The angle measures in triangle ABC are (d) m∠A = 60°, m∠B = 30°, m∠C = 90°
How to determine the angle measures?The side lengths are given as:
AB = 12 inches
BC = 6√3 inches
CA = 6 inches
From the list of options, the angles are 30°, 60° and 90°, respectively.
In a triangle, the angle opposite the largest side is the largest angle and vice versa.
This means that:
∠C = 90° --- opposite AB
∠A = 60° --- opposite BC
∠B = 30° --- opposite CA
Hence, the angle measures in triangle ABC are (d) m∠A = 60°, m∠B = 30°, m∠C = 90°

[tex] \frac{6}{7} x = 2[/tex]
[tex]x = 2 \div \frac{6}{7} = 2 \times \frac{7}{6} = \frac{7}{3} = 2 \frac{1}{3} [/tex]
Answer:
[tex]2\frac{1}{3}[/tex]
Step-by-step explanation:
So this question is essentially asking how many 6/7s can fit into 2/1. Or in other words, what is 2 divided by 6/7. This gives you the equation: [tex]\frac{2}{1}\div\frac{6}{7}[/tex]. Whenever you're dividing by a fraction, you just keep the first fraction (don't change anything), change the operation (from division to multiplication) and "flip" the fraction so if you had the fraction a/b it's now b/a. This gives you the equation: [tex]\frac{2}{1}*\frac{7}{6}[/tex]. You can now just multiply the denominator and numerator. This gives you the fraction: [tex]\frac{2*7}{1*6}[/tex] which simplifies to [tex]\frac{14}{6}[/tex]. This can be further simplified by dividing both the numerator and denominator by 2. If you don't know why this keeps the original value think of it as multiplying the fraction by [tex]\frac{0.5}{0.5}[/tex] or [tex]\frac{\frac{1}{2}}{\frac{1}{2}}[/tex]. Which is technically multiplying the value by 1, so it should keep the original value, you're just simplifying the numerator and denominator. Simplifying it, gives you the fraction: [tex]\frac{7}{3}[/tex]. This can be a mixed fraction by splitting it up into two parts: [tex]\frac{6}{3}+\frac{1}{3}[/tex]. Which when added is the same thing, except the second side simplifies, and you get [tex]2\frac{1}{3}[/tex]
y=-2 what is the slope
Answer:
Slope = 0
Step-by-step explanation:
This is a HORIZONTAL line ....horizontal lines have slope = 0
VERTICAL lines like x =2 have UNDEFINED slope.
Answer:
m = 0
Step-by-step explanation:
This type of linear equation would be a horizontal line when graphed meaning that the slope would equal zero.
So in the equation y = -2, the slope is missing as the ' mx ' because it is horizontal.
A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:
f(n) = 10(1.02)n
Part A: When the scientist concluded his study, the height of the plant was approximately 11.04 cm. What is a reasonable domain to plot the growth function?
Part B: What does the y-intercept of the graph of the function f(n) represent?
Part C: What is the average rate of change of the function f(n) from n = 1 to n = 5, and what does it represent?
The average rate of change of the function from n = 1 to n = 5 is 3.36 plants per day
The reasonable domainThe function is given as:
f(n) = 10(1.02)^n
The maximum height is 11.04
So, we have:
10(1.02)^n = 11.04
Divide by 10
1.02^n = 1.104
Take the log of both sides
n * log(1.02) = log(1.104)
Divide by log(1.02)
n = 5
Hence, the reasonable domain is 0 ≤ n < 5
The y-interceptWe have:
f(n) = 10(1.02)^n
Set n to 0
f(0) = 10(1.02)^0
Evaluate
f(0) = 10
Hence, the y-intercept is 10
The average rate of changeWe have:
f(n) = 10(1.02)^n
Calculate f(1) and f(5)
f(1) = 10(1.02)^1 = 10.2
f(5) = 10(1.02)^5 = 10.2
The average rate is then calculated as:
m = (f(5) - f(1))/(5 - 1)
This gives
m =(11.04 - 10.2)(5 - 1)
Evaluate
m = 3.36
Hence, the average rate of change of the function f(n) from n = 1 to n = 5 is 3.36

Halla un numero que aumentado en 36 resulta el doble del numero , disminuido en 18 .
The number should be 54, where we can add 36 to get twice the number decreased by 18.
What is linear equation?There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation.
Given that, when we add 36 with a number then it gives twice the number decreased by 18.
Let the number be [tex]x[/tex] .
We get the linear equation
[tex]x+36=2x-18\\\Rightarrow x-2x=-18-36\\\Rightarrow -x=-54\\\Rightarrow x=54[/tex]

(5 * 3y + 5 * 2) + 6Then, just simplify
15y + 10 + 6Combine Like Terms
Now that all values are distributed like terms need to be added together.

Find the explicit equation that represents the following recursive equation:
t(1)=5
t(n+1)=8 multiply by t(n)
help :((
The explicit equation of the function is t(n) = 5 * 8^(n-1)
How to determine the explicit equation?The function definition is given as:
t(1)=5
t(n+1)=8t(n)
Let n = 1
So, we have:
t(2) = 8t(1)
Divide through by t(1)
t(2)/t(1) = 8
The common ratio of the function is:
r = t(2)/t(1) = 8
The explicit rule is then calculated as:
t(n) = t(1) * r^(n-1)
So, we have:
t(n) = 5 * 8^(n-1)

How to get the measure of angle BFE?
Notice that the measure of angle ∠BFE will be equal to:
∠BFE = ∠BFC + ∠CFD + ∠DFE
Where:
∠CFD = 90°
∠DFE = 30°
And we will have that:
∠AFC = 180° - 90° - 30° = 60°
And we know that BF bisects that angle, then:
∠BFC = 30°
So we conclude that:
∠BFE = ∠BFC + ∠CFD + ∠DFE = 30° + 90° + 30° = 150°

What is the distance between points M and N?
By using triangle properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.
How to determine the distance between two points
In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:
[tex]\cos L = \frac{(19.6\,m)^{2}-(14.8\,m)^{2}-(21.4\,m)^{2}}{-2\cdot (14.8\,m)\cdot (21.4\,m)}[/tex]
L ≈ 62.464°
Then, we get the distance between points M and N by the law of the cosine once again:
[tex]MN = \sqrt{(7.4\,m)^{2}+(10.7\,m)^{2}-2\cdot (7.4\,m)\cdot (10.7\,m)\cdot \cos 62.464^{\circ}}[/tex]
MN ≈ 9.8 m
