Point B has coordinates (3,2). The x-coordinate of point A is negative 3. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
The possible coordinates of point A are
Answers
Answer:
Either A= (-3,10)
OR A= (-3,-6)
Step-by-step explanation:
A = (-3,y) B = (3,2)
(Distance from A to B) = √[(-3-3)²+(y-2)²]=10
√[36+y²-4y+4]=10
√[y²-4y+40]=10
squaring on both sides
y²-4y+40=100
y²-4y-60=0
y²-10y+6y-60=0
y(y-10) + 6 (y-10)=0
(y - 10)(y + 6)=0
Either y=10 =>A= (-3,10)
OR y=-6 =>A= (-3,-6)
If 1/10 < x < 1, for what value of x is the value of 10 + 1/x greatest?
Help quick pleaseee
Answers
Answer:
Step-by-step explanation:
We can safely focus on 1/x. The smaller x is, the greater 1/x will be. Note that x cannot equal zero. Here we are asked to focus on 1/10 < x < 1, in which 1/10 is obviously the smallest x value. But 1/10 < x < 1 restricts x to numbers greater than 1/10. The graph of y = 10 + 1/x is not defined for x = 1/10, but as we approach x = 1/10 along the graph, we see the graph approaching (but not touching) the maximum value 10 + 1/(1/10), or 20.
Bald-faced hornets have a hive that is approximately cone-shaped, as shown in the image. One such hive has a radius of 15 inches and a height of 20 inches.
The volume of this hive is approximately _[blank]_ π in3.
Enter your answer as the correct value, rounded to the nearest tenth, if necessary, like this: 42.5
Answers
Answer:
5340.7
Step-by-step explanation:
So the volume of a cone is πr^2 * h / 3
r = 15
h = 20
225π * 20 / 3 ≈ 5340.7
Approximately 5340.7

5x+34+8x+15=88
step by step
Let's solve your equation step-by-step.
5x+34+8x+15=88
Step 1: Simplify both sides of the equation.
5x+34+8x+15=88
(5x+8x)+(34+15)=88(Combine Like Terms)
13x+49=88
13x+49=88
Step 2: Subtract 49 from both sides.
13x+49−49=88−49
13x=39
Step 3: Divide both sides by 13.
13x

Find the sum of the numbers as a product of their GCF is 84 + 108
Answers
Hey there! :)
I believe the correct answer to your question is 12.
Find the prime factorization of 84
84 = 2 × 2 × 3 × 7
Find the prime factorization of 108
108 = 2 × 2 × 3 × 3 × 3
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 2 × 3
GCF = 12

Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?
Answers
Answer:
3
Step-by-step explanation:
Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

50 POINTS find the length of ab plz help me
Answers
Answer:
about 9.4 units
Step-by-step explanation:
Distance formula:
√(x1 - x2)² + (y2 - y1)²
Coordinates:
A (4, 2)
B (9, 10)
Let's make 9 = x1
Let's make 4 = x2
Let's make 10 = y1
Let's make 2 = y2
Substitute into the distance formula:
√(x1 - x2)² + (y2 - y1)²
√(9 - 4)² + (2 - 10)²
Solve:
√(9 - 4)² + (2 - 10)²
√(5)² + (-8)²
√25 + 64
√89
≈ 9.4
Therefore, the length of AB is approximately 9.4 units.
Answer:
About 9.4 units
Step-by-step explanation:
To find the distance between two points
d = sqrt(( y2-y1) ^2 + (x2-x1) ^2) where (x1,y1) and (x2,y2) are the points
= sqrt(( 10-2)) ^2 + (9-4) ^2)
= sqrt((8) ^2 + (5) ^2)
= sqrt(64+ 25)
= sqrt(89)
=9.433981132
