The correct answer is B. Line graph
Explanation:
A line graph is ideal to show a variable or factor over time, this is because in a line graph you use dots to depict whether the factor studied decreases or increases. This will be ideal to show how the weight of an infant changes during eight visits because by using this graph the doctor can clearly show the increase or decrease of this factor over time. On the other hand, a bar graph is used to compare different elements in one category simultaneously, while a circle graph is used to show percentages of total and a stem-and-left plot shows complex numerical information.
Answer: 7 gallons
Step-by-step explanation:
85 + 125
210 miles from Central City to Jonesburg
30 miles per gallon so divide 210 miles by 30 miles to get gallons
210 ÷ 30
7 gallons
Hope this helps!
Answer:
0.66
Step-by-step explanation:
The exponential growth equation is expressed as;
S(t) = S0e^kt
S(t) is the number of stores after t years
S0 is the initial number of stores
If a chain of retail computer stores opened 2 stores in its first year of operation then at t = 1, S(t) = 2. Substitute into the equation;
2 = S0e^k(1)
2 = S0e^k .... 1
Also if after 8 years of operation, the chain consisted of 206 stores, this means at t = 8, S(t) = 206. Substitute into the equation;
206 = S0e^k(1)
206 = S0e^8k .... 2
Next is to calculate the value of k
Divide equation 2 by 1;
Hence the value of k to the nearest hundredth is 0.66
R=C over 2pie, so r= 50.24/2(3.14) so its about 8cm
