$f(x) = - {x}^{3} - {x}^{2} + 1$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f( - 1) = - ({ - 1})^{3} - ({ - 1})^{2} + 1 \\$

$f( - 1) = - ( - 1) - (1) + 1$

$f( - 1) = 1 - 1 + 1$

$f( - 1) = 2 - 1$

$f( - 1) = 1$

MAX POINTS PLS ANSWER CORRECTLY OR WILL REPORT ty !

Oksana_A [137]

Answer:

136112 $cm^{2}$

Step-by-step explanation:

since the outer circle is 25cm wider on one side, the radius of outer circle is 25 cm wider. (imagine rotating the green line to match with the pink line, you'll see the outer circle radius more clearly)

r of inside circle = 148.4/2 = 74.2

r of outside circle = 74.2 +25 = 99.2

the shaded region = A of outer circle - A of inner circle

=3.14(99.2)^2 - 3.14(74.2)^2

area of a circle is $\pi r^{2}$ , I plugged in known values above^.

= 30899.6096 - 17287.7096 = 13611.9 (I definitely recommend a calculator)

rounded to nearest whole number = 13612

If c+1/d=5 , what is the value of 30d/2c+2

klemol [59]

Answer:

$d\in R,\hspace{5}d\neq 0$

Step-by-step explanation:

You can solve for any variable. From the first equation, let's solve for c :

$\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1$

Now, replace the value of c into the other equation:

$\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\$

Using distributive property

$\frac{30d}{10d-2+2} =\frac{30d}{10d} =3$

However, keep in mind that this is true for:

$d\in R,\hspace{5}d\neq 0$

Which term of the arthemetic sequence (1, 3, 5, 7) is equal to 141

Dmitry_Shevchenko [17]

Answer:

71th term is 141

Step-by-step explanation:

$a_{1}=1\\\\common \ difference = d = second \ term - first \ term\\\\ = 3 - 1 = 2\\\\a_{n} = 141\\\\a + (n -1)*d = a_{n}$

1 + (n - 1)*2 = 141 {Use distributive property}

1 + 2n - 2 = 141

2n - 1 = 141

2n = 141 + 1

2n = 142

n = 142/2

n = 71
