<h3>Answer: Point E is located at (2, 3)</h3>

====================================

Explanation:

The sequence PQRST has T as the last letter.

The sequence ABCDE has E as the last letter

The two letters T and E pair up or they correspond. So T will rotate to land on point E. Or T will rotate to point E's location.

Point T is at location (-3,2). So x = -3 and y = 2.

-------

Use the rule

(x,y) ---> (y, -x)

which is the rule we use when we rotate any point 90 degrees clockwise around the origin. We swap the x and y coordinates, then change the sign of the second coordinate (after the swap happens).

This means,

(-3, 2) ----> (2, -(-3)) = (2, 3)

or simply

(-3, 2) ---> (2, 3)

In a math competition, every question that is answered correctly gets a score of 4. Wrong gets a score of -2. and not answered g

11111nata11111 [884]

Answer:

Step-by-step explanation:

First we need to find the score of the incorrect answers and the questions that were not answered.

Score for the incorrect answers = 4*(-2) = -8

Score for the questions not answered = 6*(-1) = -6

Score for the questions answered correctly = 106 - [ (-8) + (-6) ]

= 106 -[-14]

= 106 + 14

= 120

Number of questions answered correctly = total score for questions that were answered correctly ÷ score of 1 correct answer

= 120 ÷ 4

= 30

30 questions were answered correctly.

LAW OF SINES ANYONE?? need good explanation..ill give brainlest

Dominik [7]

Step-by-step explanation:

So i will try to explain it:

Scientists in the past invented this formula and theory of sines:

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) } = \frac{c}{ \sin(c) }$

So the only thing is to put the given numbers into this formula :)

The task that i've just done is like this:

$\frac{a}{ \sin(a) }$

a is the numerator,that is delighted in the triangle,well its transparent.

What about denominator?

Here is the tip:

opposite to A- side angle-a has to be put into sin(a)

sin- how to calculate?

Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) }$

one of this numbers might be unknown in that case solve by proportion(equation).

Carefully contemplate my answer in the media.

I hope you understood.

Good luck!

A monkey weighs 8.2 kilograms. How many grams does the monkey weigh? Use the number of zeros of the product when multiplying a n

Kobotan [32]

Answer:

m = 8.2 × 10³ grams

Step-by-step explanation:

Given that,

The weight of a monkey = 8.2 kilograms.

We need to convert its mass from kilograms to grams.

We know that,

1 kg = 1000 grams

1 kg = 10³ grams

In 8.2 kg,

8.2 kg = 8.2 × 10³ grams

Hence, the weight of the monkey is equal to 8.2 × 10³ grams.

Find the y intercepts of 3x^2+24x-51. quadratic formula

julia-pushkina [17]

Quadratic Formula: $x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$ , with a = x^2 coefficient, b = x coefficient, and c = constant.

Firstly, starting with the y-intercept. To find the y-intercept, set the x variable to zero and solve as such:

$y=3*0^2+24*0-51\\y=0+0-51\\y=-51$

<u>Your y-intercept is (0,-51).</u>

Next, using our equation plug the appropriate values into the quadratic formula:

$x=\frac{-24\pm \sqrt{24^2-4*3*(-54)}}{2*3}$

Next, solve the multiplications and exponent:

$x=\frac{-24\pm \sqrt{576-(-648)}}{6}\\\\x=\frac{-24\pm \sqrt{576+648}}{6}$

Next, solve the addition:

$x=\frac{-24\pm \sqrt{1224}}{6}$

Now, simplify the radical using the product rule of radicals as such:

Product Rule of Radicals: √ab = √a × √b

√1224 = √12 × √102 = √2 × √6 × √6 × √17 = 6 × √2 × √17 = 6√34

$x=\frac{-24\pm 6\sqrt{34}}{6}$

Next, divide:

$x=-4\pm \sqrt{34}$

<u>The exact values of your x-intercepts are (-4 + √34, 0) and (-4 - √34, 0).</u>

Now to find the approximate values, solve this twice: once with the + symbol and once with the - symbol:

$x=-4+ \sqrt{34},-4- \sqrt{34}\\x\approx 1.83, -9.83$

<u>The approximate values of your x-intercepts (rounded to the hundredths) are (1.83,0) and (-9.83,0).</u>
