okay so the problem is "A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is ( ) units. the point (-7, ) lies kn this circle. I'm not sure how to find the answer.
Answer:
A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.
Step-by-step explanation:
equation of circle is
(X-center_X)^2 + (y-center_Y)^2 = r^2
==> (x+3)^2 + (y-2)^2 = r^2
Now it passes 1,5 so
4^2+3^2 = 5^2
==> r = 5
when x = -7
y = -1 or 5

Correct method to factor this expression are:
Factor by grouping.
Factor out the GCF.
What is factorization?A number or other mathematical object is factorised or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. The four primary methods of factoring are the Grouping technique, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF). Numerous issues might be resolved by using the factoring of integers. Similar to this, factoring is an extremely effective method in algebra that is utilised at all levels. It offers a common approach to simplifying complex statements as well as, of course, solving quadratic equations.
The equation becomes:
= 4x² - 26x + 30
= 2 (2x² - 13x + 15)
= 2 (2x² - 10x - 3x + 15)
= 2 {2x (x - 5) - 3 (x - 5)}
= 2 (2x - 3) (x - 5)
Thus, the two methods are the best choices to factor this express are:
Factor by grouping.
Factor out the GCF.

In ΔJKL, the measure of ∠L=90°, KL = 11 feet, and JK = 32 feet. Find the measure of ∠J to the nearest tenth of a degree.
Answer: J = 20.1
Step-by-step explanation:
sin J = hypotenuse/opposite = 11/32
Sin J =11/32
J=sin-1(11/32)

Solve for x. Enter your answer in interval
notation using grouping symbols.
x2 + x < 20
Answer:
x<18
Step-by-step explanation:
2+x<20
Answer:
(-5, 4)
Step-by-step explanation:
x^2 + x < 20 can be rewritten as a quadratic in standard form: x^2 + x - 20 < 0. Recognize that the graph of x^2 + x - 20 is that of a parabola that opens up. Because the y-intercept (0, -20) is below the x-axis, we know for certain tht the graph intersects the x-axis in two places. Our job is to determine the two horizontal intercepts, which in turn determine the solution set.
x^2 + x - 20 = 0 factors as follows: (x + 5)(x - 4) = 0, whose roots are -5 and 4.
These two roots form 3 intervals: (-infinity, -5), (-5, 4) and (4, infinity). We now must identify on which intervals x^2 + x - 20 is less than 0 (that is, on which intervals the graph is below the x-axis). Choose three test values for x: the first could be -6 (which is in the set (-infinity, -5) ); x^2 + x - 20 is + there, and so the graph is above the x-axis and x^2 + x - 20 is positive. Reject this.
Next, test x = 0; x^2 + x - 20 is negative there, meaning that x^2 + x - 20 < 0 and that x^2 + x < 20. Thus, the solution is (-5, 4). It can be shown that x^2 + x - 20 is positive again for x-values within the interval (4, infinity).

A store manager combines 2 lb of trail mix that contains some cashew nuts with 30 lb
of trail mix that is 20% cashews. The result is a trail mix that is 25% cashews. What is the concentration of cashews in the first mixture?
Answer:
100%
Step-by-step explanation:
Let p = percent of cashews in first mix
2p = lb. of cashews in first mix
30(.20) = 6 = lb. of cashews in second mix
32(.25) = 8 = lb. of cashews in the combined mix
So,
lb. of cashews in first mix + lb. of cashews in second mix = lb. of cashews in the combined mix
2p + 6 = 8
2p = 2
p = 1 = 100%
Answer:
100%

Write the equation in Point-Slope Form given the Slope is 5 and passes through the Point (-2, 10).
Answer:
y-10=5(x+2)
Step-by-step explanation:
y-y1=m(x-x1)
y-10=5(x-(-2))
y-10=5(x+2)
Answer:
y - 10 = 5(x + 2)Step-by-step explanation:
The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)
m = 5
x₁ = -2
y₁ = 10
Therefore the equation:
y - 10 = 5(x + 2)(29 points!!!)Enter the correct answer.

Use trigonometry to work out the size of angle x. Hypotenuse= 10cm, Adjacent= 9cm
9514 1404 393
Answer:
25.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the trig relations in a right triangle.
Cos = Adjacent/Hypotenuse
cos(x) = (9 cm)/(10 cm) = 0.9
Using the inverse cosine function, we can find the angle given its cosine.
x = arccos(0.9) ≈ 25.8°
Angle x is about 25.8°.

20 POINTS * A circle has a radius of 6. An arc in this circle has a central angle of 48°
What is the length of the arc?
Either enter an exact answer in terms of it or use 3.14 for it and enter your answer as a decimal.
Answer:
[tex] \frac{8\pi}{5}[/tex]
Step-by-step explanation:
Since this is a degree we going to use the arc length formula
[tex]2\pi \times( r)( \frac{x}{360)} [/tex]
where x is the central angle measure and r is the radius.
The radius is 6 and the central angle is 48 so let plug that in the formula
[tex]2\pi \times (6)( \frac{48}{360} )[/tex]
Multiply 2 pi by 6
[tex]12\pi \times ( \frac{48}{360} )[/tex]
[tex]12\pi \times \frac{4}{30} [/tex]
[tex] \frac{12\pi}{1} \times \frac{4}{30} = \frac{48\pi}{30} [/tex]
[tex] \frac{8\pi}{5} [/tex]
