Answer:
80degrees
Step-by-step explanation:
Using the expression to get the minor arc;
minor arc + major arc = 360degrees
minor arc + 260 = 360
minor arc = 360 - 260
minor arc = 100degrees (central angle)
Note that the central angle and that formed from the intersection of the tangents (X) are supplementary. Hence;
100 + X = 180
X = 180 - 100
X = 80degrees
What does 2x+4y=12 solve for?
Answer:
Hi, there for x it will be x=−2y+6
But if your solving for y it will be [tex]y=-\frac{1}{2}x+3[/tex]
Hope this Helps :)
Step-by-step explanation:
Let's solve for x.
2x+4y=12
Step 1: Add -4y to both sides.
2x+4y+−4y=12+−4y
2x=−4y+12
Step 2: Divide both sides by 2.
[tex]\frac{2x}{2}=\frac{-4y+12}{2}[/tex]
x=−2y+6
2.
Let's solve for y.
2x+4y=12
Step 1: Add -2x to both sides.
2x+4y+−2x=12+−2x
4y=−2x+12
Step 2: Divide both sides by 4
[tex]\frac{4y}{4} =\frac{-2x+12}{4}[/tex]
[tex]y=-\frac{1}{2} x+3[/tex]

Samantha places a mirror on the ground between herself and an apartment building and
stands so that when she looks into the mirror, she sees the top of the building. The center of
the mirror is 1.22 meters from her feet and 7.32 meters from the base of the building.
Samantha's eye is 1.82 meters above the ground. How tall is the building?
Answer:
The correct solution is "10.92 meters".
Step-by-step explanation:
The given values are:
Center of the mirror,
= 1.22 meters
Base,
= 7.32 meters
Samantha's eye,
= 1.82 meters
Let the height of the building will be "x".
Now,
The height of the building will be:
⇒ [tex]\frac{1.82}{x} =\frac{1.22}{7.32}[/tex]
By applying cross-multiplication, we get
⇒ [tex]x=\frac{1.82\times 7.32}{1.22}[/tex]
⇒ [tex]=\frac{13.322}{1.22}[/tex]
⇒ [tex]=10.92 \ meters[/tex]
I really need help with this problem
Answer:
Measure of angle K is 52.5 degrees
Step-by-step explanation:
Here, we have a case of two sides being congruent
mathematically when two sides are congruent, then we have an isosceles triangle
For an isosceles triangle, the base angles are equal
LM faces K , while M faces KL
What this mean is that L faces KM
From above, we can see that K = M = ?
Let us call this x
Mathematically, the sum of angles in a triangle is 180 degrees
75 + x + x = 180
2x = 180-75
2x = 105
x = 105/2
x = 52.5

Looking into the sky one night, Tori wondered how far into outer space she would get if she drove a car for 3.21 × 103 hours at a rate of 70mph. She calculated and determined that a car travelling at 70 mph covers approximately 1.13 × 105 meters per hour.
Tori wrote this expression to determine the distance she would travel into outer space.
(3.21 × 103)(1.13 × 105)
Estimate the distance travelled.

Given:
A right angle triangle with legs [tex]\sqrt{6}[/tex] cm and [tex]\sqrt{7}[/tex] cm. The length of the hypotenuse is x.
To find:
The value of x.
Solution:
Pythagoras theorem: In a right angle triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Using the Pythagoras theorem, we get
[tex]x^2=(\sqrt{7})^2+(\sqrt{6})^2[/tex]
[tex]x^2=7+6[/tex]
[tex]x^2=13[/tex]
Taking square root on both sides, we get
[tex]x=\sqrt{13}[/tex] [Because side length is always positive]
The measure of hypotenuse is [tex]\sqrt{13}[/tex] cm.
Therefore, the correct option is B.

Step-by-step explanation:
The general formula of quadratic equation is ax^2+bx+c.
easy question but need answer quick!!
Answer:
Step-by-step explanation:
Step 1: Find slope of Linear function A
[tex]slope = \frac{y_2 - y_1}{x_2-x_1} = \frac{-5--1}{-4--2} = \frac{-5 +1}{-4+2} = \frac{-4}{-2} = 2[/tex]
Step 2 : Find slope of B
Since they are perpendicular to each other, product of their slope = -1
That is,
[tex]m_A \times m_B = - 1\\2 \times m_B = -1\\\\slope, m_B = \frac{-1}{2}[/tex]
Given the function passes through (4, -6)
Equation of the linear function :
[tex]x_3 = 4 \ , \ y_3 = -6\\\\(y - y_3) = m_B (x - x_3)\\\\(y - -6) = -\frac{1}{2} (x - 4)\\\\y + 6 = -\frac{1}{2}x + 2\\\\y = -\frac{1}{2}x + 2 - 6 \\\\y = -\frac{1}{2}x -4[/tex]
Part B
Linear Function is parallel to B
Therefore the slope of B and slope of C are the same. And the equation will be of the form :
[tex]y = -\frac{1}{2} x + C[/tex]

The average time it takes to travel from home to school is 22 ½ minutes. Depending upon weather and morning traffic, the actual time on a given day can vary up to 5 ½ minutes.
Answer:
[tex]17 \le t \le 28[/tex]
Step-by-step explanation:
Given
[tex]t = 22\frac{1}{2}[/tex] --- average time
[tex]\triangle t = 5\frac{1}{2}[/tex] --- the variation
Required
The inequality to represent the scenario
To do this, we simply add and subtract the variation from the average time.
i.e.
[tex]t \± \triangle t[/tex]
So, the inequality is:
[tex]22\frac{1}{2} - 5\frac{1}{2} \le t \le 22\frac{1}{2} + 5\frac{1}{2}[/tex]
Solve:
[tex]17 \le t \le 28[/tex]

What is the multiplicative rate of change of the function?
2/3
3/4
4/3
3/2
Answer: 3/4
Step-by-step explanation:
Did the test
The required multiplicative rate in the given function is 3 / 4. Option B is correct.
The function which is in format f(x) =a^x where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
From the table of the exponential functions,
The multiplicative factor is given as,
K = y₂/y₁
K = [9 / 8] / [3/2]
K = 3 / 4
Thus, the required multiplicative rate in the given function is 3 / 4. Option B is correct.

Answer:
BC = 8 cm
Step-by-step explanation:
tan(x) = sin(x)/cos(x)
sin(x) is the opposite side of the angle x.
cos(x) is the side with a right angle to sin(x).
2 = 12/EC
EC = 12/2 = 6 cm
=>
CD = ED - EC = 10 - 6 = 4 cm
now, the same tan(x) relation had to be true for BCD.
tan(x) = BC/CD
2 = BC/4
BC = 8 cm
