Solution: UP

The angle measure of the minor arc JL equals 82°.

An arc of a circle is defined as the part of the boundary of a circle. The straight line drawn joining the two end points of the arc is called chord of the circle.

If we mark any two points on the circle, by joining those points along the circle, we get two arcs. The smaller arc is called the minor arc and the longer arc is called the major arc. If the length of the arc exactly equals the half length of the circle, then the arc is called semicircular arc.

An arc can be measured in two ways : By finding the measure of the angle of arc and finding the length of the arc.

Here we are asked to find the measure of the minor arc which is the measure of the angle of the arc JL.

Measure of the angle of the arc equals the angle formed at the center of the circle by joining the end points of the arc to the center of the circle.

We have ∠JKL = 82°

∴ measure of arc JL = 82°

Hence, the measure of the minor arc JL equals 82°.

Solving

The degree of a polynomial is categorized by its highest power of its leading variable.

Given the following polynomial functions, we are to classify them based on their degrees and the number of terms

For the polynomial function 5x^4 - 7x + 9

The degree is 4 being quartic and there are three terms in the expression

For the polynomial  2x3 + 3 < 3, the degree is 3 (cubic) with three terms in the expression.

For a Quintic quadnomial​, the degree of the polynomial is 5.

Answer:

6) 152.6

7) 348.4

Step-by-step explanation:

For question number 6, calculate the surface area of the two triangles first. And then, calculate each of the surface area for the rectangles. Finally, total up the area of the two triangles and the rectangles.

[tex](6.6 \times 9) + (4 \times 9) + (5.2 \times 9) \times (\frac{1}{2} \times 5.2 \times 4) = 152.6[/tex]

For question number 7, given that the area of a triangle is 28.4. Hence calculate the area of the three rectangles. Lastly, total up the area of two triangles and three rectangles.

[tex]28.4 + 28.4 + 3(12 \times 8.1) = 348.4[/tex]

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

5x^2 + 55x + 140  ---> required

Coefficients a=5, b=55, c=140 yield

[tex]h=\frac{-h}{2*a} =\frac{-(55)}{2*5} =\frac{-55}{10} =-5.5[/tex]

Thus, the x-coordinate of the vertex is [tex]\boxed{h = -5.5 }[/tex]

Plugging x=-5.5 into the given equation yields:

[tex]k=5*(-5.5)^{2} +55*-5.5+140=-11.25[/tex]

Thus, the y-coordinate of the vertex is [tex]\boxed{k = -11.25 }[/tex]

Altogether, the vertex of the given parabola is

[tex]\boxed{ (h,k)=(-5.5,-11.25) }[/tex]

Plugging (h,k)=(−5.5,−11.25) into the vertex formula

[tex]\boxed{ y=(x-h)^2+k }[/tex]

yields the vertex form of the parabola

[tex]\boxed{ y=(x+5.5)^2-11.25 }[/tex]

Step-by-step explanation:

Range is from -6 to positive infinity or [-6, infinity)

Using the normal distribution and the central limit theorem, it is found that the probability is given by:

e. 0.611

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the parameters are given as follows:

[tex]\mu = 50, \sigma = 10, n = 9, s = \frac{10}{\sqrt{9}} = 3.3333[/tex]

The probability that this sample mean will be between 48 and 54 is the p-value of Z when X = 54 subtracted by the p-value of Z when X = 48, hence:

X = 54:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{54 - 50}{3.3333}[/tex]

Z = 1.2

Z = 1.2 has a p-value of 0.885.

X = 48:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{48 - 50}{3.3333}[/tex]

Z = -0.6

Z = -0.6 has a p-value of 0.274.

0.885 - 0.274 = 0.611, hence option e is correct.

Answer:

[tex] \dfrac{a}{a - 4} [/tex]

Step-by-step explanation:

You are subtracting fractions, so as usual with fraction subtraction, you need a common denominator. To get a common denominator, you need to factor each denominator.

[tex] \dfrac{3a}{a + 4} - \dfrac{2a^2 - 16a}{a^2 - 16} = [/tex]

Factor the right denominator. It is a difference of two squares.

[tex] = \dfrac{3a}{a + 4} - \dfrac{2a^2 - 16a}{(a - 4)(a + 4)} [/tex]

The left denominator is (a + 4). The right denominator is (a - 4)(a + 4). The LCD is (a - 4)(a + 4), so multiply the left fraction by (a - 4)/(a - 4).

[tex] = \dfrac{3a}{a + 4} \times \dfrac{a - 4}{a - 4} - \dfrac{2a^2 - 16a}{(a - 4)(a + 4)} [/tex]

[tex] = \dfrac{3a^2 - 12a}{(a - 4)(a + 4)} - \dfrac{2a^2 - 16a}{(a - 4)(a + 4)} [/tex]

Be careful when you do the subtraction of the numerators, 3a² - 12a minus 2a² - 16a. 3a² - 12a - (2a² - 16a). The minus of the subtraction changes each sign inside the parentheses, so you end up with 3a² - 12a - 2a² + 16a. Be especially careful with the +16a.

[tex] = \dfrac{3a^2 - 12a - (2a^2 - 16a)}{(a - 4)(a + 4)} [/tex]

[tex] = \dfrac{3a^2 - 12a - 2a^2 + 16a}{(a - 4)(a + 4)} [/tex]

[tex] = \dfrac{a^2 + 4a}{(a - 4)(a + 4)} [/tex]

[tex] = \dfrac{a(a + 4)}{(a - 4)(a + 4)} [/tex]

[tex] = \dfrac{a}{a - 4} [/tex]

Answer: 1 and 2

Step-by-step explanation: 1 and 2 because if you are graphing this the formula to find the slope / the line is y = x + some number. In the formula x is how much the line goes from the x axis and the number is how much it is from the y axis. On #2 the problem is 3y = 2x + 4 so to follow the formula you need to divide both sides by 3 to get y = 2/3x + 4. For #3 you do the same thing to get y = -3/2x -5. Finally for #1 the equation is 2x + 3y = 7 so to get the slope / line you need to put x on the other side so now it is 3y = 7-2x then you divide both sides by 3 and get y = -2/3x + 7 and on 1 and 2 there x is 2/3 (the negative doesn't matter and the random number) so they are parallel.
