write an equation for each line in slope-intercept form
Quick Help Please
anyone
Answer:
1) False
2) True
3) a) True b) False
4) False
Step-by-step explanation:
1)
Two-point are collinear if they lie in the same line. The vector -2AB is antiparallel to the vector AB then it is False.
2)
A unit vector could be difinede as:
[tex]\vec{u}=\frac{\vec{v}}{|\vec{v}|}[/tex]
Terefore, [tex]\frac{1}{AB}\vec{AB}[/tex] is a unit vector. It is True.
3)
a) If AB=-3AC
The points, A, B, and C are collinear, because all of them lie in the same line. True
b) Let's take the modulus in each side.
[tex]\vec{AB}=-3\vec{AC}[/tex]
[tex]|\vec{AB}|=|-3\vec{AC}|[/tex]
[tex]|\vec{AB}|=|-3||\vec{AC}|[/tex]
[tex]|\vec{AB}|=3|\vec{AC}|[/tex]
So it is False.
4)
If we put the vector AI = 3/2 AB into the first equation we will have:
[tex]2(-\frac{3}{2}\vec{AB})+3\vec{IB}=-3\vec{AB}+3\vec{IB}[/tex]
And we can not say that it is a cero vector, so it is False.
I hope it helps you!
HELP ASAP GEOMETRY 10th
Answer:
m<FEG = 23°
m<FEH = 113°
Step-by-step explanation:
A diameter is always 180° to it's corresponding arc.
The circumference or full arc of a circle is 360°.
If EG is a diameter, Arc EG is 180°.
Given that Arc EF = 134°, and Arc EG = 180°.
Arc EF + Arc EG + Arc FG = 360°.
134° + 180° + Arc FG = 360°
314° + Arc FG = 360°
–314° –314°
Arc FG = 360° – 314° = 46°
The angle formed by the two chords that make the arc is ½ the measure of that Arc.
Meaning that m<feg which is the angle formed by arc FG is ½ 46° which means that m<feg = 23°.
Given that segment EH is tangent to point E.
The rule of a segment and a tangent is that the angle formed is also ½ the measure of the arc.
This means that m<FEH = ½(Arc FG + Arc EG)
m<FEH = ½(46° + 180°) = ½(226°) = 113°

What is the distance between points G and B
Answer:
4
Step-by-step explanation:
Since points B and G are both on the same horizontal line, the distance between them is just the horizontal distance between them which is the absolute value of the difference of their x-coordinates.
distance = |-3 - 1| = |-4| = 4
Answer: 4

Cyclone cleared leaves from the same number of yards each day for 5 days. Then on day 6, he cleared the leaves from 8 more yards. He cleared 133 yards in all.
How many yards did Cyclone clear the first day?
Answer:
20.83 yard
Step-by-step explanation:
Calculate Cubic Yards
Calculate your area
Calculate your volume: Multiply area times the depth to get volume in cubic feet
Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer
Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard
Total yards = 5[x] + x + 8
Solve
133 = 6x + 8
6x = 125
x = 20.83 yard
Therefore, the Cyclone cleared 20.83 yards on the first day.

The real statue of liberty is 152 feet tall. If you wanted to build a toy model of the statue to sell to tourists that is 2:101 Scale factor, how tall should your model be?
Answer:
Height of toy model liberty statue = 3 feet (Approx.)
Step-by-step explanation:
Given:
Height of real liberty statue = 152 feet
Scale factor = 2:101
Find:
Height of toy model liberty statue
Computation:
Scale factor = 2:101
1 feet toy model = 101 / 2 = 50.5 feet
Height of toy model liberty statue = Height of real liberty statue / Scale factor
Height of toy model liberty statue = 152 / 50.5
Height of toy model liberty statue = 3 feet (Approx.)

Answer:
e = 31
Step-by-step explanation:
The triangle on the left has 2 congruent sides , so is isosceles with 2 congruent base angles of size
[tex]\frac{180-56}{2}[/tex] = [tex]\frac{124}{2}[/tex] = 62
Then the interior angle of the triangle on the right is
180° - 62° = 118°
The triangle on the right is also isosceles with 2 congruent base angles, then
e = [tex]\frac{180-118}{2}[/tex] = [tex]\frac{62}{2}[/tex] = 31

Write an equation of the line with the given slope and y-intercept
slope: 1.4, y-intercept: 5.6
O y = 1.4x + 5.6
Oy=-*x+5.6
O y = 1.4x -5.6
O y=-1.4x + 5.6
Someone help?
Answer:
y = 1.4x + 5.6
Step-by-step explanation:
plug the slope and y-intercept into the formula: y = ax + b (a is the slope and b is the y-intercept)
thus, y = 1.4x + 5.6
what of the following us a solution to the system of equations
Answer:
(- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 2 → (1)
6 + y = - x → (2)
Substitute y = 3x - 2 into (2)
6 + 3x - 2 = - x
4 + 3x = - x ( add x to both sides )
4 + 4x = 0 ( subtract 4 from both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = 3(- 1) - 2 = - 3 - 2 = - 5
solution is (- 1, - 5 )

Sasha's grandma is going to sew this umbrella for Sasha. The umbrella is made of 4 identical triangles. If each triangle is 3 feet long and 4 feet high, how many square feet of fabric does Sasha's grandma need? Explain how you found your answer.
Answer:
Sasha's grandma will need 48 square feet of fabric to sew the umbrella.
Step-by-step explanation:
Since Sasha's grandma is going to sew an umbrella for Sasha, which will be made of 4 identical triangles, if each triangle is 3 feet long and 4 feet high, to determine how many square feet of fabric does Sasha's grandma need, the following calculation must be done:
(3 x 4) x 4 = X
12 x 4 = X
48 = X
Therefore, Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

You are watching fireworks over San Diego Bay S as you sail away in a boat. The highest point the fireworks reach F is about 0.2 mile above the bay. Your eyes E are about 0.01 mile above the water, the lowest elevation from which you see the fireworks above your horizon. (At point B you cannot see the fireworks because of the curvature of Earth.) The radius of Earth is about 4000 miles, and FE¯¯¯¯¯¯¯¯ is tangent to Earth at point T. Find mSB⌢. Round your answer to the nearest tenth.
Based on the calculations, the measure of angle m<SB rounded to the nearest tenth is equal to 0.70°.
What is a tangent?In geometry, a tangent is also referred to as a tangent line and it can be defined as a straight line that touches a plane curve at a specific point.
Based on the diagram, we would apply the cosine function to determine the measure of the angle formed by the hypotenuse side of the triangle with respect to the radius of Earth (adjacent side):
m<SB = cos⁻¹(4000/4000 + 0.2) + cos⁻¹(4000/4000 + 0.01)
m<SB = cos⁻¹(4000/4000.2) + cos⁻¹(4000/4000.01)
m<SB = cos⁻¹(0.99995) + cos⁻¹(0.9999975)
m<SB = 0.573 + 0.128
m<SB = 0.701 ≈ 0.70°.
