Answer:
41 minutes before noon
Step-by-step explanation:
The given parameters are;
The time camera A starts taking pictures = 6 AM
The frequency of picture taking by camera A = Once every 11 minutes
The time camera B starts taking pictures = 7 AM
The frequency of picture taking by camera B = Once every 7 minutes
The number of times both cameras take a picture at the same time before noon = 4 times
Let the time the two cameras first take a picture the same time be x, we have;
11·y - 60 = x
7·z = x
Taking the number of times after 7 camera A snaps and noting that the first snap is 6 minutes after 7, we have
11·b + 6 = x
7·z = x
x is a factor of 7 and 11·b + 6 and x is some minutes after 7
By using Excel, to create a series of values for Camera A based, on 11·b + 6, and dividing the results by 7 we have the factors of 7 at;
28, 105, 182, and 259 minutes after 7
Given that there are 60 minutes in one hour, we have;
259/60 = 4 hours 19 minutes, which is 11:19 a.m. or 41 minutes before noon.

Consider the equation: 12x=13-x^212x=13−x 2 12, x, equals, 13, minus, x, squared 1) Rewrite the equation by completing the square. Your equation should look like (x+c)^2=d(x+c) 2 =dleft parenthesis, x, plus, c, right parenthesis, squared, equals, d or (x-c)^2=d(x−c) 2 =dleft parenthesis, x, minus, c, right parenthesis, squared, equals, d. 2) What are the solutions to the equation
Answer:
[tex](x + 6)^2 = 49[/tex]
[tex]x = 1[/tex] or [tex]x = -13[/tex]
Step-by-step explanation:
Given
[tex]12x = 13 - x^2[/tex]
Using Completing the Square
[tex]12x = 13 - x^2[/tex] ---- Add [tex]x^2[/tex] to both sides
[tex]x^2 + 12x = 13 - x^2 + x^2[/tex]
[tex]x^2 + 12x = 13[/tex]
Divide the coefficient of x by 2; then add the square to both sides
[tex]x^2 + 12x + 6^2 = 13 + 6^2[/tex]
[tex]x^2 + 12x + 36 = 13 + 36[/tex]
[tex]x^2 + 12x + 36 = 49[/tex]
Factorize
[tex]x^2 + 6x + 6x + 36 = 49[/tex]
[tex]x(x + 6) + 6(x + 6) = 49[/tex]
[tex](x + 6)(x + 6) = 49[/tex]
[tex](x + 6)^2 = 49[/tex]
Hence, the equation is [tex](x + 6)^2 = 49[/tex]
Solving further
Take square root of both sides
[tex](x + 6) = \sqrt{49}[/tex]
[tex]x + 6 = \±7[/tex]
[tex]x = \±7- 6[/tex]
This implies that
[tex]x = 7 - 6[/tex] or [tex]x = -7 -6[/tex]
[tex]x = 1[/tex] or [tex]x = -13[/tex]
HEnce, the solutions are [tex]x = 1[/tex] or [tex]x = -13[/tex]
Answer:
(x+6)^2=49 and x=−6±7

Please help me I promise I will mark you brainliest if you are correct!!!!!!!!!!!!!!!!!!!!!!!!!! Use the graph of f to estimate the local maximum and local minimum. A quadratic graph is shown. The graph intercepts the x axis at approximately -2.8 and 1.2. A). No local maximum; local minimum: approx. (1,-7.67) B). Local maximum: (-2,8); local minima: (-3,0) and (3,3) C). Local maximum: approx. (1,8.08); local minima: approx. (-2,-7.67) and (3,2.75) D). Local maximum: ∞ local minima: (-3,0) and (3,3)
Answer:
Local Maximum Approx.: (1,8.08)
Local Minima Approx.: (-2,-7.67) and (3,2.75)
Step-by-step explanation:
Local maximums and minima there the highest and lowest points, respectively, on a graph in a specific region. (This is different from absolute maximum and minimum, which are the highest and lowest points overall.)
These are pretty clear to see on a curve, as they are the "turns" or the points where the curve switches direction from up to down or down to up.
On your graph, we have two local minima and one local maximum. The local minima are at x= -2 and x=3. The local maximum is at x=8. Because of the way the graph is, we have to approximate the y-values of each point.

[tex]\boxed{x = -5/21}[/tex]
Step-by-step explanation:
Hey there!
To simplify we need to combine like terms and use the communicative property,
34x + 6 = 1 + 13x
-13x to both sides
21x + 6 = 1
-6 to both sides
21x = -5
Divide both sides by 21
x = -5/21
Hope this helps :)
Answer: I'm guessing you need me to solve this for you.
I interpreted the equation this way: 34x + 6 = 1 + 13x
The solution is -5/21.
Step-by-step explanation:
34x + 6 = 1 + 13x
Step 1: Simplify both sides of the equation.
34x + 6 = 13x + 1
Step 2: Subtract 13x from both sides.
34x + 6 − 13x = 13x + 1 − 13x
21x + 6 = 1
Step 3: Subtract 6 from both sides.
21x + 6 − 6 = 1 − 6
21x = − 5
Step 4: Divide both sides by 21.
21x/21 = -5/21
x = -5/21

Sandra spotted the sailboat from the shore and measured the angle from the waterline to the top of the boats mast to be 7° if the top of the mask is 23 feet above the water how far is the middle of the sailboat from the shore? Estimate your answer to the nearest tenth.
Answer:
The middle of the sailboat is approximately 268.8 feet from the shore.
Step-by-step explanation:
Let the distance from shore to the middle of the boat be represented by x, the angle of elevation of Sandra from the shore to the top of the boat mast is 7°. Applying the required trigonometric function to this question, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan 7° = [tex]\frac{23}{x}[/tex]
⇒ x = [tex]\frac{23}{Tan 7^{0} }[/tex]
= [tex]\frac{23}{0.12279}[/tex]
= 268.7515
∴ x = 268.8 feet
The middle of the sailboat is approximately 268.8 feet from the shore.

The number can be divisible by 7.
The multiples of 7 are 7,14,21,28,35,42,49,56,63,70,77,84 and so on
Finding the factors for all of the multiples of 7:
7 => 1,7 [Not 4 factors]
14 => 1,2,7,14 [4 factors but Sum = 24]
21 => 1,3,7,21 [4 factors but Sum = 32]
28 => 1, 2, 4, 7, 14, 28 [Not 4]
35 => 1,5,7,35 [4 factors but Sum = 48]
42 => 1, 2, 3, 6, 7, 14, 21, 42 [Not 4]
49 => 1,7,49 [Not 4]
56 => 1, 2, 4, 7, 8, 14, 28, 56 [Not 4]
63 => 1, 3, 7, 9, 21, 63 [Not 4]
70 => 1, 2, 5, 7, 10, 14, 35, 70 [Not 4]
77 => 1, 7, 11, 77 [4 factors and Sum = 96]
Answer:
77
Step-by-step explanation:
The first factor is 1
Since it is divisible by 7, 7 will also be one of its factors.
Therefore the four factors are
1, 7, x, y
When x and y are integers
Using the following law...
The product of factors of a number in the same position (left or right) (increasing or decreasing order) is equal to the number
Counting from left
y is the first factor
x is the second factor
Counting from the right
1 is the first factor
7 is the second factor
Applying the last
y×1=x×7
y = 7x
the sum of the factors is 96
1+7+x+7x = 96
8x+8=96
8x = 88
x= 11
Hence the number is
7x = 7(11)

For what value of k does the equation (2k+1)x^2+2x=10x-6 have two real and equal roots?
Answer:
[tex]\displaystyle k = \frac{5}{6}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle (2k+1)x^2 + 2x = 10x - 6[/tex]
And we want to find the value of k such that the equation has two real and equivalent roots.
Since the equation is a quadartic, we can find its discriminant (symbolized by Δ). Recall that:
If Δ < 0, we have no real roots (two complex roots). If Δ > 0, we have two real roots. And if Δ = 0, we have one real root, or two equivalent ones.First, rewrite our equation:
[tex](2k+1)x^2 -8x + 6 =0[/tex]
The discriminant is given by:
[tex]\displaystyle \Delta = b^2 -4ac[/tex]
In this case, b = -8, a = (2k + 1), and c = 6.
Therefore, the discriminant is given by:
[tex]\displaystyle \Delta = (-8)^2 - 4(2k+1)(6)[/tex]
For it to have two equal roots, the discriminant must be zero. Hence:
[tex]\displaystyle 0 = (-8)^2 - 4(2k+1)(6)[/tex]
Solve for k:
[tex]\displaystyle \begin{aligned} \displaystyle 0 &= (-8)^2 - 4(2k+1)(6) \\ 0 &= 64 - 48k - 24 \\ 0 &= 40 - 48k \\ -40 &= -48k \\ \\ k &= \frac{5}{6} \end{aligned}[/tex]
Hence, the value of k is 5/6.

Outliers can cause the _________ to be misleading when summarizing a data set.
A. mean
B. interquartile range
C. all of these
D. median
Answer:
A. Mean
Step-by-step explanation:
Mean, because it's the average of the numbers and if one number's way off, it would throw the average off by a lot! I honestly forgot a bit about interquartile ranges, but it doesn't affect the median at all/have a very little effect so that's why it's not all of these. But mean is for sure!

Find the value of z. A. 141 B. 110 C. 80 D. 100
Answer:
B. 110
Step-by-step explanation:
z is supplemental to 70°, so the add up to 180°
z+70°=180°
z=180°-70°
z=110°
Option B is correct. The required value of z is 110 degrees
Supplementary angles are angles summing up to 180 degrees. According to the circle geometry, we can see that z and 70 degrees lie on the same line, this shows that both angles are supplementary.
Since supplementary angles sum up to 180degrees, hence;
[tex]z + 70 = 180\\[/tex]
Subtract 70 from both sides
[tex]z+70-70=180-70\\z=110^0[/tex]
Hence the value of z is 70 degrees

If the functions f(x) and g(x) are
increasing on an interval, is the
interval? how about f(x) – g(x)?
Answer:
The difference will be increasing too
Step-by-step explanation:
If f(x) and g(x) is increasing in nature then
f(b) < f(a) and g(b) < g(a) for any a and b in the interval.
Subtracting these 2 equations, we get
f(b) - g(b) < f(a) - g(a) for any a and b in the interval.
Which means f-g is increasing in the interval (a, b) but as a and b were random real numbers we took, f(x) - g(x) will be increasing for an interval

a=4 b = 8 c=9
The discriminant is
b^2 -4ac
8^2 - 4(4)(9)
64 - 144
-80
Answer:
-80
Step-by-step explanation:
The discriminant is the value under the radical in the quadratic formula. The part of the quadratic formula that is under the radical is [tex]\sqrt{b^2-4ac}[/tex]. So, plug in the needed values and solve for what is under the radical. The b-value is 8; this squared is 64. Then, plug in a and c, 4 and 9. Then multiply these by 4, 4*4*9=144. Finally subtract, 64-144=-80.
