Pythagorean theorem hw

Answer: A

Step-by-step explanation:

If you look at option A and ignore the -(x+2)^2, it would say f(x) = -3.

So the vertex has y-coordinate -3.

Because the coefficient of -(x+2)^2 is negative, the graph opens downward.

Because it says -(x+2)^2 instead of -(x-2)^2, it will be on the left side of the graph.

The graph meets all of these conditions.

The graph described in option B opens upwards.

The graph described in option C opens upwards and the vertex is in the fourth quadrant.

The graph described in option D opens downwards, but the vertex is in the fourth quadrant.

Answer:

It's D I think.... Line up B and C with M,N

Answer:

  c ∈ {3.4, 20.6}

Step-by-step explanation:

The law of cosines can be used to write a quadratic equation in c.

  a^2 = b^2 + c^2 -2bc·cos(A)

  10^2 = 13^2 + c^2 -2(13)c ·cos(23°)

  c^2 -23.933c +69 = 0 . . . . . subtract 100 to put into standard form.

  c = (-(-23.933) ±√((-23.933)^2 -4(1)(69)))/(2(1))

  c ≈ 11.967 ± √74.199

  c ≈ {3.4, 20.6}

Additional comment

The given angle is opposite the shorter of the two given sides, so we expect two solutions. We could use the law of sines, but this works just as well and gives the two solutions directly, without having to find angle B.

Answer:3

Step-by-step explanation:

Given:

In triangle ABC, Q is the centroid and FQ=9.

To find:

The length of FC and QC.

Solution:

We know that, centroid is the intersection point of medians of a triangle and medians divide teach other in 2:1. So, centroid divided each median in 2:1.

CF is a median and Q is the centroid. So,

[tex]QC:FQ=2:1[/tex]

Let the length of QC and FQ are 2x and x respectively.

We have, FQ=9.

[tex]x=9[/tex]

Now,

[tex]QC=2x[/tex]

[tex]QC=2(9)[/tex]

[tex]QC=18[/tex]

And,

[tex]FC=FQ+QC[/tex]

[tex]FC=9+18[/tex]

[tex]FC=27[/tex]

Therefore, the length of FC is 27 units and length of QC is 18 units.

Step-by-step explanation:

Inches to CM Conversion

1 Inch (in) is equal to 2.54 cm. To convert inches to cm, multiply the inch value by 2.54. For example, to find out how many cm is 12 inches, multiply 12 by 2.54, that makes 30.48 cm is 12 in.

Answer:

81 + 81 + 10 aka 172

Step-by-step explanation:

Answer:

172

Step-by-step explanation:

z = 9

9 to the second power is 81

9 times 9 is 81

plus 10

= 172

Answer:

linear

Step-by-step explanation:

if you have access to a graphing calculator then enter the equation and you can see it forms a line

if you have graph paper, create some coordinates, plot and connect them

example of some ordered pairs could be:

(0, 7)

(2, 6)

(-2, 8)

Answer:

B. 16.9

Step-by-step explanation:

Reverse Pythagoreans theorem C^2 - B^2 = A^2 so

7^2 - 5^2 = c^2 and it comes out to

49-25 = 24 the square root of that is 4.9 (rounded)

But we are lookign for the perimeter so

4.9 + 7 + 5 = 16.9

Answer:

a. 3 > -3

C. -12 > -24

b. 12< 24

d. 5 = -(-5)

Step-by-step explanation:

Answer:

The x- and y-coordinates are switched

Step-by-step explanation:

Here, we want to identify the error in the plot

1.5 units to the left, that is negative x-axis (-1.5)

4 units up is 4

So the coordinate point is (-1.5,4)

So the error on what he gave was that both coordinates were switched

Answer:

-1

Step-by-step explanation:

First, order the list of number from least to greatest:

-19 , -11 , -11 , - 5 , -1 , 0 , 2 , 10 , 16

Next, note the definition of a median. The median number is the number in the middle of a given set of numbers. In this case, it is -1.

-1 is your median.

Answer:

18

Step-by-step explanation:

Because 85 divided by 5 is 17 add 1 for the missing 3 boom 18.

Answer:

D) 18 marbles will be red

Step-by-step explanation:

We know that the order is Yellow, green, red, blue, brown due to it saying “in the order given”

We can say that every time 1 of each marble of these colors are dropped in we can make that a set and since and we know there are 5 marbles a set.

Now we know there are 88 marbles so we divide

88/5= 17 Remainder: 3

Now 17 sets so we know there are at least 17 of each marble In the jar

Now the remainder of 3

Following the order

1 would go into yello, 1 to green, and the last one to red

So thats an extra plus 1

Now we have

Yellow: 17+1=18

Green: 17+1=18

Red: 17+1=18

Blue: 17

Brown: 17

So there are 18 red marbles

CHECK:

We add all the final results and see if we get 88

18*3 (becuase there are 3, 18s)

18*3+17*2 (same for 17s, ther are 2 17s)

18*3=54

17*2=34

54+34=88

So its true

Answer:

[tex]a_n = 1 + 5(n-1)[/tex]

$36

Step-by-step explanation:

I think the part that is confusing you is how to read the math syntax.

The part that says "[tex]a_n=1, if\ n=1[/tex]" just means that a=1 is your starting number. The n=1 is the first iteration.

The part that says "[tex]a_{n}=a_{n-1}+5\ , if\ n>1[/tex]" just means that you add 5 to the previous number every iteration.

They want you to find the number at 8th iteration, n=8. So lets work it out.

n=1:  a= 1

n=2: a= 1+5 = 6

n=3: a= 6+5 = 11

n=4: a= 11+5 = 16

n=5: a= 16+5 = 21

n=6: a= 21+5 = 26

n=7: a=26+5 = 31

n=8: a= 31+5 = 36

Or you can use the shortcut:

You're always adding by 5 each time and starting with 1, so:

[tex]a_n = 1 + 5(n-1)[/tex]

where n=8 for the 8th round.

[tex]a_n = 1 + 5(8-1) = 36[/tex]

Answer:

b = (a - 6)/V

Step-by-step explanation:

a = Vb + 6​

Subtract 6 from both sides:

a - 6 = Vb

b = (a - 6)/V

6

Answer:

[tex] - 12 \geqslant - 13 \\ \geqslant - 13 + 12 \\ \geqslant - 1 [/tex]

The required solution to the given inequality q - 12 ≥ -13 would be q ≥ -1. The correct answer would be an option (B).

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality is given in the question, as follows:

q - 12 ≥ -13

We have to determine the solution to the given inequality

As per the question, we have

⇒ q - 12 ≥ -13

Add 12 on both sides of the above inequality

⇒ q - 12 + 12 ≥ -13 + 12

⇒ q ≥ -1

Therefore, the required solution to the given inequality would be q ≥ -1.

Hence, the correct answer would be an option (B).

Answer:

The equation of line in point slope form is: [tex]\mathbf{y+5=-\frac{2}{3} (x-4)}[/tex]

Option A is correct option.

Step-by-step explanation:

We need to identify an equation in point-slope form the line parallel to y=-2/3x+8 that passes through(4, -5).

The general equation of point slope form is: [tex]y-y_1=m(x-x_1)[/tex]

where m is slope of the equation.

Finding slope of the equation.

Since the two lines are parallel so, both lines have same slope.

Equation of given line: y=-2/3x + 8

This equation is in slope-intercept form, comparing with general equation [tex]y=mx+b[/tex] where m is slope , we get the value of m= -2/3

So, slope of given line = m = -2/3

Slope of required line = m =-2/3

Now, writing equation in point-slope form:

We are given point (4,-5) so, we have [tex]x_1=4, y_1=-5[/tex] and slope is: m=-2/3

So, equation of line in point-slope form is:

[tex]y-y_1=m(x-x_1)\\y-(-5)=-\frac{2}{3}(x-4)\\y+5=-\frac{2}{3}(x-4)[/tex]

So, the equation of line in point slope form is: [tex]\mathbf{y+5=-\frac{2}{3} (x-4)}[/tex]

Option A is correct option.

Answer: No.

Step-by-step explanation: A function means that for every x, there is only ONE y value. In this case, 6 can be either -1 or 5, which is more than one value.

Answer:

The given set is NOT a function

Step-by-step explanation:

A function is a given set of data in which no x values repeat, where y values may or may not repeat. Since this given set does have a x value that repeats, it is not a function!
