3. In ΔABC, AB = 5 inches and BC = 3 inches. Which of the choices represents all possible values for AC, in inches?
Answers
Answer:
2< AC<8
Step-by-step explanation:
For a triangle to exits sum of two sides must always be greater than the the third side
⇒ AC< AB+ BC =5+3=8 in
⇒AC<8 in
Also, the difference of the two sides must be smaller than the length of third side
⇒ AC> | AB-BC| = |5-3| =2
AC> 2 in
therefore, we can say 2< AC<8. Hence, AC can takes 3,4,5,6 values

D. proportional
E.
When x is 0, y is
F. When y is 2, x is 2 or -2.
Answers
According to the linear function concept, the correct answer is:
B. linear
Additionally:
When x = 0, [tex]\frac{8}{7}[/tex].When y = 2, x = -2.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the function is:
[tex]3x + 7y = 8[/tex]
Placing into standard format:
[tex]7y = 8 - 3x[/tex]
[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]
Hence it is a linear function.
When x = 0:
[tex]y = \frac{8}{7} - \frac{3(0)}{7} = \frac{8}{7}[/tex]
When y = 2:
[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]
[tex]2 = \frac{8}{7} - \frac{3x}{7}[/tex]
[tex]8 - 3x = 14[/tex]
[tex]3x = -6[/tex]
[tex]x = -\frac{6}{3}[/tex]
[tex]x = -2[/tex]

Heather invests $3572 in a retirement account with a fixed annual rate of 5% compounded 4 times per year what will the account balance be after 16 years
Answers
Answer:
$7910.3
Step-by-step explanation:
Given data
P=$3572
n=4
T=16 years
R= 5%
The compound interest is expressed as
A= P(1+r/n)^nt
Substitute
A=3572(1+0.05/4)^16*4
A=3572(1+0.0125)^64
A=3572(1.0125)^64
A=3572*2.21453241061

Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?
Answers
Answer:
$14 9/10
Step-by-step explanation:
Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?
From the above question,
$30 = Gift A + Gift B + Gift C
She spent 9 7/ 10 dollars on gift A and 5 2/5 dollars on gift B.
$30 = $9 7/10 + $5 2/5 + Gift C
Gift C = $30 - ( $9 7/10 + $5 2/5)
Lowest Common Denominator = 10
Gift C = $30 - $14+(7 + 4/10)
Gift C = $30 - $14+(7 + 4/10)
Gift C = $30 - $14+(11/10)
$30 - $14+(1 1/10)
$30 - $15 1/10
Gift C = $14 9/10
Therefore, the amount of money she had left for gift C is $14 9/10
