Which of the following shows the graph of a line through (-2,2) and (2,4)

Answers

You didn't include the options, but one and only one line passes through two poins.

You can find the equation of the line that passes through two known points in this way:

[Y -Y1] / [X -X1] = [Y2 - Y1] / [X2 -X1]

in this case (X1,Y1) = (-2,2) and (X2,Y2) = (2,4)

=> [Y - (2) ] / [X - (-2) ] = [4 - 2] / [2 - (-2) ]

=> [Y -2] / [X + 2] = 2/4 = 1/2

=> 2 * (Y - 2) = X + 2

=> 2Y - 4 = X + 2

=> 2Y = X + 2 + 4

=> 2y = x + 6

=> y = x/2 + 3

So you must look the graph of that equation.

Some of the points of that graph are:

x         y

-6       -6/2 + 3 = 0

-4        -4/2 + 3 = 1

-2         -2/2 + 3 = 2

0           0 + 3 = 3

2           2/2 + 3 = 4

4           4/2 + 3 = 5

So, you should find the correspondant graph easily.

Step-by-step explanation:

Given: (-2,2) and (2,4)

Two points are given and to find the equation of line passing through the points.

First we find the slope of the line.

[tex]\text{Slope }=\dfrac{4-2}{2+2}[/tex]

[tex]=\dfrac{1}{2}[/tex]

Point: (2,4)

using point slope form:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-4=\dfrac{1}{2}(x-2)[/tex]

[tex]y=\dfrac{1}{2}x+3[/tex]

Now, we draw the graph using two given points. Plot the points on graph and join them.

Please give brainliest

To find the slope of the line, applying this formula to get it
m=(y2-y1)/(x2-x1) where m represent slope, (x1,y1) represent point (6,-1) and (x2,y2) represent point (7,-2) in this case, so we need to solve it
m=(y2-y1)/(x2-x1)
m=(-2-(-1))/(7-6)
m=(-2+1)/1
m=-1. As a result, the slope of the line passing through the points (6, -1) and (7, -2) is -1. Hope it help!

A projectile is thrown upward so that it's distance above the ground after t seconds is h=-16t^2 +672t. After how many seconds does it reach its maximum height?

Answers

It will reach its maximum height at the vertex of the parabola. Which is always:

(-b/(2a), (4ac-b^2)/(4a))

So the time when this occurs is the x coordinate, or t in this case.

-b/(2a), and b=672 and a=-16 so

t=-672/-32

t=21 seconds

Answer: 21 seconds

Step-by-step explanation:

We know that a parabola with equation [tex]y=ax^2+bx+c[/tex] attains its maximum height at :-

[tex]x=\dfrac{-b}{2a}[/tex]

The given function: [tex]h=-16t^2 +672t[/tex]

It will attain its maximum height at :

[tex]t=\dfrac{-672}{2(-16)}=21[/tex]

Hence , after 21 seconds the projectile will reach its maximum height .

what should be the first step in solving the equation 1.2 W -3.8 equals 12.4

Answers

1.2W - 3.8 = 12.4
1.2W = 12.4 + 3.8
1.2W = 16.2
W = 16.2 ÷ 1.2
W = 13.5

Answer:

Step 1 would be to add 3.8 on both sides.

Step-by-step explanation:

The Equation mentioned in the question is a simple Algebra Equation. We need to solve for W. To do so, we need to get the variable W alone on one side.

Initial Equation: [tex]1.2W-3.8 = 12.4[/tex]

Step 1: Add 3.8 on both sides. [tex]1.2W = 16.2[/tex]

Step 2: Divide 1.2 on both sides. [tex]W = 13.5[/tex]

This gives us the answer of W = 13.5.

True or false the opposite angles of a quadrilateral in a circumscribed circle are always complementary

Answers

Answer: This statement is false.

Step-by-step explanation:

False, the opposite angles of a quadrilateral in a circumscribed circle is not complementary.

As we know that the sum of opposite angles of a cyclic quadrilateral ( quadrilateral circumscribed circle ) is always supplementary.

So, Sum of opposite angles is 180° .

Hence, this statement is false.

Answer:

False

Step-by-step explanation:

We are given that

Opposite angles of a quadrilateral in a circumscribed circle are always complementary.

We have to find that this statement is true or not.

We know that

When a quadrilateral in a circumscribed circle is called cyclic quadrilateral.

We know that

Sum of opposite angles of cyclic quadrilateral is always 180 degrees.

When sum of two angle is equal to 180 degrees then , the angles are called supplementary.

Hence, the sum of opposite angles of cyclic quadrilateral is always supplementary.

Therefore, the given statement is false.

The sum of the first three terms of a convergent geometric series is 19. the sum of the series is 27. find the first term and the common ratio.

Answers

1st,since this GP is convergent that means the common ratio r <1
2nd, sum of a GP = a₁(1-rⁿ)/(1-r), where a₁ = 1st term and n=number of terms
3rd, for any convergent GP, r<1 and the sum of all terms =a₁/(1-r): Why?
[since r<1 → lim rⁿ when n→∞, =0 in the formula of the 2nd)]
Now let's solve :

a) Sum = a₁(1-r³)/(1-r) = 19 (sum of the first 3 terms)
b) Σ(Sum) = a₁/(1-r) = 27 (sum of all terms of this CONVERGENT GP)

Divide a) by b):

[a₁(1-r³)/(1-r)] / [a₁/(1-r)] = 19 /27 ↔ [a₁(1-r³)/(1-r)] x [(1-r)/a₁]=19/27.
Simplify:
(1-r³) = 19/27
-r³ = 19/27 - 1
r³ = 8/27

r = ∛(8/27)

r = 2/3 and a₁ = 9 (Plug r in the Σ sum)
Hence first term a₁ = 9
and common ration r =2/3

The dot plot shows the number of words students spelled correctly on a pre-test. Which statement best describes the shape of the graph?

A.) The graph is skewed right.

B.) The graph is nearly symmetrical.

C.) The graph is skewed left.

D.) The graph is perfectly symmetrical.

Answers

Let's think of this problem easily by looking at it instead of going through rigorous mathematics.

When a graph is skewed right, most of the values are to the left side.

When a graph is skewed left, most of the values are to the right side.

Perfectly symmetrical is that both sides, with respect to the median, are same. Here mean and median is equal.

Nearly symmetrical would really close to perfect symmetry, only varying a bit on both sides. Mean would be approximately equal to median.

Now counting the dots as well as looking closely, we can rule out skewed right and skewed left. Now, is the graph perfectly symmetrical? No! So the correct answer is "nearly symmetrical". Correct choice is B.

ANSWER: B

Answer:

The answer is neary symmetrical or answer B

Step-by-step explanation:

If you cut the graph in half exactly, both side would almost line up perfectly.

The initial temperature of a cup of tea is 200ºF. The surrounding temperature is 70ºF, and the value of the constant k is 0.6. Applying Newton's cooling model, the temperature of the tea after 2 hours will be ºF

Answers

Newton's cooling model is ΔT = ΔTo * e ^ (-k t)

ΔTo = 200°F - 70°F = 130°F

k = 0.6

t = 2 hours

=> ΔT = 130 * e ^ (-0.6 t) = 130 * e^ (-0.6 * 2) = 130 * e ^ (-1.2)

ΔT = 39.15°F

ΔT = T - Tenvironment => T = ΔT + Tenvironment = 39.15°F + 70°F = 109.15°F ≈ 109 °F.

If 1/3 of an office staff is on vacation and 1/4 of those not on vacation are out sick, what fraction of the staff is in the office

Answers

Let x be the total number of staff in the office.

Thus,

The number of staff on vacation = [tex] \frac{1}{3} x[/tex]

Since, it says that staff out sick are among those not on vacation, we have to subtract the number of staff on vacation from the total number of staff.

The number of staff out sick = [tex] \frac{1}{4} (x - \frac{1}{3}x)[/tex]

Hence,

The number of staff in the office = [tex]x - \frac{1}{3} x - \frac{1}{4} (x- \frac{1}{3} x) = (x - \frac{1}{3} x)(1 - \frac{1}{4} ) = x(1- \frac{1}{3})(1- \frac{1}{4}) = x( \frac{2}{3})( \frac{3}{4}) [/tex] [tex]= \frac{1}{4} x[/tex]

There is a traffic light at the intersection of Walnut Street and Lawrence Avenue. The traffic light on Walnut Street follows a cycle. It is green for 50 seconds, yellow for 10 seconds, and red for 30 seconds. As you travel along Walnut and approach the intersection, what is the probability that the first color you see is red?

1/5

1/3

3/5

1/2

Answers

From the given above, we calculate for the total cycle time by adding up all the durations given for the yellow light, red light, and green. That is,
total time = 30 s + 10 s + 50 s = 90s
Hence, the total time is equal to 90 s. From this, we calculate for the probability that the first light that will be seen is a red light by dividing the duration of the red light in the cycle by the total time.
Probability = (30 seconds) / (90 seconds)
= 1/3

Therefore, the probability that the red light will be seen first is equal to 1/3. The answer is second choice.
