Answer:
Th correct option is D. 13
Therefore the value of x is 13.
Step-by-step explanation:
Given:
measure of an intercepted arc = 86°
Center Angle = 86°
measure of the inscribed angle creating the intercepted arc= (3x+4)°
Angle Inscribed in arc = (3x+4)°
To Find:
value of x = ?
Solution:
Inscribed Angle Theorem:
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Substituting the values we get
Therefore the value of x is 13.
Answer:
B. 45 degrees
Step-by-step explanation:
We know that the square at the bottom corner means it's 90 degrees. Since there are 180 degrees in a triangle, we could do 180 - 90. Assuming it's perfectly symmetrical, we would divide 90 ÷ 2. This means that the angle measures 45 degrees.
Answer:
136
Step-by-step explanation:
h(x)=4(5x-1)
substitute 7 for x
h(7)=4(5(7)-1)
*****Remember PEMDAS*****
=4(35-1)
=4(34)
h(7)=136

<u>Recursive Formula for Arithmetic Sequences</u>
- <u />
- represents the nth term
- represents the preceding term
- represents the common difference
<u>Explicit Formula for Arithmetic Sequences</u>
- <u />
- represents the nth term
- represents the 1st term
- represents the common difference
<u>Ernest's Schedule Recursive Formula</u>
We can see that the common difference is because for each week, Ernest swims 0.25 more kilometers than the preceding one. Therefore, the recursive formula for Ernest is
<u>Ernest's Schedule Explicit Formula</u>
Given our common difference from earlier and the fact that is our first term, the explicit formula for Ernest is
<u />
<u>Denise's Schedule Recursive Formula</u>
We can see that the common difference is because for each week, Denise swims 0.5 more kilometers than the preceding one. Therefore, the recursive formula for Denise is
<u>Denise's Schedule Explicit Formula</u>
Given our common difference from earlier and the fact that is our first term, the explicit formula for Denise is
