74
90
16
32
Answer:
Your answer is the second option; Option B; 90.
So, m∠2 is a right triangle, due to lines CE, and FD being perpendicular. Right Triangles are always 90.
In Zoie's class, 7/10 of the students walk to school. Another 1/5 of the students ride their bikes. The other students ride on the school bus. What fraction of the class rides on the school bus?
Answer:
ion know
Step-by-step explanation:
7/10 + 1/5 =
7/10 + 2/10 (1/5 x 2 = 2/10) = 9/10
10/10 - 9/10 = 1/10
therefore, 1/10 of the class rides on the school bus.

Find the measure of the arc or angle indicated.
Short Answer: arc LM = 110°
Comment
Any two angles that have their end points on the same end points as a chord and both moving away in the same direction (in this case down ) are equal. This is a fundamental fact about circles.
Equation
2x + 55 = x + 55
the only way this is going to make any sense is if x = 0. No other value is possible because it will destroy the equality.
Conclusion
Both angles = 55
But that's not what you are asked for.
What you are asked for
You want to know the measure of arc LM.
The angle connecting the center of the circle with its two arms running through the end points of the chord = the measure of arc LM
Draw a dot where the center of the circle is and call it O. Draw in <MOL
<MOL = 2* either of the 55° = 2 (<LKM) = 2 * 55 = 110° That's a property of the central angle.
The measure of arc LM = 110°

what is the domain of f (x) = 4 + 2x on a graph when the range is (0,6)
Answer:
(-2, 1).
Step-by-step explanation:
When f(x) = 0
4 + 2x = 0
2x = -4
x = -2.
Ehen f(x) = 6
4 + 2x = 6
2x = 6-4 = 2
x = 1.

Find the area of half a circle with a radius of 8cm
Answer:
P.S when it says OVER it me like a fraction
and PLZ MARK ME BRAINLY
Step-by-step explanation:
Consider a circle of radius 8 centimetres. Recall that the centre angle in a circle is always 360˚ . However, a semi-circle is a circle cut in half. Hence, the centre angle for the semi-circle is cut in half, or has a measure of 180˚
Here's a diagram of what's going on.
Before applying the formula, let's convert 180˚ to radians.
180˚ over 1 times π over 180°
We will now use the formula to determine the area of this semi-circle.
A= 1/2 × π × 8²
A=1/2 × π × 64
A= 32πcm²
We can confirm this using the formula for area of a semi-circle, A= r²π over 2
A= 8²π over 2
A= 32πcm²
Same, so both formulae work.

An industrial machine produces widgets, but it has a 0.07 detective rate. What is the probability that the machine produces fewer than 5 detective widgets in a production run of 100 items?
Answer:
0.22
Step-by-step explanation:
defective rate is 7 out of 100
defective rate of 4, or 3, or 2, or 1 defective is:
7/100 + 6/99 + 5/98 + 4/97 ≈ 22/100
The required probability for fewer than 5 defective rate is 0.10
An industrial machine produces widgets, but it has a 0.07 defective rate.
What is the probability?
Probability, can be define as the ratio of favorable events to the n number of total events.
defective rate fewer than 5
p of 4 defective + p for 3 defective+ p for 2 defective + p for 1 defective.
total p = 4/100 + 3/99 + 2/98 + 1/97 ≈ 0.10
Thus, The required probability for fewer than 5 defective rate is 0.10

Answer:
[tex](3)\ y = -x[/tex]
[tex](5)\ y = -3x -2[/tex]
Step-by-step explanation:
Required
The equation in slope intercept form
Solving (3):
[tex]m = -1[/tex]
[tex](x_1,y_1) =(4,-4)[/tex]
The equation in slope intercept form is:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = -1(x - 4) -4[/tex]
Expand
[tex]y = -x + 4 -4[/tex]
[tex]y = -x[/tex]
Solving (5):
[tex]m = -3[/tex]
[tex](x_1,y_1) = (1,-5)[/tex]
The equation in slope intercept form is:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = -3(x - 1) - 5[/tex]
Expand
[tex]y = -3x + 3 - 5[/tex]
[tex]y = -3x -2[/tex]

What is the value of y in the equation 4y-2(1-y)=-44?
Hi there!
[tex]\large\boxed{y = -7}[/tex]
4y - 2(1 - y) = -44
Begin by distributing -2:
4y - 2(1) - 2(-y) = -44
Simplify. A negative times a negative equals positive.
4y - 2 + 2y = -44
Combine like terms:
6y - 2 = -44
Add 2 to both sides:
6y = -42
Divide both sides by 6:
y = -7

Answer:
B.) 3x=15
Step-by-step explanation:
This is because you multiply 3 by x and if x=5 then it would be 3x5 thus resulting in 15
1) Plug 5 into all the spots for x. See if it makes the equation true.
A. 2+5 = 3 Nope
B. 3(5) = 15 Yep
C. 5/2 = 10 Nuh-uh
D. 5-7 = 12 Nah
B is the answer :)
I'm not sure if you need the answer to #2 but I'll answer it anyway. :)
2) An equation has to have a solution. This means it has an equal sign. C is the only one that has an equal sign.

Silas claims that the equation y=2+mx, where m is a real number, represents a function whose graph is a straight line.
Select the statement that BEST classifies this claim.
Answer:
The claim is true for all values of m.
Step-by-step explanation:
Given
[tex]y = 2 + mx[/tex]

The moon is a sphere with radius of 959 km. Determine an equation for the ellipse if the distance of the satellite from the surface of the moon varies from 357 km to 710 km. x squared divided by 357 plus y squared divided by 710 equals 1 x squared divided by 1669 squared plus y squared divided by 1316 squared equals 1 x squared divided by 1316 squared plus y squared divided by 1669 squared equals 1 x squared divided by 710 plus y squared divided by 357 equals 1
Answer:
[tex]\frac{x^2}{1316^2}+\frac{y^2}{1669^2}=1[/tex]
Step-by-step explanation:
An ellipse is the locus of a point such that its distances from two fixed points, called foci, have a sum that is equal to a positive constant.
The equation of an ellipse with a center at the origin and the x axis as the minor axis is given by:
[tex]\frac{x^2}{b^2}+\frac{y^2}{a^2} =1 \\\\where\ a>b[/tex]
Since the distance of the satellite from the surface of the moon varies from 357 km to 710 km, hence:
b = 357 km + 959 km = 1316 km
a = 710 km + 959 km = 1669 km
Therefore the equation of the ellipse is:
[tex]\frac{x^2}{1316^2}+\frac{y^2}{1669^2}=1[/tex]
#5: The population of a certain animal species decreases at a rate of 2.5%. If there are 400 of this animal in the wild, using an exponential function, predict approximately how many there will be in 4 years. Round to the nearest whole number. *
Answer:
There will be 361 individuals in 4 years.
Step-by-step explanation:
Exponential equation of population decay:
The amount of individuals of a certain population, after t years, with a decay rate of r(as a decimal), is given by:
[tex]A(t) = A(0)(1-r)^t[/tex]
In which A(0) is the initial population and r is the decay rate.
The population of a certain animal species decreases at a rate of 2.5%.
This means that [tex]r = 0.025[/tex]
There are 400 individuals:
This means that [tex]n = 400[/tex]. So
[tex]A(t) = A(0)(1-r)^t[/tex]
[tex]A(t) = 400(1-0.025)^t[/tex]
[tex]A(t) = 400(0.975)^t[/tex]
How many there will be in 4 years?
This is A(4). So
[tex]A(4) = 400(0.975)^4 = 361.4[/tex]
Rounding to the nearest whole number, there will be 361 individuals in 4 years.

Answer: [tex]10\left(\cos90^{\circ}+i\sin90^{\circ}\right)[/tex]
Step-by-step explanation:
Given
The complex number is [tex]z_1=0+10i[/tex]
Complex number in polar form is given by
[tex]z=r\left(\cos \theta +i\sin \theta\right)[/tex]
Compare it with the given complex number
[tex]r=10[/tex] and [tex]\sin \theta=1[/tex] which implies [tex]\theta[/tex] must be [tex]90^{\circ}[/tex]
So, in the polar form, it is
