Points D, E, and F are on circle C and EF ≅ DF.
Circle C is shown. Line segments D C and E C are radii. Point F is on the opposite side. Lines are drawn from points D and E to point F. Tangents D G and E G intersect at point G. Angle D G E is 76 degrees and angles G D C and G E C are 90 degrees. D F and E F are congruent.
What is the measure of ∠CDF?
14°
19°
26°
38°
Answer:
14°
Step-by-step explanation:
Angle DCE is congruent to Angle GDF
To find the measure of Angle CDF, you need to find the measure of Angle DCE first.
360° = 76° + 90° + Angle DCE + 90°
360° = 256° + Angle DCE
Angle DCE = 104°
Then you subtract 90° from 104° (Angle DCE) to get the measure of Angle CDF
104° - 90° = 14°
Angle CDF = 14°
Answer:
C. 26 degrees

E/P 14)The equation 2x²+ 4kx - 5k = 0, where k is a constant, has no real roots.
Prove that k satisfies the inequality -5/2<k<0.
Step-by-step explanation:
Discriminant = 16k² - 4(2)(-5k)
Since 16k² + 40k < 0, 2k² + 5k < 0, k(2k + 5) < 0.
Therefore -5/2 < k < 0.
Solve this inequality for x.

Shannon has already cycled 9 kilometers this year, plus she plans to cycle 1 kilometer during each trip to work. How many trips will Shannon have to make to cycle a total of 50 kilometers?
Answer:
Shannon has to make 41 trips to cycle a total of 50 kilometers.
Step-by-step explanation:
Given that
Shannon has cycled 9 kilometers this year
Let x be the number of trips that Shannon will make during the year
As she cycles 1km per trip, the total distance in trips will be: 1x
She has to cycle 50 kilometers in a year so the equation for this problem is:
[tex]9+x = 50[/tex]
Solving this equation will give us the number of trips she has to make
[tex]9+x = 50\\x = 50-9\\x = 41[/tex]
Hence,
Shannon has to make 41 trips to cycle a total of 50 kilometers.

Answer:
Fiona earns $2/hour more than Philip.
Step-by-step explanation:
y = 12x shows a slope of 12. That slope is the hourly salary.
Philip earns $12/hour.
Fiona:
$42/(3 hours) = $14/hour
Fiona earns $14/hour
14 - 12 = 2
Fiona earns $2/hour more than Philip.
help me pls!! thank you!!
(x-3)(x-8)=0 apply the zero product property
Answer:
x=3
x=8
Step-by-step explanation:
The "Zero Product Property" says:
If (x−3)(x−8) = 0 then (x−3) = 0 or (x−8) = 0
Now we just solve each of those:
For (x−3) = 0 we get x = 3
For (x−8) = 0 we get x = 8
And the solutions are:
x = 3, or x = 8

Help please!!!! if <1 <3 which conclusion can be made?
Answer:
B. c // d
Step-by-step explanation:
When ∠1 = ∠3, it means that they are corresponding angles and for that to be true, there must be a pair of parallel lines and one line to cut across both of the lines. Thus, we can conclude that c and d are the parallel lines and a is the line that cut across both of them, creating the corresponding angles.

prove that A(BC)=(AB)C as the associative law of matrix multiplication
Answer:
[tex]A\left(BC\right)=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]
[tex]\left(AB\right)C=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]
Therefore, we conclude that
[tex]A(BC)=(AB)C[/tex]
Step-by-step explanation:
Given that the associative law of matrix multiplication
[tex]A(BC)=(AB)C[/tex]
Let
[tex]A=\begin{pmatrix}1&2\\ 3&4\end{pmatrix}[/tex]
[tex]B\:=\:\begin{pmatrix}1&0\\ 1&2\end{pmatrix}[/tex]
[tex]C=\begin{pmatrix}1&3\\ \:1&1\end{pmatrix}[/tex]
proving
A(BC)=(AB)C
Determining the L.H.S
A(BC)[tex]A\left(BC\right)=\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}\:\left[\:\begin{pmatrix}1&0\\ \:\:\:1&2\end{pmatrix}\begin{pmatrix}1&3\\ \:\:\:\:1&1\end{pmatrix}\right]\:[/tex]
First determining BC
as multiplying the rows of the first matrix by the column of the second matrix
[tex]BC=\begin{pmatrix}1&0\\ \:1&2\end{pmatrix}\begin{pmatrix}1&3\\ \:1&1\end{pmatrix}=\begin{pmatrix}1\cdot \:\:1+0\cdot \:\:1&1\cdot \:\:3+0\cdot \:\:1\\ \:1\cdot \:\:1+2\cdot \:\:1&1\cdot \:\:3+2\cdot \:\:1\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}1&3\\ 3&5\end{pmatrix}[/tex]
so the matrix equation becomes
[tex]A\left(BC\right)=\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}\begin{pmatrix}1&3\\ \:3&5\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}1\cdot \:1+2\cdot \:3&1\cdot \:3+2\cdot \:5\\ 3\cdot \:1+4\cdot \:3&3\cdot \:3+4\cdot \:5\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}7&13\\ 15&29\end{pmatrix}[/tex]
[tex]A\left(BC\right)=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]

(AB)C[tex]\left(AB\right)C=\left[\begin{pmatrix}1&2\\ \:\:\:\:3&4\end{pmatrix}\:\begin{pmatrix}1&0\\ \:1&2\end{pmatrix}\right]\begin{pmatrix}1&3\\ \:\:\:\:\:1&1\end{pmatrix}\:[/tex]
First determining AB
as multiplying the rows of the first matrix by the column of the second matrix
[tex]AB=\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}\begin{pmatrix}1&0\\ \:\:1&2\end{pmatrix}=\begin{pmatrix}1\cdot \:\:1+2\cdot \:\:1&1\cdot \:\:0+2\cdot \:\:2\\ \:3\cdot \:\:1+4\cdot \:\:1&3\cdot \:\:0+4\cdot \:\:2\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}3&4\\ 7&8\end{pmatrix}[/tex]
so the matrix equation becomes
[tex]AB\left(C\right)=\begin{pmatrix}3&4\\ \:\:7&8\end{pmatrix}\begin{pmatrix}1&3\\ \:\:1&1\end{pmatrix}[/tex]
multiplying the rows of the first matrix by the column of the second matrix
[tex]=\begin{pmatrix}3\cdot \:1+4\cdot \:1&3\cdot \:3+4\cdot \:1\\ 7\cdot \:1+8\cdot \:1&7\cdot \:3+8\cdot \:1\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}7&13\\ 15&29\end{pmatrix}[/tex]
Thus,
[tex]\left(AB\right)C=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]
as
[tex]A\left(BC\right)=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]
[tex]\left(AB\right)C=\begin{pmatrix}7&13\\ \:15&29\end{pmatrix}[/tex]
Therefore, we conclude that
[tex]A(BC)=(AB)C[/tex]

The answers are: 2, 10, 50, 250
solve for x, -6x > 72
Answer:
x < -12
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define
-6x > 72
Step 2: Solve for x
Divide -6 on both sides: x < -12Here we see that any value x smaller than -12 would work as a solution to the inequality.
x is a natural number with
GCF(x, 36) = 9 and LCM(x, 36)
36) =108
Find x.
================================================
Work Shown:
x = some natural number
G = GCF(x,36)
L = LCM(x,36)
We can tie together the LCM and GCF like so
L = (x*36)/G
L = (x*36)/9
L = (36/9)*x
L = 4x
Whatever the value of x is, the LCM is 4 times larger.
Since we're told the LCM is 108, we can then say,
L = 108
4x = 108
x = 108/4
x = 27
--------------
Check:
GCF(x,36) = GCF(27,36) = 9, since 36 = 9*4 and 27 = 9*3, indicating that 9 is the largest shared factor
LCM(x,36) = LCM(27,36) = 108
LCM(x,36) = (x*36)/GCF = (x*36)/9 = (27*36)/9 = 972/9 = 108
This confirms we have the right answer.

The annual rainfall in a certain region is approximately normally distributed with mean 41.4 inches and standard deviation 5.7 inches. Round answers to the nearest tenth of a percent.
Complete question :
The annual rainfall in a certain region is approximately normally distributed with mean 41.4 inches and standard deviation 5.7 inches. Round answers to the nearest tenth of a percent. a) What percentage of years will have an annual rainfall of less than 43 inches? b) What percentage of years will have an annual rainfall of more than 39 inches? c) What percentage of years will have an annual rainfall of between 38 inches and 42 inches?
Answer:
0.61053
0.66314
0.26647
Step-by-step explanation:
Given that :
Mean (m) = 41.4 inches
Standard deviation (s) = 5.7 inches
a) What percentage of years will have an annual rainfall of less than 43 inches?
P(x < 43)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (43 - 41.4) / 5.7 = 0.2807017
p(Z < 0.2807) = 0.61053 ( Z probability calculator)
b) What percentage of years will have an annual rainfall of more than 39 inches? c)
P(x > 39)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (39 - 41.4) / 5.7 = −0.421052
p(Z > −0.421052) = 0.66314 ( Z probability calculator)
What percentage of years will have an annual rainfall of between 38 inches and 42 inches?
P(x < 38)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (38 - 41.4) / 5.7 = −0.596491
p(Z < −0.596491) = 0.27545 ( Z probability calculator)
P(x < 42)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (42 - 41.4) / 5.7 = 0.1052631
p(Z < 0.1052631) = 0.54192 ( Z probability calculator)
0.54192 - 0.27545 = 0.26647
Are all even numbers composite prove it
all even numbers are composite except for 2
A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. ... Therefore all numbers that end with five and are greater than five are composite numbers.
