5. What is the value of x to the nearest tenth? The figure is not drawn to scale.
Answers
Answer:
5.46
Step-by-step explanation:
Using pythagoras theorem;
AD^2 = 5.3^2 - 4.1^2
AD^2 = 28.09-16.81
AD^2 = 11.28
AD = √11.28
AD = 3.36
x^2 = 3.36^2+4.3^2
x^2 = 11.28 + 18.49
x^2 = 29.77
x = 5.46
Hence the value of x is 5.46

For given question,
The scatter plot with data points that form an upward curve staring at the origin and continuing to the right.
The graph represents an exponential function.
At (0, 1),
[tex]\Rightarrow 1=ab^0\\\Rightarrow a=1[/tex]
At (1, 4) we have,
[tex]\Rightarrow 4 = ab^1\\\Rightarrow 4=(1)b\\\Rightarrow b=4[/tex]
So, we have exponential function of the form [tex]y=4^x[/tex]
Hence, the function that best fits the data is [tex]y=4^x[/tex]

Molly bought c candy canes. She paid $1.05, including tax, per candy cane. She gave the cashier $10 and received $1.60 in change. How many candy canes did Molly purchase? Please hurry
Answers
Answer:
Number of candy = 8 candy canes.
Step-by-step explanation:
Cost per candy = $1.05
Amount paid = $10
Change received = $1.60
Total cost = amount paid - change received
Substituting into the equation, we have;
Total cost = 10 - 1.6
Total cost = 8.4
To find the number of candy purchased;
Number of candy = total cost/cost per candy
Number of candy = 8.4/1.05
Number of candy = 8 candy canes.
Therefore, Molly purchased 8 candy canes.

When a team brings 15 campers, the rate is reduced to $125 per camper. What is the rate of change in cost per camper ?
Answers
Answer: $6.67
Step-by-step explanation:
A volleyball camp chargers $150 per camper for 10 campers. The cost for each camper will be:
= $150/10
= $15
When a team brings 15 campers, the rate is reduced to $125 per camper. The cost for each camper will be:
= $125/15
= $8.33
The rate of change in cost per camper will be:
= $15 - $8.33
= $6.67

1. x≤5 Work: 2x+9≤19 move the constant to the right then its 2x≤19-9, then subtract the numbers and it would be 2x≤10, then divide both sides of the inequality by 2 which gives you the final answer of x≤5
2. x≥19 Work: x-7≥12 move the constant to the right then its x≥12+7, then add the numbers and get your final answer of x≥19
3. x≤4 Work: Divide both sides of the inequality by -3 and flip the inequality sign and that gives you -3÷(-3)≤-12÷(-3) and divide that which gives you x≤4
4. x<-3 Work: move the constant to the right which gives you -5x>16-1, then subtract to get -5x>15 and divide both sides of the inequality by -5 and flip the inequality sign to get x<-3
