The value of x for the given circle will be going to be 50°.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In another meaning, a circle is a geometrical figure whose shape is just like round wheel.

In our daily life, we always see circle objects for example our bike wheel.

Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

Angles of Intersecting Chords Theorem;

When two chords cross inside of a circle, the resulting angle's measure is equal to the product of the lengths of the arcs it intercepts and its vertical angle, divided by two.

So angle x = (60° + 40°)/2  = 50° hence it will be correct answer.

The product of expressions is gotten by multiplying the expressions

The expression that give the same product as 5 * 3/7 is 3 * 5/7

The product expression is given as:

5 * 3/7

Evaluate the product

5 * 3/7 = 15/7

Express 15 as the product of 3 and 5.

So, we have:

5 * 3/7 = 3 * 5/7

Answer:

1 1/2

Step-by-step explanation:

To solve this problem, we need to find how many miles Terry walks in one day. Then, we can multiply by 3 to find how far she walks in three days.

One day |

We need to add how much she walks in both the morning and afternoon. 1/4 + 2/4 = 3/4 miles.

Three days |

Now that we know how much Terry walks in one day, we need to find how much she walks in three days. Multiple by 3 to solve this.

3/4 * 3 = 6/4 = 3/2

You can write 3/2 as an improper fraction: 1 1/2.

Second Option

Step-by-step explanation:

The argument of the log must be greater than zero so

[tex]5 - x > 0[/tex]

[tex] -x > - 5[/tex]

[tex]x < 5[/tex]

So our domain is All Reals less than 5.

The range of log function is all reals so the answer is -oo, oo).

So the second option is the answer.

[tex]-\frac{1}{4}+\frac{3}{4}a=-\left(-\frac{7}{4}a-1 \right)[/tex]

Answer:

Part 1:

-5, a multiplicity of 2

-1, a multiplicity of 1

4, a multiplicity of 3

7, a multiplicity of 1

Part 2: [tex]f(x)=(x+5)^2(x+1)(x-4)^3(x-7)[/tex]

Step-by-step explanation:

This question has to be done visually, and can is a little tricky, because depending on the way the graph intercepts the x-axis, there is going to be a different number of roots.

The roots are represented by the intersection of the function with the x-axis.

To start, take a look at the point [tex](-5,0)\\[/tex], which intercepts the x-axis like a parabola(quadratic function). This means that -5 is a "double root" of the function, or it represents two roots of the function.

Now look at the point [tex](-1,0)\\[/tex], which intercepts the x-axis in a linear way, meaning that -1 is simply a "single-root" of the function, or it only represents one root.

So for the next root, look at [tex](4,0)[/tex], which intercepts the x-axis like a cubic function. This means that 4 is is a "triple-root" of the function, and represents 3 roots of the function.

And finally, we have one final interception at [tex](7,0)\\[/tex], and the interception is in a linear form, meaning 7 is simply a "single-root" to the function, or it only represents one root.

So we can conclude that the following are roots with their respective multiplicities

-5, a multiplicity of 2

-1, a multiplicity of 1

4, a multiplicity of 3

7, a multiplicity of 1

And totally, 2+1+3+1 gives us 7, which supports our answer because we know this is a seventh-degree polynomial.(1)

Now for Part 2

We simply take each root, and subtract it from x in our function, then apply our multiplicity as the exponent

So the function would be: [tex]f(x)=(x+5)^2(x+1)(x-4)^3(x-7)[/tex](2)
