Suppose ray AT bisects Angle CAR. If the measure of Angle CAT is 5x, and

Tema [17]

Answer:

x=7

Step-by-step explanation:

since the ray bisects we know <CAT and <TAR are equal

so we can set up the equation like this: <CAT + <CAT = <CAR

(5x)+(5x)=(9x+7)

calculate equation and you'll get x=7

The RANGE of the function is

forsale [732]

Answer:

Range is [1, ∞)

Step-by-step explanation:

The values of x can be 1 up to infinity (the domain).

When x = 1 , f(x) = 1^2 = 1

when x = ∞, x^2 = ∞

So the range is [1, ∞)

Is 0.144 rational or irrational ?

madam [21]

Irrational numbers can be written as decimals but not as fractions.

0.144 is a decimal, but it can also be written as 18/125. So this is a rational number.

√0.144 is equal to 0.3794733192. It cannot be expressed into a fraction. So, this is an irrational number.

√0.0144 is equal to 3/25. So, this is a rational number.

I hope I was able to help you. Have a good day.

DO NOT ANSWER W/O EXPLANATION PLEASE! NEED WRITTEN SOLUTION.

We have altitude h to side AB and AB=h, i.e. the altitude is congruent to the side it goes to.

That's all kinds of triangles. One way to see them is using two horizontal parallel lines h apart, the bottom one with a base AB=h somewhere on it. Then any C on the top line makes a triangle ABC with altitude h=AB.

Let's go through the choices.

I. ABC could be a right triangle. That's TRUE.

We could have the isoscleles right triangle, C directly above B, so AC is the leg and an altitude, AB=AC and B is the right angle.

II. Angle C cannot be a right angle. That's TRUE.

The biggest angle C can be is when it's over the midpoint of AB, so if AB=2, h=2, and

$AC=\sqrt{2^2+1^2}=\sqrt{5}$

$C_{\textrm{max}} = 2 \arctan(1/2) \approx 53.13^\circ$

III. Angle C could be less than 45 degrees. That's TRUE.

As long as C stays on our top parallel, we can make it as acute as we like by going farther away from AB.

All true. Hmmm.
