Answer:
96 pi
Step-by-step explanation:
The formula for the volume of a cone is V=pi*r^2*h/3 the radius is 4 and the height is 18 plug in those values into the equation to get V=pi*16*6 16*=96 so the answer is 96 pi.
Volume = 96π cu. units
Step-by-step explanation:
Cone volume = πr^2h/3 where r = radius and h = height
V=π(4)^2(18)/3
V=π(16)(18)/3
V=π288/3
V=96π

Given the function g(x) = x^2 – 10x + 19, determine the average rate of change of
the function over the interval 3 < x < 6.
Answers
Answer:
- 1
Step-by-step explanation:
The average rate of change of g(x) in the close interval [ a, b ] is
[tex]\frac{g(b)-g(a)}{b-a}[/tex]
Here [ a, b ] = [ 3, 6 ] , then
g(b) = g(6) = 6² - 10(6) + 19 = 36 - 60 + 19 = - 5
g(a) = g(3) = 3² - 10(3) + 19 = 9 - 30 + 19 = - 2
average rate of change = [tex]\frac{-5-(-2)}{6-3}[/tex] = [tex]\frac{-5+2}{3}[/tex] = [tex]\frac{-3}{3}[/tex] = - 1

Observe that
7¹ ≡ 7 (mod 100)
7² ≡ 49 (mod 100)
7³ ≡ 343 ≡ 43 (mod 100)
and (using Euclid's algorithm)
7 ⁻¹ ≡ 43 (mod 100)
so that
7⁴ ≡ 7³ × 7¹ ≡ 43 × 7¹ ≡ 1 (mod 100)
This means
7⁷ ≡ 7⁴ × 7³ ≡ 1 × 43 ≡ 43 (mod 100)
Next,
(7⁷)⁷ ≡ 43⁷ ≡ (7 ⁻¹)⁷ ≡ (7⁷) ⁻¹ ≡ 43⁻¹ ≡ 7 (mod 100)

Next,
((7⁷)⁷)⁷ ≡ 7⁷ ≡ 43 (mod 100)
(4 7's)
A pattern emerges: a power tower involving an even number of 7's will reduce to 43 (mod 100), so the last two digits of ((7⁷)⁷ ... )⁷ with 2020 7's will have 43 as its last two digits.

Hi,
we need to substitute 4 and 1 in the equation, so for every y, we replace it with a 1 and every X with 4 as X= 4, Y = 1
equation: X + X (X + Y) + Y
equation after substituting the numbers: 1 + 1 (1 + 4) + 1
Bidmas rules apply.
expand the bracket first. 1 (1 + 4)=
1 X 1= 1
1 X 4= 4
1 + 4 = 5
then the equation becomes: 1 + 5 + 1= 7
your answer is 7 if you want to evaluate it.
your answer is 1 + 1 (1 + 4) + 1 if you need the equation.

Triangle GHI, with vertices G(4,-8), H(8,-9), and I(5,-6), is drawn inside a rectangle, as shown below ,What is the area, in square units, of triangle GHI?
Answers
Answer:
Hello,
Answer 9/2
Step-by-step explanation:
Let's put some points:
A=(4,-6)
B=(8,-6)
C=(4,-9) (the vertex of the rectangle)
AI=1, IB=3,AB=4
AG=2,GC=1
Area of the triangle AIG=1*2/2=1
Area of the triangle IBH=3*3/2=9/2
Area of the triangle GCH=1*4/2=2
Area of the rectangle=4*3=12
Area of the triangle IGH=12-1-9/2-2=9/2 (unit²)
The area, in square units, of triangle GHI will be 9/2 or 4.5 square units.
What is the area of the triangle?The vertices of the triangle are (x₁, y₁), (x₂, y₂), and (x₃, y₃). Then the area of the triangle will be given as,
Area = 1/2 |[(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)]|
We have
(x₁, y₁) ⇒ (4, -8)
(x₂, y₂) ⇒ (8, -9)
(x₃, y₃) ⇒ (5, -6)
Then the area will be calculated as,
Area = 1/2[{4 x (-9) + 8 x (-6) + 5 x (-8)} - {- 8 x 8 - 9 x 5 - 6 x 4}]
Area = 1/2 [(-124) – (-133)]
Area = 1/2 x [9]
Area = 9/2 square units

find the vertex of this parabola y=-2x ^2-4x-5
Answers
Answer:
(1, -13)
Brainliest, please!
Step-by-step explanation:
To find the x coordinate of the vertex, we use the formula, -b / 2a. In this problem, a = 2, and b = -4. c is -5, but we don't need to know it.
- -4 / 2(2) = 4 / 4 = 1
Vertex = (1, y)
Next, we plug 1 back into the parabola equation for x to solve for y.
y = -2(1)^2 - 4(1) -5
y = -2^2 - 4 - 5
y = -4 - 4 - 5
y = -8 - 5
y = - 13
Vertex = (1, -13)

Step-by-step explanation:
This is an arithmetic sequence with a common difference of 3500
The formula for an arithmetic sequence is
an = a1+d(n-1) where a1 is the first term and d is the common difference
an = 48000+ 3500(n-1)
We want n = 24
a24 = 48000+3500(24-1)

3^2 is 3x3 which is 9
Answer:
9
Step-by-step explanation:
The 2 located to the right and above the 3 is called an exponent. This exponent is how many times the number to its lower left is repeated and multiplied by. In this instant, 3 will be multiplied twice (symbolized by the number 2).
In other words:
3 × 3
The 3 is repeated twice because the exponent is 2. If the exponent were 3, it would look like:
3 × 3 × 3
So going back to the question, 3^2 is 3 × 3 which equals 9.

Find the area of triangle ABC.
Answer Options:
A. 18.52 units²
B. 12.16 units²
C. 15.14 units²
D. 31.27 units²
Answers
Answer:
Option C, 15.14 units²
Step-by-step explanation:
area of the triangle,
6.82×5.04×sin(61.73)/2
= 15.1365001284..
= 15.14 units² (rounded to the nearest tenth)
The required area of the irregular triangle is 15.14 unit². Option C is correct.
Given that,
A figure of the triangle is shown,
Side AB = a =6.82
Side BC = b = 5.04
Angles, ∠A = 45.03°, ∠B = 61.73°.
The triangle is a geometric shape which includes 3 sides and the sum of the interior angle should not be greater than 180°.
Altitude is perpendicular bisector to the side of the triangle from the opposite vertex of the triangle.
The area of the given triangle can be given as,
Area = 1/2 * a * b sinB
= 1/2 * 6.82 * 5.04 * sin61.73°
= 1/2 * 6.82 * 5.04 * 0.88
= 15.14 unit²
Thus, the required area of the irregular triangle is 15.14 units². Option c is correct.

- 2x + 61=-34
Answers
Answer:
(13.5,-46.5)
Step-by-step explanation:
Since equation 2 is missing y, then x is a constant
-2x + 61 = 34
-2x = 34 - 61
-2x = -27
x = 13.5
Then plug x into the 1st
5x + y = 21
5 * (13.5) + y = 21
67.5 + Y = 21
y = 21 - 67.5
y = -46.5
So the point satisfying both equations is (13.5,-46.5)

Answers
Answer:

Answer:
Linda gets 33 candies
Step-by-step explanation:
Let's call Linda's number of sweets x and make an equation for the total number of candies:
70 = 4+ x + x
Then simplify it:
70 = 4 + 2x
We then solve for x ( which is the number of candies Linda gets ):
70 - 4 = 4 + 2x - 4
66 = 2x
66 ÷ 2 = 2x ÷ 2
33 candies = x ( amount Linda gets )
