explanation:
The equation for a circle can be represented by (x+_)^2+(y+_)^2 = r^2
So, we already can find this portion of the equation knowing the center of the circle:
(x+6)^2+(y-5)^2= r^2
Next, we find the distance between the two given points to find the radius.
6-5 = 1
-3--6 = 3
1^2+3^2 = c^2
1+9= c^2
10=c^2
3.1622...
So, now we know the full equation.
(x+6)^2+(y-5)^2 = 3.1622^2
Tanya is training a turtle for a turtle race. For every 3 of an hour that the turtle is crawling, he can travel 25 of a mile. At what unit rate is the turtle crawling? A 7 of a mile per hour 75 B. of a mile per hour C 37 } miles per hour D. 7 of a mile per hour
Answer:
D. but there should be an 8.33
Step-by-step explanation:
The answer should be 8.33 but in here it only says 7 which is the closest because the unit rate would be 8.33 miles an hour.
7u<42
solve the inequality for U
Answer: u<6
Step-by-step explanation:
Isolate u by dividing both sides of the inequality by 7
[tex]\frac{7u}{7} < \frac{42}{7} \\u < 6[/tex]
u<6
Solution:In order to solve this inequality, we need to divide both sides by 7.Remember, our goal is to find the value of u.We know that 7u is less than 42.So, divide both sides by 7:u<6So u is less than 6.This also means that the numbers less than 6 will satisfy the inequality (make it true).Hope it helps.

Answer: [tex]\frac{5}{6}[/tex] of a yard
=========================================================
Explanation:
The longest is [tex]\frac{6}{6}[/tex] yard and the shortest is [tex]\frac{1}{6}[/tex] of a yard.
This is because 6 is the largest numerator and 1 is the smallest numerator.
Subtract the two fractions:
[tex]\frac{6}{6} - \frac{1}{6} = \frac{6-1}{6} = \frac{5}{6}[/tex]
We subtract the numerators while the denominator stays the same at 6 the entire time.
This is the difference between the longest and shortest ribbon, and the unit is in yards.

Answer:
k = 0, k = 4
Step-by-step explanation:
Given equation:
[tex]y=x^2+kx+3k+4x+4[/tex]
Rearrange into standard form [tex]ax^2+bx+c[/tex]:
[tex]\implies y=x^2+kx+4x+3k+4[/tex]
[tex]\implies y=x^2+(k+4)x+(3k+4)[/tex]
Therefore:
[tex]a=1, \quad b=(k+4), \quad c=(3k+4)[/tex]
If the vertex lies in the x-axis, then the quadratic has one (repeating) root at (x, 0). Therefore, we can use the discriminant to find the values of k.
Discriminant
[tex]b^2-4ac\quad\textsf{when}\:ax^2+bx+c=0[/tex]
[tex]\textsf{when }\:b^2-4ac > 0 \implies \textsf{two real roots}[/tex]
[tex]\textsf{when }\:b^2-4ac=0 \implies \textsf{one real root}[/tex]
[tex]\textsf{when }\:b^2-4ac < 0 \implies \textsf{no real roots}[/tex]
Therefore, set the discriminant to zero and solve for k:
[tex]\implies (k+4)^2-4(1)(3k+4)=0[/tex]
[tex]\implies k^2+8k+16-12k-16=0[/tex]
[tex]\implies k^2-4k=0[/tex]
[tex]\implies k(k-4)=0[/tex]
[tex]\implies k=0, k=4[/tex]
So the vertex lies in the x-axis when k = 0 or k = 4

Answer:

Step-by-step explanation:
So we have the set of numbers: 3,4,4,5,5,2,5,4,6,3,6,5,3.
Mode just means the most repeated number so let's sort them into groups.
(2) (3,3,3) (4,4,4) (5,5,5,5) (6,6).
the most repeated number is 5 which we see in the sequence about 4 times.
Find the equation of a line that passes through the points (-4,-2) and (6, 3).
Answer:
[tex]y = \frac{x}{4} [/tex]
Step-by-step explanation:
we find the slope which also represented as m by the formula
[tex] m = \frac{(y2 - y1)}{(x2 - x1)} [/tex]
where from point (-4, -2) the x1 is -4 and the y1 is -2 and also from point (6, 3) the x2 is 6 and the y2 is 3.
so we substitute
[tex] \frac{(3 - ( - 2))}{(6 - ( - 4))} = \frac{(3 + 2)}{(6 + 4)} = \frac{5}{10} = \frac{1}{2} [/tex]
[tex]m = \frac{1}{2} [/tex]
after we have the slope, we calculate the equation of the line by using the formula
[tex](y - y1) = m(x - x1)[/tex]
but for now, we only have y1, m and x1 so can substitute
[tex](y - ( - 2)) = \frac{1}{2} (x - ( - 4))[/tex]
we have to get rid of the fraction 1/2 so we multiply it through by the denominator 2
[tex]2(y + 2) = 2 \times \frac{1}{2}(x + 4) [/tex]
we get
[tex]2(y + 2) = 1 \times (x + 4)[/tex]
so now we expand the brackets
[tex]2y + 4 = x + 4[/tex]
we make y stand alone by grouping liked terms.
[tex]2y = x + 4 - 4[/tex]
we get
[tex]y = \frac{x}{4} [/tex]
Please help! I cannot figure this out, I have no idea what to do.
3. First you should identify which line corresponds to which equation.
x + 2y = -8 ⇒ y = -x/2 - 4
is the line with slope -1/2 and intercept (0, -4), so the first inequality refers to the lower line in the graph.
For the inequality itself, the solution set that satisfies it is either the region above or below it. To decide which, pick any point in the plane and plug its coordinates into the inequality. The origin is a natural choice, since it's not on the line and working with 0s is easy.
In the first inequality, we have
x = 0 and y = 0 ⇒ 0 + 2•0 = 0 < -8
which is not true. So (0, 0) is not in the solution set, and it stands to reason that any point in the same region will not be a solution. In other words, the region above the line x + 2y = -8 does not satisfy the inequality, while the one below it does.
In the second inequality,
x = 0 and y = 0 ⇒ 2•0 + 0 = 0 ≥ -1
which is true. This means the region containing (0, 0) above the upper line solves the second inequality.
The solution to the system of inequalities is then the intersection of these two regions. (See attached; I've labeled the solution to the first inequality in blue, the solution to the second one in red, and the solution to both in green.)
All this work is kind of overkill for this particular question, though. All you really need to do is check if the given point satisfies the inequalities:
• (-5, 5) :
x = -5 and y = 5 ⇒ -5 + 2•5 = 5 < -8 ⇒ NO
• (2, -5) :
x = 2 and y = -5 ⇒ -2 + 2•5 = 8 < -8 ⇒ NO
• (-4, -6) :
x = -4 and y = -6 ⇒ -4 + 2•(-6) = -16 < -8 ⇒ MAYBE
x = -4 and y = -6 ⇒ 2•(-4) + (-6) = -14 < -8 ⇒ YES
• (5, -7) :
x = 5 and y = -7 ⇒ 5 + 2•(-7) = -9 < -8 ⇒ MAYBE
x = 5 and y = -7 ⇒ 2•5 + (-7) = 3 < -8 ⇒ NO
4. x is the number of candy boxes with chocolates and y is the number of boxes without chocolates. Each of the x boxes cost $27.50, so if you have x boxes, their total cost is $27.5x. Each of the y boxes cost $25.00, so y boxes cost $25y. The sponsor doesn't want to order more than 100 boxes total, so
x + y < 100
but wants to raise at least $2000, so
27.5x + 25y ≤ 2000
Now do the same thing as before; plug in the listed x- and y-coordinates and pick the point that satisfies both inequalities. You will find that (50, 30) is the correct choice.
5. Consult the "overkill" part of problem 3. The line y = -3x + 6 has a negative slope, so it's the downward sloping one. Check if the origin satisfies the inequality:
x = 0 and y = 0 ⇒ 0 ≤ -3•0 + 6 ⇒ 0 ≤ 6 ⇒ YES
This means Regions II and III solve the first inequality.
Do the same with the other inequality:
x = 0 and y = 0 ⇒ 0 ≥ 1/2•0 + 1 ⇒ 0 ≥ 1 ⇒ NO
This tells us that Regions I and II solve the second inequality.
The intersection of these regions is of course Region II.
6. One of the plotted lines is apparently y = x + 4, which has a positive slope, so this must be the upper line. The shaded region below it corresponds to the solution of either y < x + 4 or y ≤ x + 4 and we eliminate B.
The other line has negative slope, which eliminates A and D since
3x - 4y = 20 ⇒ y = 3/4x - 5
has positive slope. This leaves D.
Mr. and Mrs. Doran have a genetic history such that the probability that a child being
born to them with a certain trait is 0.61. If they have four children, what is the
probability that at most two of their four children will have that trait? Round your
answer to the nearest thousandth.
Using the binomial distribution, it is found that there is a 0.011 = 1.1% probability that exactly one of their four children will have that trait.
For each children, there are only two possible outcomes, either they have the trait, or they do not. The probability of a children having the trait is independent of any other children, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X=x)=C_{n,x.}p^x.(1-p)^{n-x}[/tex]
[tex]C_{n,x}=\frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
85% probability of a children having the trait, hence [tex]p=0.85[/tex].They have four children, hence [tex]n=4[/tex]The probability is P(X = 1), hence:
[tex]P(X=x)=C_{n,x.}p^x.(1-p)^{n-x}[/tex]
[tex]P(X=1)=C_{4,1*}(0.85)^1.(0.15)^3=0.011[/tex]
0.011 = 1.1% probability that exactly one of their four children will have that trait.
