Answer:
d = 1406.25
Step-by-step explanation:
Given d is proportional to s² then the equation relating them is
d = ks² ← k is the constant of proportion
To find k use the condition d = 900 when s = 20
900 = k × 20² = 400k ( divide both sides by 400 )
2.25 = k
d = 2.25s² ← equation of proportion
When s = 25, then
d = 2.25 × 25² = 2.25 × 625 = 1406.25

Answer:
measure of Arc FJ is 80 degrees.
Step-by-step explanation:
Key skills: High School Geometry, One Variable Equations, Angles
1)Let's look at the diagram thoroughly
2) The 2 thing we can get are:
Angle HKG and Angle IKJ are vertical angles (which means they are congruent). Angle HKG + Angle GKF + Angle FKJ = 180 (Since they all form a straight angle - A straight angle is 180 degrees in measure.)3) First we can use the fact that Angle HKG and Angle IKJ are vertical angles. This makes them congruent (Or equal in size)
We can then solve for x by making the equation: 3x-22=x+104) Solve this by moving the x's to one side, and the numbers to the other. You would then get: 3x-x=10+22
3x-x= 2x 10+22=32
2x=32
Divide by 2 on both sides and x=16.
5) We get that x=16. Now to find the measure of Arc FJ, we need to use the fact that Angle HKG + Angle GKF + Angle FKJ = 180
What we want to find is Angle FKJ. The measure of Angle FKJ would be the measure of Arc FJ
6) We can make an equation: x+10+74+Angle FKJ=180
Solve this --> x=16, so substitute it in16 + 10 + 74 + Angle FKJ=180100 + Angle FKJ = 180Angle FKJ = 80 degreesIf Angle FKJ is 80 degrees, then Arc FJ measures 80 degrees.

Line q passes through the points (4, 6) and (0, 6). What is the equation for the line which is perpendicular to q and passes through the point (–2, 3)?
Answer:
x = -2Step-by-step explanation:
The slope of q:
[tex]m_q=\dfrac{6-6}{4-6}=0[/tex]
It means the line q is parallel to X-axis. Therefore any line perpendicular to q is parallel to Y-axis.
Any line parallel to Y-axis is: x = x₀, where x₀ is the x-coordinate of any point the line passing through.
(-2, 3) ⇒ x₀ = -2

The suns diameter if 10 times the diameter of jupiter. If jupiter is 11 times larger than earth, how much larger than earth is the sun
Given:
The suns diameter is 10 times the diameter of Jupiter.
Jupiter is 11 times larger than earth.
To find:
How much larger than earth is the sun?
Solution:
Let the diameter of earth be x.
Jupiter is 11 times larger than earth. So,
Diameter of the Jupiter = 11x
The suns diameter is 10 times the diameter of Jupiter. So,
Diameter of sun = 10(11x)
Diameter of sun = 110x
Since, diameter of earth is x and diameter of sun is 110x, therefore, diameter of sun is 110 times of the earth.
Hence, the sun is 110 times larger than earth.
The diameter of the sun is 110 times greater than the diameter of the earth.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The sun's diameter is 10 times the diameter of Jupiter. If Jupiter is 11 times larger than earth.
Let the diameter of the Sun, Jupiter, and Earth be S, J, and E respectively
Then we have
S = 10J ...1
J = 11 E ...2
From equations 1 and 2, we have
S = 10 × 11 E
S = 110 E

Help with this please. I’d appreciate if you showed the steps and the answer. Thanks!
Answer:
it‘s about
32.08 ft (if its not an answer choice try 32 or anywhere near that number)
Step-by-step explanation:
SO this is a simple example of triangles
We would need to find the heigh of the flagpole which is the leg of the triangle
The other side (14ft) is the 2nd leg of the triangle
And we know the hypotenuse is 35 ft
So we put that in Pythagorean Theroux and solve for the first missing leg
a^2+14^2=35^2
a^2+196=1225
a^2=1029
√1029 is about 32.08
So its about 32.08

Values in the question are missing ; we could get some input for the missing values and solve the question asked :
Jaclyn is training for a long bike ride. Right now, her longest ride is 36 miles. She plans to add 2 miles each week to her longest ride. Use a linear equation to determine the length of Jaclyn's longest ride after 6 weeks. Do not include units in your answer.
Answer:
48 miles
Step-by-step explanation:
Given that:
Longest ride (initial) = 36 miles
Additional miles per week = 2 miles
y(x) = mx + c
c = initial ride ; m = rate (increase in miles per week) ; x = number of miles per week
Longest ride after 6 weeks will be :
[Longest ride (initial) + additional miles per week * number of weeks]
Longest ride after 6 weeks :
36 miles + (2 * 6)
36 + 12
48 miles after 6 weeks

What is the product (4x)(-3x^6)(-7x^3
Answer:
the product of [tex](4x)(-3x^6)(-7x^3)[/tex] is [tex]\mathbf{84x^{10}}[/tex]
Step-by-step explanation:
We need to find the product of [tex](4x)(-3x^6)(-7x^3)[/tex]
For finding the product we will multiply coefficients separately and bases and their powers are multiplied separately.
[tex](4x)(-3x^6)(-7x^3)\\=4(-3)(-7)(x)(x^6)(x^3)\\[/tex]
Using the exponent law: [tex]a^m.a^n=a^{m+n}[/tex] ( When the bases are multiplied, their exponents are added)
[tex]=84x^{1+6+3}\\=84x^{10}[/tex]
So, the product of [tex](4x)(-3x^6)(-7x^3)[/tex] is [tex]\mathbf{84x^{10}}[/tex]
A drone has an effective range represented by a circle on a coordinate plane. The points (–12, 3) and (–6, –5) are endpoints of a diameter of this boundary. Which equation represents the effective range boundary for the drone?
(x + 96)^2 + (y + 1)^2 = 25
(x – 9)^2 + (y – 1)^2 = 25
(x + 9)^2 + (y + 1)^2 = 100
(x – 9)^2 + (y – 1)^2 = 100
Answer:
(x+9)^2 + (y+1)^2 = 100
Step-by-step explanation:
Since the question says diameter, we know the boundary in a circle. Therefore, we just need to find the center and radius.
The center is the midpoint of the two endpoints on a diameter.
Here, it is (-9, -1).
Therefore, the left part of the equation is (x- -9)^2 + (y - -1)^2 = (x+9)^2 + (y+1)^2.
The radius: sqrt(8^2 + 6^2) = 10
So the equation is (x+9)^2 + (y+1)^2 = 100
Answer:
A) (x + 9)^2 + (y + 1)^2 = 25

Step-by-step explanation:
The unit rate would be how many eggs one chicken lays
To do this, you would create a ratio
30:12 = x:1
30 = 12x cross multiply
30/12 = 12x/12 isolate the variable

1. What is the smallest decimal in hundredths rounded to 0.5?
Answer: 0.45!
Step-by-step explanation:
The smallest decimal in hundredths rounded to 0.5 is 0.45 and this can be determined by using the rules of rounding off to the nearest hundredths.
Given :
Number - 0.5
Rules for rounding off to the nearest hundredths are:
Rule 1 - When a number is rounded off to the nearest hundred remember that the digit at tens place is in between 0 to 4 then replace that digit by 0.
Rule 2 - When a number is rounded off to the nearest hundred remember that the digit at units place is greater than or equal to 5 then replaced tens place digit by 0 and hundreds place digit is increased by 1.
So, according to the rules, the smallest decimal in hundredths rounded to 0.5 is 0.45.
