Answer:
it’s the 3rd one:)
Step-by-step explanation:
Answer:
In this situation, (h, k) = (-2, -3)Radius = 8/2 = 4 unitsSubstitute them into the circle equation: (x - h)² + (y - k)² = r²
(x - (-2))² + (y - (-3))² = 4²
(x + 2)² + (y + 3)² = 4²
Now expand the equation:
(x + 2)² + (y + 3)² = 4²
(x + 2)(x + 2) + (y + 3)(y + 3) = 16
(x² + 2x + 2x + 4) + (y² + 3y + 3y + 9) = 16
x² + 4x + 4 + y² + 6y + 9 = 16
x² + y² + 4x + 6y + 13 - 16 = 0
x² + y² + 4x + 6y - 3 = 0

Answer:
quiz score if no homework is done
Step-by-step explanation:
The y-intercept is the point where the horizontal coordinate is zero. That axis is defined as "hours per week spent on homework". So, the y-intercept is the function value when zero hours per week are spent on homework.
The function value is defined as "expected quiz score".
Then the y-intercept is ...
the expected quiz score when zero hours per week are spent on homework
If the ratio of x+y to x-y is 2/5, what's the ratio of y to x ?
9514 1404 393
Answer:
y/x = -3/7
Step-by-step explanation:
Write the given relationship and solve for y/x.
(x +y)/(x -y) = 2/5
5(x +y) = 2(x -y) . . . . . multiply by 5(x-y)
5x +5y = 2x -2y . . . . . eliminate parentheses
7y = -3x . . . . . . . . . . . add 2y-5x
y/x = -3/7 . . . . . . . . divide by 7x

Find the length of “c” using
the Pythagorean Theorem.
Enter
Answer:
13
Step-by-step explanation:
We know that a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = c^2
25+144 = c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)
13 =c
How to find the absolute value of |2b+4| with b=-8
Step-by-step explanation:
the absolute value simply removes a negative sign, if there is one. if there is no negative sign, it leaves the argument untouched.
so, we need to calculate the argument first :
2b + 4 = 2×-8 + 4 = -16 + 4 = -12
|-12| = 12
that's it.
Hernando's salary was $54,500 last year. This year his salary was cut to $52,355. Find the percent decrease. Round to the nearest tenth of a percent.
Answer:
Decrease by 3.9%
Step-by-step explanation:
54,500(1-x) = 52355
x=0.03935... = 3.935% or 3.9%
Answer:
first we subtract his new salary from the old salary to get the decrease.
Then percentage decrease ,we get the decrease over the new salary and multuply by 100. to get the percentage decrease

Which property of equality was used to solve this equation?
–5x=4
4
I=
OA.
addition property of equality
OB.
subtraction property of equality
OC. multiplication property of equality
OD
division property of equality
Answer:
D. division property of equality
Step-by-step explanation:
The division property of equality tell us basically to divide an equation, we have to divide on both sides.
-5x=4
to isolate x, we would divide -5 on both sides and that would be
-5x/5=4/-5
making x= -4/5, thus make D the correct answer choice

in digging a pipe trench that measures 29 feet long, 2 feet 9 inches wide, and 3 feet 6 inches deep.
How many cubic yards of earth were removed from the site?
Answer:
10.34
Step-by-step explanation:
converting digits to feet,
3ft 6in = 3.5 ft
2ft 9in = 2.75 ft
now feet to yards
3.5ft = 1.16666667 yards (rounded)
2.75ft = 0.9166666667 yards (rounded)
29ft = 9.66666667 yards (rounded)
multiplying them, you'll get approximately 10.34 cubic yards (rounded), that's the volume.
or you can multiply the digits in feet,
3.5×2.75×29
= 279.125 cubic ft
now to convert to cubic yards from cubic ft,
279.125/3³
= 10.337963..
= 10.34 (rounded to the nearest hundredth)

The outer radius of a cylindrical metal tube is R and t is the thickness of the metal. a Show that the volume, V. of metal in a length.7 units, of the tube is given by V. = m(2R - 0). b Hence calculate V when R = 7.5.1 = 1 and l= 20
Complete question is;
The outer radius of a cylindrical metal tube is R and t is the thickness of the metal.
A) Show that the volume, V, of metal in a length, l units, of the tube is given by V = πlt(2R - t)
B) Hence calculate V when R = 7.5. t = 1 and L = 20
Answer:
A)V = πlt(2R - t)
B)V = 879.65
Step-by-step explanation:
A) Formula for volume of a hollow cylinder is; V = π(R² - r²)h
Where;
R is outer radius
r is inner radius
h is height/length of tube
Now, we are told thickness is t.
Thus; R - r = t
Also, h = l
Thus;
V = π(R² - r²)h
Let's factorize this to get;
V = π((R + r)(R - r))l
V = π((R + r))lt
Since R - r = t
Then, r = R - t
Thus;
V = π(R + R - t)lt
V = πlt(2R - t)
B) when R = 7.5, t = 1 and l= 20;
V = πlt(2R - t)
V = π × 20 × 1(2(7.5) - 1)
V = 879.65
Solve the equation for all values of x.
(x2 – 16)(x2 + 49) = 0
Answer:
-4, 4, 7i, -7i
Step-by-step explanation:
Basically any or each bracket must be equal to 0. If x^2+16 = 0, then x can be 4 and -4, and if x^2+49 is 0, then x =7i or -7i
ASAP HELLP PLS, WILL GET BRAINLIEST FOR FIRST CORRECT ANSWER!!!
Diego says a quadrilateral with 4 congruent sides is always a regular polygon. Mai says it never is one.
Do you agree with either of them?
Answer:
A regular polygon all the angles, as well as all the sides, are equal.
Diego's claim is the quadrilateral with four congruent sides is always a regular polygon. He is only mentioning that the sides are equals.
He has not mentioned anything about the angles, the angles may or may not be equals.
In the case, if all the angles are equal too, then the claimed quadrilateral will be a regular polygon as shown in figure(a).
So, for this case, Diego's claim is correct while Mai's claim is also wrong.
While if all the angles are not equal, then the claimed quadrilateral will not be a regular polygon as shown in figure(b).
In this case, Diego's claim is wrong while Mai's claim is correct.
So, overall, considering both the case together, none of them have the correct claim.
So, both are wrong.

Answer:
115 in.^2
Step-by-step explanation:
The total surface area is the sum of the areas of the square base and the 4 congruent triangular faces.
SA = b^2 + 4 * bh/2
SA = (5 in.)^2 + 4 * (5 in.)(9 in.)/2
SA = 25 in.^2 + 2 * 45 in.^2
SA = 115 in.^2
Find the length of the third side. If necessary, write it in simplest radical form.
Answer:
a = sqrt(7)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2 +3^2 = 4^2
a^2 +9 = 16
a^2 = 16-9
a^2 = 7
Taking the square root
a = sqrt(7)
