Given:

$f(x)=3x^2-5x-2$ ; find f(-2/3)

Answer:

$f(-\frac{2}{3} )=\frac{8}{3}$

Step-by-step explanation:

1. Insert $-\frac{2}{3} \\$ as X; $f(-\frac{2}{3}) = 3 (-\frac{2}{3} )^2 - 5 (-\frac{2}{3}) - 2$

2. Solve equation; $f(-\frac{2}{3} )=\frac{8}{3}$

Answer:

$\large\boxed{\ln\sqrt[3]{e^4}=\dfrac{4}{3}}$

Step-by-step explanation:

$\text{Use}\\\\\sqrt[n]{a^m}=a^\frac{m}{n}\\\\\ln a^n=n\ln a\\\\\ln e=1\\-----------\\\\\ln\sqrt[3]{e^4}=\ln e^\frac{4}{3}=\dfrac{4}{3}\ln e=\dfrac{4}{3}\cdot1=\dfrac{4}{3}$

Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?

Sophie [7]

Here are the numbers
4.3 , 5.5 , 6 $\frac{1}{6}$ , $\frac{15}{4}$ , 4 $\frac{3}{8}$
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
$6\frac{1}{6}$ <em />⇔6.1666---
$\frac{15}{4}$ ⇔3.75
$4 \frac{3}{8}$ ⇔4.375
Now to arrange them from least to the greatest
$\frac{15}{4}$ , 4.3 , $4 \frac{3}{8}$ , 5.5 , $6\frac{1}{6}$

Evaluate the expression 3.14(a2 + ab) when a = 3 and b = 4. (Input decimals only, such as 12.71, as the answer.)

Rama09 [41]

A= 3
b= 4

=3.14(a^2 + ab)
substitute the given a & b values in expression

=3.14((3)^2 + (3*4))
multiply inside parentheses

=3.14(9 + 12)
add inside parentheses

=3.14(21)
multiply

=65.94

ANSWER: 65.94

Hope this helps! :)
