In ΔDEF, the measure of ∠F=90°, DF = 24, FE = 7, and ED = 25. What ratio represents the sine of ∠E?
===============================================================
Explanation:
Check out the drawing below.
The sine ratio involves opposite over hypotenuse, so we'll use sides DF and ED.
sin(angle) = opposite/hypotenuse
sin(E) = DF/ED
sin(E) = 24/25
The required measure of the sin of ∠E is given as sinE = 24 / 25.
In ΔDEF, the measure of ∠F=90°, DF = 24, FE = 7, and ED = 25. the ratio represents the sine of ∠E is to be determined.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.
Here,
The side perpendicular side opposite to the angle E is DF = 24,
Now.
Sin E = DF / ED
Sine E = 24 / 25
Thus, The required measure of the sin of ∠E is given as sinE = 24 / 25.

Which statements can be used to compare the characteristics of the functions? Select three options.
Answer:
Step-by-step explanation:
g(x) has the smallest minimum value. All three functions share the same domain and the y-intercept is also the same for all three thus options (C),(D), and (E) is correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
As per the given table,
The minimum value among all functions is -204 which is for g(x).
The domain is the set of x since all function defines the same x thus they have the same domain.
At y-intercept x = 0
Since at x = 0 all function is 3 thus all three will have the same y-intercept.
Hence "The smallest minimal value is for g(x). The y-intercept for all three functions is the same, and all three functions have the same domain".

in triangle JKL, angle JKL is a right angle, line KM is an altitude, JL=20, ML=4. Find KM
9514 1404 393
Answer:
KM = 8
Step-by-step explanation:
The ratio of long side to short side is the same for all of the triangles in this geometry:
KM/ML = JM/KM
KM² = ML·JM = 4(20-4) = 64
KM = √64 = 8
The length of KM is 8 units.

Which best describes the relationship between the line that passes through the points (-6, -1) and (-11, 1) and the line that passes thre
the points (-3, -8) and (-5, -13)?
Answer:
B. They are perpendicular
Step-by-step explanation:
calculate the gradient of (-6, -1) and (-11, 1)
m= y2 - y1/ x2 - x1
= 1 - (-1)/ -11 -(-6)
m = -2/5
then you find the gradient of the other points in the same way
m = y2 - y 1/ x2 -x1
= -13 -(-8)/ -5 -(-3)
m = 5/2
to prove that they are perpendicular
m1×m2 = -1
-2/5 × 5/2 = - 1
hence they are perpendicular

What's the length of QR?
A) 1
B) 17.7
C) 6.7
OD) 5
Answer:
5
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
QR^2 + 12^2 = 13^2
QR^2 +144 =169
QR^2 = 169-144
QR^2 =25
Take the square root of each side
QR = sqrt(25)
QR =5

Answers:
Domain = {0, 6, 7}
Range = {-8, 1, 7, 8}
======================================================
Explanation:
The domain is the set of allowed x inputs. So we simply list the x coordinates. Toss out any duplicates. Sorting the values is optional.
The range is the set of y coordinates. Like with the domain, we'll toss out any duplicates and optionally we can sort the y values.

9514 1404 393
Answer:
94.9
Step-by-step explanation:
It is straightforward addition to find the sum of the two numbers to be 94.871. Perhaps you're interested in rounding to the appropriate precision.
Here, the number with the fewest digits right of the decimal point is 10.9. In order to round the addition result appropriately, that "exact" result must be rounded so it has this same number of digits to the right of the decimal point (1 digit).
94.871 ≈ 94.9
_____
Additional comment
When you're asked to round a sum (or difference) to the appropriate precision, always first compute the exact result using the full precision of all contributors. Then determine the contributor with the least precision (least significant digit is farthest to the left), and round the result to that same precision.

Find the value of z.
A. 25.25
B. 76.25
C. 51
D. 129
Answer:
25.25
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
The angle formed by the two chords is (180 -x)
We need to find x first
x = 1/2 (54+204)
x = 129
The angle formed by the two chords is (180 -129) = 51
51 = 1/2 ( z+3z+1)
Multiply by 2
102 = 4z+1
101 = 4x
Divide by 4
101/4 = z
25.25 =z
