If the parabola of equation y=k−x2 is tangent to the line of the equation y=x then what is the value of k ?

The event with the largest probability is rolling a number higher than 2, so the correct option is B.

First, the fact that a 2 was rolled before does not affect the next rolls of the dice, so that information is extra.

Now we just need to see which option has the largest probability.

A) There are only one number lower than 2, then the probability of this event is p = 1/6

B) There are 3 numbers higher than 2, then the probability is p = 3/6 = 1/2

C) The probability of get another 2 is 1/6

We can see that the event with the largest probability is B, so that one is the most likely to occur.

Step-by-step explanation:

The area of the said triangle is 10 cm²

Here we have been given the right-angled triangle with base 5 cm and altitude 4 cm.

To find the area of a triangle we can either use Heron's formula or the other formula where area of a triangle = 1/2 X base X height

Since we have been given the base and the height we need to use the latter.

Hence area of the said triangle will be

1/2 X 5 X 4 cm²

The values of x and y are -1 and 4 respectively.

The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.

Given are two equations, -2x+3y=14 and x+2y=7

Solving equations by using substitution method,

-2x+3y=14..........(i)

x+2y=7

x = 7-2y.......(ii)

Using eq(ii) in eq(i)

-2(7-2y) + 3y = 14

-14+4y+3y = 14

7y = 28

y = 4

Put y = 4 in eq(ii)

x = 7-2(4)

x = -1

Hence, the values of x and y are -1 and 4 respectively.

Answer:

M = (36.5-8)/5

[M = 5.7 miles/day]

Step-by-step explanation:

The goal is 36.5 miles.  The remaining miles needed to achieve this goal is reduced by the miles already ridden, 8 miles.

(36.5 - 8) = 28.5 miles remaining.

We are asked to find a value for M, which is the average number of miles Ian would have to ride to reach his goal.  By average, we can assume it is the average miles/days remaining.  The days remaining are 5, so we have:

(28.5 miles remaining)/5 days = 5.7 miles/day

An equation for M using these steps would be:

M = (36.5-8)/5

The solution is the point where the two lines intersect i.e. (-1,-7). The graph for the given system of equations is attached below wherein the blue line represents y=2x-5 and the green line represents y=-x-8.

What is system of equation?

A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and visual solutions are possible for these equations. The intersection of two lines represents the system of equations' solution.

For solving the equations graphically, we need to find points for plotting

So, for y = 2x-5,

The y-intercept is -5, so we need to place a point on the graph at (0,-5).  For the another point, put x=1, we get y= -3. So we need to place another point at (1,-3).

Similarly for y = -x-8,

The y-intercept is -8, so we need to place a point on the graph at (0,-8).  For the another point, put x=1, we get y= -9. So we need to place another point at (1,-9).

The solution is the point where the two lines intersect.

When the two lines intersect,

2x-5=-x-8

3x=-3

x=-1

So, y=-7

Hence, the two lines intersect at (-1,-7).

The measure of the interior non-adjacent angle as required in the task content is; 95°.

Recall; It follows from the triangle exterior angle theorem that the measure of exterior angle of a triangle is equal to the sum of the two opposite interiors angles.

On this note, if the sculpture’s opposite interior angle is 32 less than the interior non-adjacent angle, the sum of the two angle measures is therefore;

x + x - 32.

where, x is the measure of the interior non-adjacent angle.

Hence, x + x - 32 = 158

2x = 158 + 32

2x = 190

x = 95°.

Ultimately, the measure of the interior non-adjacent angle is; 95°.

As per the following diagram, the angle measures of triangle EFC is 118°

The term angle in math is known as a figure which is formed by two rays or lines that shares a common endpoint.

Here we have given that an artist uses colored tape to divide sections of a mural and she needs to cut a piece of paper to cover triangle EFC while she works on other sections.

According to the diagram, here we know that the value of

=> DE = EF

And the value of

=> EB = FB

Here we know that the value of the angles,

=> ∠EDB = ∠EFB = 90°

Thus implies that the angles,

=> ∠DFB = ∠FEB = 31°

Then the value of the angle is calculated as,

=> ∠EDB =∠EFB = 90° - 31°

=> ∠EDB = ∠EFB = 59°

Then the value of the angle ABC is calculated by sum the values of the angles, then we get,

=> ∠ABC = ∠EDB + ∠EFB = 59 + 59 = 118°

How do you add a fraction?

First you have to check if they have common denominator. If so, add the numerators and keep the denominator. If Not, you have to find common denominator before added. After that,  check if your fraction need to be simplify.

Solve:

Least common multiplier of 10 and 5 is 10

[tex]\frac{3}{10}+\frac{2}{5}[/tex]

Since [tex]\frac{3}{10}[/tex] already have a denominator of 10 we keep it.

[tex]\frac{2}{5}=[/tex] [tex]\frac{2\times2}{5\times2}[/tex] [tex]=\frac{4}{10}[/tex]

Now we have;

[tex]\frac{3}{10}+\frac{4}{10}[/tex]

Apply fraction Rule which is; [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]

[tex]=\frac{3+4}{10}[/tex]

3 + 4 = 7

The graph of the inequality: 3x + y > 7

Can be seen in the image below.

We want to see which graph represents the inequality:

3x + y > 7

We can rewrite the inequality in slope-intercept form as:

y > -3x + 7

So we just need to graph the line:

y = -3x + 7

With a dashed line, and then shade all the region above the line.

To graph the line, you need to find two points that lie on the line.

if we evaluate the line in x = 0 we wll get:

y = -3*0 + 7

y = 7

if x = 1

y = -3*1 + 7

y = -4

Then we have the points (0, -7) and (1, -4), now we can graph these two points and connect them with a dashed line, then shade the region above.

Answer:

Here are two data points that can be used to represent this relationship:

(x1, y1) = (8, $320) - this data point represents that when Susan works 8 hours, she gets paid $320.

(x2, y2) = (12, $440) - this data point represents that when Susan works 12 hours, she gets paid $440.

Step-by-step explanation:

In this situation, the independent variable is the number of hours that Susan works, and the dependent variable is the amount of money that she gets paid.

Here are two data points that can be used to represent this relationship:

(x1, y1) = (8, $320) - this data point represents that when Susan works 8 hours, she gets paid $320.

(x2, y2) = (12, $440) - this data point represents that when Susan works 12 hours, she gets paid $440.

We can use these two data points to represent the relationship between the number of hours that Susan works and the amount of money that she gets paid. It shows that, As her work hours increase, her pay increases as well.

Answer: Yes, after 7 weeks, they will have the same amount of money

Step-by-step explanation: So let’s say Joyce will be equation 1, so it would be - T = 13 + 6x, where T represents the total money, and x represents the number of weeks. And let’s say Enrique will be equation 2, which will be - T = 80 - 5x, where once again, T represents the total money, and x represents the number of weeks.

So, let’s start going off numbers, we will start at 5 weeks, when we put that in, Joyce will have $43 and Enrique will have $65, so we know it will be more than 5 weeks, so let’s try 8 weeks, Joyce will have $61 and Enrique will have $40, so it’s below 8, so how about we try 7, at 7 weeks, Joyce will have $55, and Enrique will have $55 too. So this means, after 7 weeks, Joyce and Enrique will have the same amount of money
