Answers

Answer 1

Answer:

Picture 1:

Area of cemicircle 2 π = 6.28 sq.m (approximately)

Total area of figure = 24+6.28= 30.28 sq.m (approximately)

Picture 2:

area of rectangle = 256 sq.m

Area of triangle = 32 sq.m

Total area of figure = 288 sq.m

Picture 3:

Area of top rectangle = 2 sq ft

Area of bottom rectangle = 15 sq ft

Total area of figure = 17 sq ft

Picture 4:

Area of rectangle = 28 sq ft

Area of triangle = 6 sq ft

Area of shaded region = 22 sq ft

QuestionEnter the exponential function using t (for time) as the independent variable to model the situation. Thenfind the value of the function after the given amount of time.A new savings account is opened with $400 and gains 3.5% yearly for 5 years.The exponential function that models the situation is y = MyAfter 5 years, the savings account has $

Answers

Since, it is an exponential function, thus this is a compound interest problem;

Where; the function is given as;

$\begin{gathered} A(t)=P(1+r)^t \n \text{Where A(t)= amount in the savings account at a time t} \n P=ca\text{ pital invested} \n r=\text{rate } \n t=\text{ time} \end{gathered}$

Thus, the function required is;

$\begin{gathered} A(t)=400(1+(3.5)/(100))^t \n A(t)=400(1.035)^t \end{gathered}$ $\begin{gathered} y=400(1.035)^t \n \text{Where t is the time} \end{gathered}$

After 5 years,

$\begin{gathered} A(5)=400(1.035)^5 \n A(5)=400(1.1877) \n A(5)=475.07 \end{gathered}$

The amount in the savings account after five years is $475.07

What is the solution to 3/4 a>-16?O a>-21/3
O a<-21
O a> 21-1/
O a <21/13

Answers

$\huge\text{Hey there!}$

$\huge\textbf{Equation:}$

$\mathsf{(3)/(4)a > -16}$

$\huge\textbf{Simplifying it:}$

$\mathsf{(3)/(4)a > -16}$

$\mathsf{(3)/(4)a > - (16)/(1)}$

$\huge\textbf{Divide \boxed{(4)/(3)} to both sides:}$

$\mathsf{(4)/(3)*(3)/(4)a > -16*(4)/(3)}$

$\huge\textbf{Simplify it:}$

$\mathsf{a > (4)/(3)* -16}$

$\mathsf{a > - (16)/(1) *(4)/(3)}$

$\mathsf{a > (-16*4)/(1*3)}$

$\mathsf{a > (-64)/(3)}$

$\mathsf{a > -(64)/(3)}$

$\mathsf{a > -21 (1)/(3)}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{- \frak{21(1)/(3)}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$

$(3a)/(4) > - 16 \n 3a > - 64 \n a > ( - 64)/(3) \n a > 21 (1)/(3)$

Factor the trinomial.
The factors of m2 + 12m + 35

Answers

Answer:

(m + 7)(m + 5)

Step-by-step explanation:

Factor, find factors of m² & 35 that, when combined, will give 12m:

m² + 12m + 35

m 7

m 5

(m + 7)(m + 5) is your answer.

Check: Use the FOIL method to check.

(m)(m) = m²

(m)(5) = 5m

(7)(m) = 7m

(7)(5) = 35

Combine like terms:

m² + (5m + 7m) + 35 = m² + 12m + 35 √.

Answer:

(m+7) and (m+5)
