Based on the lengths of the segments in the ellipse below, how long is the major axis of the ellipse? Show your work.
Check the picture below.
the distances d1 and d2 are for this ellipse 7 and 3 respectively, keeping in mind that their sum is always the same, namely d1 + d2 is always the same 10 no matter where on the ellipse you move the point, notice in the picture, if we move d1 to the extent that lies flat right on top of d2, we have the length of d1 in purple, plus the length of d2, which we later colored in darkyellow, if we move d2 to the right-hand-side or the tail of d1, we'd end up with the ellipse's major axis, which is oddly enough, d1 + d2.
Work out the sizes of angles a, b and c. Give reasons for your answers.
Answer:
I think that you are wrong with that question
Answer:
a = 50° , b = 60° , c = 70°
Step-by-step explanation:
a and 130° are adjacent angles on a straight line and sum to 180° , then
a = 180° - 130° = 50°
b and 60° are vertically opposite angles and are congruent , so
b = 60°
the sum of the 3 angles in a triangle = 180° , that is
a + b + c = 180°
50° + 60° + c = 180°
110° + c = 180° ( subtract 110° from both sides )
c = 70°

Keisha's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 41 liters. What are the possible numbers of minutes Keisha could add water? Use t for the number of minutes. Write your answer as an inequality solved for t.
Answer:
7≥t
Step-by-step explanation:
The tank already has 13litres of water in it.
Keisha plans on increasing the quantity of the water to 41 litres. Hence,
41 litres - 13litres = 28litres
The above implies that she needed 28litres to be added to the fish tank.
She adds 4 litres per minute
Now, the question can now be reframed as how many minutes will be needed to add 28litre.
Considering to proportion method
4litres = 1 minute
28litres = t minutes
4litres × t minutes = 28litres
t = 28/4
t = 7 minutes
Hence, at least 7 minutes will be needed to increase the quantity of the tank water from 13litres to 41litres
But since we are to write the answer in an inequality form.
41≥ 13+4t
Solve for t
41≥13+4t
41-13≥4t
28≥4t
Divide both sides by 4
28/4≥4t/4
7≥t

A triangle has sides with lengths of 6 feet, 16 feet, and 17 feet. Is it a right triangle?
Answer:
No.
Step-by-step explanation:
This is not a right triangle. Use the Pythagorean Theorem, [tex]a^{2} + b^{2}=c^{2} \\[/tex], but write it as [tex]c^{2}= a^{2}+b^{2}[/tex]. The hypotenuse would be 17 feet, so you can insert 17 as [tex]c^{2}[/tex]. [tex]a[/tex] and [tex]b[/tex] could be 6 or 16. It can be written either way. The simplified equation would be:
[tex]c^{2}=a^{2} +b^{2} \\17^{2} = 6^{2} + 16^{2} \\17^{2} = 36+ 256\\17^{2}= 292\\289\neq 292[/tex]
This isn't a right triangle.

top of a flagpole to a hook in the
ground. The flagpole is 6 meters
high, and the hook is 8 meters
from its base. How long is the
rope?
Can someone help me pls!
Answer:
The length of the rope = 8.94 meters

The flagpole is 8 meters high
The hook is 4 meters from its base and the hook is in the ground
The flagpole and the ground ⊥ to each other
By using Pythagoras theorem:
The length of the rope = √(8² + 4²) = 5√5 = 8.94 meters

2x - 10 = 20
2x = 30

4x-10=2x+20(being alternate angle)
or,4x-2x=20+10
or,2x=30
or,x=30/2

Write the equation of the line that passes through the points (-6,6) and (7,7)
Answer:
y = 1/13 x + 84/13 or 13y = x + 84
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
= (7 - 6) / [(7 - (-6)]
= 1 / 13
Solve for b. Use (-6, 6)
y = mx + b
6 = 1/13 (-6) + b
6 = -6/13 + b
6 + 6/13 = b
84/13 = b
Substitute the m and b:
y = mx + b
y = 1/13 x + 84/13 or 13y = x + 84
