Step-by-step explanation:
write the equation of circle b with center B(-2,3) that passes through (1,2)
Answer:
[tex](x+2)^2 + (y-3)^2 = 10[/tex]
Step-by-step explanation:
The standard equation for circle is
[tex](x-a)^2 + (y-b)^2 = r^2[/tex]
where point (a,b) is coordinate of center of circle and r is the radius.
______________________________________________________
Given
center of circle =((-2,3)
let r be the radius of circle
Plugging in this value of center in standard equation for circle given above we have
[tex](x-a)^2 + (y-b)^2 = r^2 \ substitute (a,b) \ with (-2,3) \\=>(x-(-2))^2 + (y-3)^2 = r^2 \\=>(x+2)^2 + (y-3)^2 = r^2 (1)[/tex]
Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.
Plugging in the point (1,2 ) in equation 1 we have
[tex]\\=>(x+2)^2 + (y-3)^2 = r^2 \\=> (1+2)^2 + (2-3)^2 = r^2\\=> 3^2 + (-1)^2 = r^2\\=> 9 + 1 = r^2\\=> 10 = r^2\\=> r^2 = 10\\[/tex]
now we have value of r^2 = 10, substituting this in equation 1 we have
Thus complete equation of circle is [tex]=>(x+2)^2 + (y-3)^2 = r^2\\=>(x+2)^2 + (y-3)^2 = 10[/tex]

Answer:
14.25-d
Step-by-step explanation:
The original amount of money he has is 14.25 so that is the first number in your equation. H ethen buys the card which costs (d) dollars so you are subtracting that from 14.25 since he is spending it. This means the final equation is 14.25-d.
What is the distance between points A(1,9) and B(4, -2)?
What is the volume of the composite solid?
Answer:
Step-by-step explanation:
In order to find the volume of a composite solid, one needs to identify the different parts it is made of. This decomposition allows working out the volume of each part independently. The volume of the composite solid is simply the sum of the volumes of its parts.
work out the size of angle y
Answer:
Angle y= 108 degrees
Step-by-step explanation:
2x+16= 3x-12 (corresponding angles)
3x-2x=16+12
x=28
3(28)-12= 72
180-72=108 degrees
which step is first?
Answer:
B
Step-by-step explanation:
You want to isolate 2W, which would be accomplished by subtracting 2L. Then you want to remove the 2 from the W and to do that you divide both sides by 2

The correct answer is D.
SuperCaff Cola conducted a survey to gauge the effectiveness of their advertising. The researchers estimated from the survey that between 7% and 37% of the target population remember the ads. What was the margin of error for this research?
+/- 5%
+/- 10%
+/- 15%
It is not possible to determine the margin of error from this information.
Answer:
It is not possible to determine, because there is not enough information.

Solve the equation for x, in simplest form x+3/8=1/4
Answer:
x = -1/8
Step-by-step explanation:
x + 3/8 = 1/4
Subtract 3/8 from both sides.
x = 1/4 - 3/8
The LCD is 8.
x = 2/8 - 3/8
x = -1/8
Answer:
1/8
Step-by-step explanation:
1/4 = 4/8
4/8-3/8 = 1/8
0.25- 0.375 = 0.125
0.125 = 1/8
Maia and John both earn $15 an hours their job. This week Mais worked three hours more than John. If "h" represents the number of hours John worked, and in total they earned $195, how many hours did each person work?
Answer:
John: 5 Mais :8
Step-by-step explanation:
h = 195 ÷ 15, so they both worked a total of 13 hours.
13 - 3 as Mais worked 3 hours more than John and then divide 10 by 2, so John worked 5 hours are Mais worked 5+3 [8] hours.

In that school, what is the ratio of the number of students who like math to the number of students who like science? (see picture)
Answer: 1/2:1/3
I hope this helps
Step-by-step explanation:
In the problem it says 1/2 of the students in the school like math, and it also says in the problem that 1/3 of the students in the school like science. The question is asking for a ratio of students who like math to students who like science, so now the only thing you need to do is input those 2 numbers in the order that they want it in. Which is 1/2:1/3. And don't forget that the colon : is what you always put in between the two numbers.

Is 3x+0y a monomial, binomial or trinomial?
Answer:
trinomial
Step-by-step explanation:
it has 3 terms. an expression with three terms is a trinomial.
(mark as brainliest)
Answer:
the answer would be monomial
because there is one term it is 3x
0y is not term
Which properties are present in a table that represents an exponential function in the form y=b^x when b > 1? I. As the x-values increase, the y-values increase. II. The point (1, 0) exists in the table. III. As the x-values increase, the y-values decrease. IV. As the x-values decrease, the y-values decrease, approaching a singular value. I and IV I and II II and III III only
Answer:
Properties that are present are
Property I
Property IV
Step-by-step explanation:
The function given to us is where b > 1
Let us take a function, for example,
Now, let us check the conditions before we continue:
I. When the x-values increases, the y-values will also increase.
Let us put some values:
y = 2 ^ 1
which results to y = 2
and
y = 2 ^ 2
which results to y = 4
So this is definetly TRUE.
II. The point: (1,0) is in the table.
Ok, now let us put 1 into x and try to see if it gives us 0
y = 2 ^ 1
y = 2
So this is surely FALSE.
III. As the x-value increase, the y-value decrease.
We have already seen that as x increase, y also increase in part I.
So this is FALSE.
IV. as the x value actually decrease. Now, the y values decrease approaching a singular value.
The exponential function of this form will NEVER go to 0 and is NEVER negative. So as x decreases, y also decrease and came to a value (that is 0) but never becomes 0.
This is TRUE.
Therefore, Option I and Option IV are true.

What is the volume of the rectangular pyramid shown below?
9 in.
8 in.
7
in.
Answer:
Step-by-step explanation:
To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid's volume!
I cant do this until I know What number is what.
Which is length?
Which is height?
and which is width?
