Mathematics
1 answer:
VashaNatasha [74]2 years ago

The answer you are looking for is 9.

Solution/Explanation:

Writing out the expression first

√-3√-27

Don't worry. You are overthinking it. All you actually have to do is multiply both of them together

So,

√-3√-27=√81

Then, you will get √81.

This will simplify to 9. So, therefore, the final answer is 9.

Hope this helped you. Good day to you.

Determine the center and radius of the following circle equation:<br> x? + y2 - 2x - 12y +36 = 0
Gre4nikov [31]

Step-by-step explanation:  

x²+ y² -12x - 18y +17 = 0 means : (x²-12x+36)-36+(y²-18y+81)-81-27 =0

(x-6)²+(y-9)² =12²....standard form when the center is (-6 , 9) and radius 12

Amanda and jamie are standing 25 feet apart and spot a bird in the sky between them the angle of elevation from Amanda is 25 fee
finlep [7]

Answer:

25.2294 feet

Step-by-step explanation:

We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).

First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:

y + 55 + 63 = 180

y = 62°

The relation between the angles and the distances are:

25 / sin(y) = x / sin(63)

25 / 0.8829 = x / 0.8910

x = 25 * 0.8910 / 0.8829 = 25.2294 feet

The weights in pounds of 6 members of a basketball team are 125, 136, 150, 119,
Roman55 [17]

Answer:

Mean:(137.2)

Median:(139.5)

Step-by-step explanation:

Mean = (125+136+150+119+143) divide by six(6)

= 823/6 = approx 137.2

Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.

119,125,136,143,150, 150. so 136 & 143 is the middle number.

so you will add the middle number and divide by 2.

that is 136+143/2 = 139.5.
