Mathematics

Allisa [31]4 years ago

The total area is:
 A = Ab + Al
 Where,
 Ab: base area
 Al: lateral area
 We have then:
 For the base area:
 Ab = (2) * (2)
 Ab = 4 units ^ 2
 For the lateral area:
 Al = (4) * (1/2) * (2) * (root ((1) ^ 2 + (3) ^ 2))
 Al = (4) * (root (1 + 9))
 Al = 4raiz (10) units ^ 2
 Total area:
 A = 4 + 4raiz (10)
 Answer:
 
A = 4 + 4raiz (10)

The answer to this is: A = 4 + 4raiz (10)

Formula: A = Ab + Al Where, Ab= base area A= lateral area


 For the base area: Ab = (2) * (2) Ab = 4 units ^ 2

 For the lateral area: Al = (4) * (1/2) * (2) * (root ((1) ^ 2 + (3) ^ 2)) Al = (4) * (root (1 + 9)) Al = 4raiz (10) units ^ 2

 Total area: A = 4 + 4raiz (10)

What is the soulution to the compound inequality 2<3x-1-<5
zzz [600]
2 < 3x - 1 < 5 ....add 1 to all sections
2 + 1 < 3x - 1 + 1 < 5 + 1 ...simplify
3 < 3x < 6...now divide all sections by 3
3/3 < (3/3)x < 6/3...simplify
1 < x < 2 <===

but if u have trouble doing it this way, u can split it
2 < 3x - 1                    3x - 1 < 5
2 + 1 < 3x                   3x < 5 + 1
3 < 3x                          3x < 6
3/3 < x                          x < 6/3
1 < x                             x < 2
now put them together.....1 < x < 2 <==

either way, u will get the same answer

How much must be deposited today into the following account in order to have $ 65,000 in 8 years for a down payment on a​ house?
svp [43]

Answer:

\$47,494.86

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=8\ years\\ A=\$65,000\\ r=4\%=4/100=0.04\\n=1  

substitute in the formula above  

65,000=P(1+\frac{0.04}{1})^{1*8}  

65,000=P(1.04)^{8}  

Solve for P

P=65,000/(1.04)^{8}  

P=\$47,494.86

M = 2/3, B = -5<br> M = -5, b = 3/2<br> M = 2, b = -6<br> M = -5, b= 2
MA_775_DIABLO [31]

Answer: m = 3/2, b = -5

Step-by-step explanation:

When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.
