5 0

Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factorof two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2).Dilation with scale factor 2, multiply by 2.

Answer:

The answer would be c. 1440

Step-by-step explanation:

one of the angels would be 144 so you're gonna have to end up multiplying it by 10 which leads to 1440

The given lengths are two sides of a right triangle. All three side lengths of the triangle are integers and together form a pyt

Leni [432]

If all three side lengths are INTEGERS and form PYTHAGOREAN TRIPLE then we know decimals are not allowed

if 24 and 51 are both legs then
$24^{2} + 51^{2} = x^{2}$
x = 3177
and squre root of that gives us 56.364.... NOT an integer

So that means one of them is not a leg and since hypotenuse is longer than both legs, 51 must be the hypotenuse so to get the third side

$51^{2} - 24^{2} = x^{2}[tex] [tex] x^{2}$ =2025
x=45, leg B

Answer: The student’s values are accurate as well as precise.

Explanation:

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance three times and you get same value each time. Then the measurement is very precise.

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 50 kg and one person weighed 49 kg and another person weighed 48 kg. Then, the weight measured by first person is more accurate.

Given: Mass = 5.000 g

Mass weighed by A has values 4.891 g , 4.901 g and 4.890. Thus the average value is

Thus as the measured value is close to the true value, the student’s values are accurate and as the values are close to each other, the measurement is precise.
