Answer 1
Answer:

Answer:

Ok, If you are trying to solve for x then your answer in fraction form is x=4/11. If you want it in decimal form the answer is 0.36(Repeats forever). And these answers are also implying that when you typed a  "^" it meant multiplcation

Use log b 2=0.693 and /or log b 7 = 1.946
to find log b 14

Answers

We\ know:log_a(b\cdot c)=log_ab+log_ac\n\ntherefore:\n\nlog_b14=log_b(2\cdot7)=log_b2+log_b7=0.693+1.946=2.639

Which point lies on a circle that is centered at A(-3, 2) and passes through B(1, 3)?C(-1, -2)

D(-6, 3)

E(-3, -3)

F(-2, 6)

Answers

The equation of a circle:
(x-h)^2+(y-k)^2=r^2
(h,k) - the coordinates of the center
r - the radius

\hbox{the center: } A(-3,2) \nh=-3 \n k=2 \n \n\hbox{the equation:} \n(x+3)^2+(y-2)^2=r^2 \n \n\hbox{the circle passes through B(1,3)} \nx=1 \n y=3 \n \Downarrow \n(1+3)^2+(3-2)^2=r^2 \n4^2+1^2=r^2 \n16+1=r^2 \n17=r^2 \n \n\hbox{the equation is:} \n(x+3)^2+(y-2)^2=17

Plug the coordinates of the points into the equation and check:
C(-1,-2) \n(-1+3)^2+(-2-2)^2=17 \n2^2+(-4)^2=17 \n4+16=17 \n20=17 \nnot \ true \n \nD(-6,3) \n(-6+3)^2+(3-2)^2=17 \n(-3)^2+1^2=17 \n9+1=17 \n10=17 \nnot \ true

E(-3,-3) \n(-3+3)^2+(-3-2)^2=17 \n0^2+(-5)^2=17 \n25=17 \nnot \ true \n \nF(-2,6) \n(-2+3)^2+(6-2)^2=17 \n1^2+4^2=17 \n1+16=17 \n17=17 \ntrue

The answer is F(-2,6).

The diameter of a Frisbee is 12 in. What is the area of the Frisbee?a. 37.68 sq. in.
b. 452.16 sq. in.
c. 18.84 sq. in.
d. 113.04 sq. in.

Answers

we know that

Area of the circle is equal to

A=\pi r^(2)

where

r is the radius

in this problem

diameter=12\ in \n radius=diameter/2\n radius=12/2\n radius=6\ in

A=3.14* 6^(2)

A=113.04 in^(2)

therefore

the answer is the option

d. 113.04 sq. in.

The area of the Frisbee is about 113 in.² ( Option D )

Further explanation

The basic formula that need to be recalled is:

Circular Area = π x R²

Circle Circumference = 2 x π x R

where:

R = radius of circle

The area of sector:

\text{Area of Sector} = \frac{\text{Central Angle}}{2 \pi} * \text{Area of Circle}

The length of arc:

\text{Length of Arc} = \frac{\text{Central Angle}}{2 \pi} * \text{Circumference of Circle}

Let us now tackle the problem!

Given:

Diameter of Frisbee = d = 12 in

Unknown:

Area of Frisbee = A = ?

Solution:

Area of the Frisbee could be calculated using the area of circle as follows:

A = (1)/(4) \pi d^2

A = (1)/(4) * \pi * 12^2

A = 36 \pi ~ in.^2

A \approx \boxed {113.10 ~ in.^2}

The closest option available will be option D. 113 in.²

What are all the real zeros of y = (x - 12)3 - 10?

Answers

x = 3^√10 + 12

Is the right answer 100%
12 would be the only zero if you meant to write the equation as y=(x-12)(3-10)
