Answer: 3/-4

The slope is measured in terms of rise over run. Rise is how many units you go up or down from the point (0, 0). Run is how many units you go left to right from the point where rise left off.  For this question, we go up 3 and to the left 4. SO that's a 3 on top and a -4 on the bottom.

Based on the area of T, the area of U can be calculated to be 272 cm²

When you have an object that is enlarged and have the area of the object before it was enlarged, the area of the enlarged object is:

= Area of original object x Scale factor of enlargement ²

The scale factor is:

= Side of U / Corresponding side of T

= 12 / 3

= 4

The scale factor is 4.

The area of U is therefore:

= 17 x 4²

= 272 cm²

Using linear functions, it is found that:

1. The functions are given as follows:

2. They will have the same elevation after 18.4 minutes.

3. At that time, the elevation is of 18,150 feet.

A linear function is modeled in slope-intercept form by:

y = mx + b

In which:

For the functions in this problem, we have that:

Hence the functions are given as follows:

They will have the same elevation when:

E1(t) = E2(t)

28270 - 550t = 5270 + 700t

1250t = 23000

t = 23000/1250

t = 18.4.

They will have the same elevation after 18.4 minutes.

This elevation will be of:

28270 - 550(18.4) = 18150.

At that time, the elevation is of 18,150 feet.

One Variable in the linear equation :

The linear equation in one variable is an equation that is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2. Whereas if we speak about linear equations in two variables, it has two solutions.

The probability of a random probability of a random student being chosen who is a female and is not between the ages of 18 and 20 will be 0.06.

From the information, 53% of its students are male (M), 37% of its students are between the ages of 18 and 20 (A), and that 31% are both male and between the ages of 18 and 20.

Probability to females = 100% - 53% = 47%

Therefore, the probability of a random student being male or between the ages of 18 and 20 will be:

= 37% - 31%

= 6%

Therefore, the probability of a random student being female or between the ages of 18 and 20 will be 6%.

c) The sequence means that the number of blocks start at 5 and increase by 3 each figure.

3) The 4th term of the sequence is of -3.

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

From the figure, we have that:

Hence the first term and the common ratio are given as follows:

[tex]a_1 = 5, d = 3[/tex]

The sequence is: [tex]a_n = 5 + 3(n - 1)[/tex], hence the sequence means that the number of blocks start at 5 and increase by 3 each figure.

The correct answer is 8 cm.

Given the surface area = 518 cm²

breadth of the cuboid = 11 cm

height of the cuboid = 9 cm

Now let l be the length of the cuboid,

The total surface area (TSA) of a cuboid is provided by the sum of the areas of its six rectangles, where l, b, and h are the length, width, and height, respectively

Cuboid's total surface area formula,

Thus the surface area of the cuboid = 2(lb+bh+lh)

518 = 2 ( l × 11 + 11 × 9 + l × 9 )

518 = 2 (11l + 99 + 9l)

259 = 11l +99 +9l

259 - 99 = 20 l

Answer: Find [tex]2^{21} = (2y)^{3}[/tex] then the solution of [tex]y^{3}[/tex] = [tex]2^{7}[/tex]

Step-by-step explanation:

Given data,

[tex](a^{m)^{n} }[/tex] = [tex]a^{m*n}[/tex] says that when you take a number, a , and multiply it by itself m times, then multiply that product by itself n times, it's the same as multiplying the number a by itself m * n times.

we can use formula,

                    [tex](a^{m)^{n} }[/tex] = [tex]a^{m} a^{n}[/tex]

So,

we can write,

                       [tex]2^{21}[/tex] = [tex]2^{3} y^{3}[/tex]

                        [tex](2^{7} )^{3}[/tex] = [tex]2^{3} y^{3}[/tex]

                          [tex]2^{7} 2^{3}[/tex] = [tex]2^{3} y^{3}[/tex]

cancel the [tex]2^{3}[/tex] in both sides,

Then,

Answer:

y=x+6

Step-by-step explanation:

First, write out the slope intercept equation.

y=mx+b

Ok, the first step for finding a linear equation is finding the y-intercept. The line crosses the y-axis at 6, so the y-intercept is 6. Plug that into the slope-intercept Equation:

y=mx+6

Then, slope is rise over run, and the line goes up 1 and right 1 to get to the next point, so divide those numbers.

1/1=1

Then plug that into your slope intercept equation:

y=1x+6

Since the one won't do anything, it will just be this:

y=x+6

Using a transformation of the parent function y = x², the graph of f(x) = (x + 5)² is given at the end of the answer.

Transformations in the graph of a function involve operations such as multiplication/division or sum/subtraction, either in the domain of the function, involving values of x, or the range, involving values of y.

Examples of transformations are as follows:

For this problem, the parent function is given by:

f(x) = x².

Which has a parabolic graph with vertex at (0,0).

For f(x) = (x + 5)², we have that x -> x + 5, meaning that the function is shifted 5 units left, meaning that the parabola has a vertex at (0,-5), and the graph is given at the end of the answer.

A quadratic function is one that has the formula f(x)=ax2+bx+c, where a, b, c, and an are all real values and a 0 a 0. The conventional form of a quadratic function is this form.

The quadratic function's graph is a U-shaped curve known as a parabola.

Below is a graph of the equation y=x2y=x2; it is a parabola.

The parabola rises if a>0a>0 in f(x)=ax2+bx+cf(x)=ax2+bx+c.  In this case, the vertex is the smallest or lowest point of the parabola.

The vertex of the y=x2y=x2 graph is (0, 0). (0,0).

The parabola opens downhill if a0a0 in f(x)=ax2+bx+cf(x)=ax2+bx+c is true. The maximal or highest point of the parabola in this instance is called the vertex.

The value of cc for an equation in standard form yields the graph's yy-intercept.

The axis of symmetry is the line that divides the parabola into two symmetric sections and runs through the vertex.

In the case of the graph y=ax2+bx+cy=ax2+bx+c, where a=0a=0, the equation for the axis of symmetry is x=b2ax=b2a.

The yy-axis, with x=0x=0, is the axis of symmetry in all of the graphs above. The axis of symmetry in the graphs below is different (marked in red.) As you can see, cc still provides the yy-intercept.

If you write a quadratic function like x=f(y)=ay2+by+cx=f(y)=ay2+by+c, instead of writing yy as a function of xx, you obtain a parabola with a horizontal axis of symmetry.

Hence, that the xx-intercept in this situation is cc. When aa is positive, the graph opens to the right; when aa is negative, it opens to the left.
