Answer:
4. b
5. a
Step-by-step explanation:
4. The radius is the distance between the center (-6, -8) and the point on the circle (0, 0). The square of that is given by ...
r^2 = (-6-0)^2 +(-8-0)^2 = 36 +64 = 100
Only one of the offered choices has an r^2 value of 100: Choice B.
__
5. The center and the point are on the same line (y=9), so the radius is the difference of x-coordinates: r = 5-2 = 3. The center is given as (h, k) = (5, 9).
The form of the equation of a circle is ...
(x -h)^2 +(y -k)^2 = r^2
Filling in the given values, the equation is ...
(x -5)^2 +(y -9)^2 = 9 . . . . matches choice A

Exponential Functions and Equations
Answer:
by now you should have the answer right?
Step-by-step explanation:
Please Help Me...
Find The a9 to each sequence.
an=-2(-5)n-1
an=6(-3)n-1
an=-7 n-1
These are Geometeic Sequences and It's asking for the a9, which I believe is the 9th term for all of them step by step.
Answer:
Fore an=-2(-5)n-1
:substitutute 9 in place of "n" in the equation
= -2(-5)9-1
Multiply -2 and -5 to get positive 10
=(10)(9)-1
Multiply 10 and 9 to get 90
=90-1
Subtract 1 from 90
=89 therefore 9th term is 89
Step-by-step explanation:
For
an= 6(-3)n-1
(Follow the above procedure)
=6(-3)9-1
=-18-1
=-19
For
an= -7n-1
(Follow the same procedure as above)
-7(9)-1
=-63-1
=- 64

Answer:
x = 24
Step-by-step explanation:
3X +5 +2x-4 +2x +11 = 180
7x +12 = 180
7x = 180 - 12
7x = 168
7x/7 = 168/7
x =24

Answer:
Box-4 → (+)
Step-by-step explanation:
To find the value in the 4th box, we will expand the given logarithmic expression.
log₄x⁵y³ = log₄x⁵ + log₄y³
= 5log₄x + 3log₄y
Therefore, each box will have the values as,
Box-1 → 5
Box-2 → log₄
Box-3 → x
Box-4 → (+)
Box-5 → 3
Box-6 → log₄
Box-7 → y
There is the (+) sign in Box-4.

Answer:
C: 3^0 = 1
Step-by-step explanation:
When dividing two exponents with the same bases, you subtract them
2-2 = 0
so: 3^0 which equals 1

Enter
Answer:
a= 10.8 c=4.3
Step-by-step explanation:
Use the law of sines.
a/sin 120=8/sin 40
Which simplifies to: 8*sin (120)/sin (40)
When you put the equation into a calculator, it will answer with 10.77
Therefore, it will be 10.8 if round to the nearest tenth
Using the same concept of the answer to a, the equation will be:
10.8*sin 20/sin 120=4.26
Round to the nearest tenth, and c equals to 4.3
