1 answer:

7 0

Formula for the volume of the sphere
$\frac{4}{3} \times \pi \times {r}^{3}$
$= 1436.755$
$\frac{1436.755}{\pi \times \frac{4}{3} } = {r}^{3} \\r = 6.999999935 \\ d = 13.999999$

Find the tangent of each angle that is not the right angle. Drag and drop the numbers into the boxes to show the tangent of each

omeli [17]

Answer:

tan D = $\frac{6}{11}$ or 0.545

tan F = $\frac{11}{6}$ or 1.833

Step-by-step explanation:

To find tangent is always $\frac{opposite}{adjacent}$

so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8 so $\frac{4.8}{8.8}$ which is $\frac{6}{11}$ or 0.545

The opposite of angle f is line ED which is 8.8 and the adjacent is line EF which is 4.8 so $\frac{8.8}{4.8}$ is $\frac{11}{6}$ or 1.833

Explain in words how you would graph the following inequality on a number line. 3x < 12 HELPPPPPPPPPPP PLSSSSSS

AnnyKZ [126]

Answer:

x<4

Step-by-step explanation:

3x < 12

Divide with 3 on each side

x< 4

In words x has all the real numbers that are less than 4 or x belongs to any number from -ve infinity to 4.

A polynomial function of degree 4 with real coefficients could have -3, 1+i, 1-i, and -3,7i as its zeros. true or false

Novosadov [1.4K]

Using complex numbers concepts, it is found that the statement is false.

When a complex number is a root of a polynomial function, it's conjugate also has to be.

A complex number has the format $a + bi$ , and it's conjugate is $a - bi$ .

In this problem:

Real root -3.
Complex-conjugate roots 1 + i and 1 - i.
Complex root -3 + 7i.

The conjugate of -3 + 7i also has to be a root, which would make the polynomial of the 5th degree, as it would have 5 roots, thus, the statement is false.
