7x + 5y = −35
The x−intercept is
.(blank)
The y−intercept is
(blank)
need x and y intercepts
Step-by-step explanation:
7x + 5y = −35
7(0)+5y=-35
0+5y=-35
0 0
5y= -35
5y/5= -35/5
y= -7
7x + 5y = −35
7x+5(0)=-35
7x+0=-35
0 0
7x= -35
7x/7= -35/7
x= -5

Substitute x = 3 - 2 cos(θ) and dx = 2 sin(θ) dθ (where "sin" = "sen"). So we have
∫ sin(θ) / (3 - 2 cos(θ)) dθ = 1/2 ∫ 1/x dx
= 1/2 ln|x| + C
= 1/2 ln(3 - 2 cos(θ)) + C
(We can remove the absolute value because -1 ≤ cos(θ) ≤ 1, so 1 ≤ 3 - 2 cos(θ) ≤ 5, and |x| = x when x ≥ 0.)

Answer:
66.4, 70.4, 223.2
Step-by-step explanation:
make the equation x + (x+4)+ 3x+24=360
then it's 5x+28=360
subtract 28 on both sides
5x=332
then divide by 5 on both sides
x=66.4
then, just plug in the numbers

You can buy 5 cans of green beans at the village market for $2.30, or you can buy 10 of them at Best Food for $5.10. Which place is the better buy?
Answer:
The village market
Step-by-step explanation:
Price per can at the village market
= 2.30÷5
= $0.46
Price per can at Best Food
=5.10÷10
= $0.51
Answer:
Village market
Step-by-step explanation:
Find the unit rate at village market and Best food and compare.
Village market:
Rate per can = 2.30 ÷ 5
= $ 0.46
Best food:
Rate per can = 5.10 ÷ 10
= 0.51
0.46 < 0.51
Buying can from village market is best buy as that is less priced
If a bike is going at 26 centimeters per second how many meters per minute is she traveling?
Answer:
15.6 meters in a minute
Step-by-step explanation:
Here's why:
1 centimeter= 0.01 meter
So, if you have 26 cm, that equals 0.26 meters.
Now, we know that there are 60 seconds in a minute.
So, we have to do 0.26 times 60 which equals 15.6 meters.
I hope this helps you! :)

The number of bacteria at the beginning of an experiment was 30 and the bacteria grow at an hourly rate of 1.4 percent. Using the model given by () = 0e, estimate the number of bacteria, rounded to the nearest whole number after 20 hours.
Answer:
The estimated number of bacteria after 20 hours is 40.
Step-by-step explanation:
This is a case where a geometrical progression is reported, which is a particular case of exponential growth and is defined by the following formula:
[tex]n(t) = n_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial number of bacteria, dimensionless.
[tex]r[/tex] - Increase growth of the experiment, expressed in percentage.
[tex]t[/tex] - Time, measured in hours.
[tex]n(t)[/tex] - Current number of bacteria, dimensionless.
If we know that [tex]n_{o} = 30[/tex], [tex]r = 1.4[/tex] and [tex]t = 20\,h[/tex], then the number of bacteria after 20 hours is:
[tex]n(t) = 30\cdot \left(1+\frac{1.4}{100} \right)^{20}[/tex]
[tex]n(t) \approx 39.616[/tex]
[tex]n(t) = 40[/tex]
The estimated number of bacteria after 20 hours is 40.

Compare 468,119 and 486,191
Answer:
468,119 < 486,191
Step-by-step explanation:
compare the left numbers. Four is equal to four, so go right. 6 is less than 8, so 468,119 < 486,191
In ΔABC, the measure of ∠C=90°, BC = 69 feet, and CA = 98 feet. Find the measure of ∠B to the nearest tenth of a degree.
The answer is 54.9
B=tan (98/69) B=54.8513 = 54.9
All irrational numbers are radicals.
True or false and why?
Here are some counter examples to disprove the original claim.
log(5) = 0.69897 ... where the log base is not any power of 5sin(27) = 0.45399pi = 3.14159e^3 = 20.0855369The decimal values are approximate.
All of those values are known as transcendental numbers. These are a class of numbers where we cannot write them as a root of some other number. It's similar to the idea how irrational numbers cannot be written as a ratio of two integers. All transcendental numbers are irrational, but not the other way around.
So in short, it is possible to have an irrational number where it's not a radical.
A cube has a volume of 125 square inches. What is the length of each edge?
