Answer:
x^2 + 16x - 15 = 0.
Step-by-step explanation:
x^2 + 16x – 11 = 4 Subtract 4 from both sides:
x^2 + 16x - 15 = 0 is one equation with the same roots.
Also any equation which is a multiple of the above will have the same roots. For example if we multiply by 3:
3x^2 + 48x - 45 = 0.
solve the equation-4(x+10)-6=-3(x-2)
Answer: x= -52

In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.
Answer:
13.96
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Given
m<HJK = 50
HJ = 16units
Required
length of arc HK
arc HK = 50/360 * 2(3.14)(16)
arc HK = 5/36 * 100.48
arc HK = 502.4/36
arcHK = 13.96
hence the length of arcHK to nearest hundredth is 13.96
State if the two triangles are congruent. If they are, state how you know
A) SSS
C) ASA
B) Not congruent
D) SAS
Answer:
C) ASA
Step-by-step explanation:
angles are indicated equal and they share the common diagonal between those angles, so ASA
The given two triangles are congruent due to the ASA postulate, which is the correct answer that would be an option (C).
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
The given triangles are given in the figure.
We can see that there are two angles that are the same and one side is the same.
According to ASA, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.
So, we conclude that the given two triangles are congruent.
Hence, the given two triangles are congruent due to the ASA postulate.

"La suma de la medida de los ángulos interiores de cualquier triángulo, es igual a dos triángulos rectos, o sea a 180°."
Answer:
Efectivamente, la suma de la medida de los ángulos internos de cualquier figura triangular es igual a 180º. Ahora bien, la oración posee un error de redacción, pues tanto los triángulos rectos como los equiláteros o los isósceles poseen dicha característica, es decir, no es únicamente una característica de los triángulos rectos. Además, la suma de los ángulos interiores de dos triángulos rectos sería igual a 360º, no a 180º.

Find the exact values of csc and sec
Answer:
cosec theta = 5/4
sec theta = 5/3
Step-by-step explanation:
Given that;
cot θ = 3/4
1/tanθ = 3/4
tanθ = 4/3
since tanθ = opp/adj
opp = 4
adj = 3
hyp^2 = 4^2 + 3^2
hyp^2 = 16+9
hyp^2 = 25
hyp = √25
hyp = 5
sin theta= opp/hyp
sin theta = 4/5
cosec theta = 1/sin theta
cosec theta = 1/(4/5)
cosec theta = 5/4
Get sec theta;
sec theta = 1/costheta
sec theta = 1/(3/5)
sec theta = 5/3

Answer:
9
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 9 when x = - 3
9 = - 3k ( divide both sides by - 3 )
- 3 = k
y = - 3x ← equation of variation
When y = - 27 , then
- 27 = - 3x ( divide both sides by - 3 )
9 = x

X^2-3x=7/4
Solve by completing the square
Answer:
Step-by-step explanation:
X^2-3x=7/4 should first be rewritten in standard form, which here would be:
x^2 - 3x - 7/4 = 0.
1. Identify the coefficient of the x term and take half of that number:
-3/2
2. square this result: (-3/2)^2 = 9/4
3. add this last result, 9/4, between the -3x term and the -7/4 term, and then subtract it as shown:
x^2 - 3x + 9/4 - 9/4 - 7/4 = 0
4. Rewriting the first 3 terms as the square of a binomial, we get:
(x - 3/2)^2 - 16/4 = 0, or (x - 3/2)^2 = 16/4
5. Take the square root of both sides, obtaining:
x - 3/2 = ±√4/2 or ±√2
6. Write out the two roots: x = 3/2 + √2
and x = 3/2 - √2
Using the graph below, calculate the average rate of change for f(x) from
x = 0 to x =2
1) -4
2) -2
3) 2
4) 4
Answer:
4
Step-by-step explanation:
Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
a = 0,
f(a) = f(0) = -2 (from the graph given)
b = 2,
f(b) = f(2) = 5 (from the graph)
Plug in the values
Average rate of change = [tex] \frac{5 - (-2)}{2 - 0} [/tex]
[tex] = \frac{7}{2} [/tex]
= 3.5 ≈ 4 (approximated)

Henri buys 126 inches of a fabric that costs $12 for each yard. How much dos Henri pay for the fabric
Answer: $47.28
Step-by-step explanation:
There are 126 inches of fabric.
You need to convert this to yard as that is the pricing unit.
1 yard = 36 inches
126 inches is:
= 126/32
= 3.94 yards
Cost is $12 per yard so Henry pays:
= 12 * 3.94
= $47.28

If the measure of arc AD is 65 degrees and the measure of arc BC is 45 degrees, what is the measure of angle BEC?
Answer:
[tex]\angle BEC=55 \textdegree)[/tex]
Step-by-step explanation:
From the question we are told that:
Arc [tex]AD =65 \textdegree[/tex]
Arc [tex]BC =45 \textdegree[/tex]
Given The angle of intersecting chords theorem
Generally the equation for angle BEC is mathematically given by
[tex]\angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)[/tex]
[tex]\angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)[/tex]
[tex]\angle BEC=55 \textdegree)[/tex]

Every two out of three kids sang at the talent show. What percent of the kids did not sing at the talent show? (round)
33.3% do not sing in the talent show.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of kids = 3
Number of kids who sang = 2
The number of kids who do not sing.
= 3 - 2
= 1
The percentage of kids who do not sing.
= 1/3 x 100
= 33.33%
Thus,
33.3% do not sing in the talent show.
