I’m currently working on my quadrilaterals unit (specifically with trapezoids & kites) and I need major help on a lot of the

se problems.
Here’s one of them I need help solving (an answer would be preferable, but also an explanation.):

Answer: 29.2

Step-by-step explanation:

The lengths of the two longer legs are both \sqrt{8^2 + 4^2}=\sqrt{80}

The lengths of the two shorter legs are both \sqrt{4^2+4^{2}}=\sqrt{32}

So P=2\sqrt{80}+2\sqrt{32} \approx 29.2

_____ refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.
Setler79 [48]

Answer:

Internal validity

Step-by-step explanation:

Internal validity is a scientific study that emphasize on the fact that there is a proof to validate a specific study. Let's say i'm a forensics scientist for example; and there was a recent crime scene in some nearby sub-urban area which demands our call, when present at the scene, The main task there is to gather information as much as we can  which is required to be investigate in the laboratory for further analysis.The process of information gathering is our independent variables which varies with different causes of the crime, the laboratory analysis that make deductions (which is cause by some manipulation) of the information gathered is our dependent variables.

Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.

The equation y= 1/2 x +4 is graphed below.which equation would intersect this line at (4, 6)?
Anton [14]

Answer:

we have the equation y = (1/2)*x + 4.

now, any equation that passes through the point (4, 6) will intersect this line, so if we have an equation f(x), we must see if:

f(4) = 6.

if f(4) = 6, then f(x) intersects the equation y = (1/2)*x + 4 in the point (4, 6).

If we want to construct f(x), an easy example can be:

f(x) = y = k*x.

such that:

6 = k*4

k = 6/4 = 3/2.

then the function

f(x) = y= (3/2)*x intersects the equation  y = (1/2)*x + 4 in the point (4, 6)
