Answer:third graph (open circle on 518, colored to the right)

Step-by-step explanation:The record is 518 cm. That means that 518 cm has already been accomplished. Anything less than 518 cm is not a record. 518 cm is also not a record. Only distances greater than 518 cm are records

In △ABC,∠B is a right angle. The coordinates for each point are A(10, 7), B(5, 9), and C(3, 4). Rounded to the nearest tenth,

shepuryov [24]

Answer:

$A=14.5\ units^2$

Step-by-step explanation:

we know that

The area of the right triangle ABC is equal to

$A=\frac{1}{2}(AB)(BC)$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

A(10, 7), B(5, 9), and C(3, 4)

step 1

Find the distance AB

A(10, 7), B(5, 9)

substitute in the formula

$d=\sqrt{(9-7)^{2}+(5-10)^{2}}$

$d=\sqrt{(2)^{2}+(-5)^{2}}$

$d_A_B=\sqrt{29}\ unjts$

step 2

Find the distance BC

B(5, 9),C(3, 4)

substitute in the formula

$d=\sqrt{(4-9)^{2}+(3-5)^{2}}$

$d=\sqrt{(-5)^{2}+(-2)^{2}}$

$d_B_C=\sqrt{29}\ unjts$

step 3

Find the area

substitute the values

$A=\frac{1}{2}(\sqrt{29})(\sqrt{29})$

$A=14.5\ units^2$

if x is a positive integer, for how many dofferent values of x is square root 48 over x a whole number

Mazyrski [523]

Answer:

<h2><em>Therefore, for 3 values of 'x', the given fraction is a square. So, for those 3 values of 'x', the square root of the fraction will be a whole number. Thus, the answer is 3.</em></h2>

Which shows the dilation with a possible scale factor if 1/2

NikAS [45]

Answer:

There is no diagram or any information of what you are dilating but a simple tip is to DIVIDE THE TARGET BY 2

Step-by-step explanation:

You would divide by two because you're dilating by 1/2
