B. 10.49823 (10.5 centimeters)

Simply reverse the formula for the volume of a sphere: pi*r^3*(4/3)

pi*r^3*(4/3)=4846.59
r^3*(4/3)=1524.71751128
r^3*4=4628.1523384
r^3=1157.03813346
r=10.49823
Round.

Answer:

Step-by-step explanation:

4/3 pi r3= 4846.59*3/4/pi=1157.625

so r3= 1157.625

so taking cube root on both sides we get

10.5 which is A

Three is a zero of the equation x^3−4x^2−3x+18=0. Which factored form is equivalent to the equation?

Novosadov [1.4K]

Answer:

$x_1=-2,\ x_2=x_3=3\\ \\(x+2)(x-3)^2=0$

Step-by-step explanation:

Consider the equation

$x^3-4x^2-3x+18=0$

The zeros of the equation can be the divisors of 18:

$\pm 1,\ \pm2,\ \pm3,\ \pm 6,\ \pm 9,\ \pm 18$

Check them:

$1^3-4\cdot 1^2-3\cdot 1+18=1-4-3+18=10\neq 0\\ \\(-1)^3-4\cdot (-1)^2-3\cdot (-1)+18=-1-4+3+18=16\neq 0\\ \\2^3-4\cdot 2^2-3\cdot 2+18=8-16-6+18=4\neq 0\\ \\(-2)^3-4\cdot (-2)^2-3\cdot (-2)+18=-8-16+6+18=0$

So, x=-2 is zero. Now

$x^3-4x^2-3x+18\\ \\=x^3+2x^2-6x^2-12x+9x+18\\ \\=x^2(x+2)-6x(x+2)+9(x+2)\\ \\=(x+2)(x^2-6x+9)\\ \\=(x+2)(x-3)^2$

Thus, x=3 is the second root (of multiplicity 2)

A person invests 9000 dollars in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long

il63 [147K]

Answer:

$7.4\ years$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=?\ years\\ P=\$9,000\\ r=0.06\\n=12\\ A=\$14,000$

substitute in the formula above

$14,000=9,000(1+\frac{0.06}{12})^{12t}$

$(14/9)=(1.005)^{12t}$

Apply log both sides

$log(14/9)=(12t)log(1.005)$

$t=log(14/9)/[(12)log(1.005)]$

$t=7.4\ years$

Answer:

ST is equal to TS because they are both the same line, just vertically flipped over the y-axis. Triangle RST is equivalent to Triangle UTS because they have the same area. (Rectangle cut into two equal-sized triangles)
