Step-by-step explanation:

21/4 (but since you can't have part of an orange) it would be 20/5=4

this means there are 4 times oranges are picked, and 2 per time so 4x2=8

Naomi deposited money into savings account that is compunded quarterly at an interest rate of 6%. She thinks this quarterly rate

FromTheMoon [43]

Answer:

No, because 1.25% times 3 is 3.75% which is less than 6%

Step-by-step explanation:

Quarterly is every 3 months

6% interest is 1.06, 6 cents on the dollar

Monthly interest rate is 1.25% so 1.25 × 3 is 3.75

So, 1.25% times 3 is 3.75% which is 2.25% less than 6%

Hope this helps!

Have a great day!

Given: the function defined by f(x)=3x^2-4 Which statement is true? 1. f(0) = 0 2. f(-2) = f(2) 3. f(5)+ f(2) = f(7) 4. f(5) x f

sergeinik [125]

$f(x)=3x^2-4 \\ \Downarrow \\ f(0)=3 \times 0^2-4=0-4=-4 \\ -4 \not= 0 \\ f(0) \not= 0 \\
\hbox{statement 1 is false} \\ \\
f(-2)=3 \times (-2)^2-4 =3 \times 4-4=12-4=8 \\
f(2)=3 \times 2^2-4=3 \times 4-4=12-4=8 \\ 8=8
\\ f(-2)=f(2) \\
\hbox{statement 2 is true}$

$f(5)=3 \times 5^2-4=3 \times 25-4=75-4=71 \\ f(2)=8 \\
f(7)=3 \times 7^2-4=3 \times 49-4=147-4=143 \\
71+8 \not= 143 \\
f(5)+f(2) \not= f(7) \\ \hbox{statement 3 is false} \\ \\
f(5)=71 \\ f(2)=8 \\ f(10)=3 \times 10^2-4=3 \times 100-4=300-4=296 \\
71 \times 8 \not= 296 \\
f(5) \times f(2) \not= f(10) \\
\hbox{statement 4 is false}$

Stamement 2. f(-2)=f(2) is true.
