Point slope formula: y-y1=m(x-x1). Answer: y-7=6(x-(-4))
Answer:
k = log9 / log 0.66
k = 5.3
Step-by-step explanation:
Please always remember that, when an exponential equation is given with different bases, the best approach is to take log of both sides.
If you have a calculator handy, that would be pretty fast and easy.
0.66 ^ k = 9
Take log of both sides:
klog 0.66 = log 9
k = log 9 / log 0.66
k = 0.954 / - 0.18
k = -5.3
Maths is fun, let's keep learning
Replace x by 4
F(4)= 19(4)+10
F(4)=76+10
F(4)= 86
Hope this helps!!
Slope intercept form is y = mx + b.....so lets solve for y
9x - 7y = -7 .....subtract 9x from both sides
-7y = -9x - 7...now we divide both sides by -7
y = 9/7x + 1 <==
Answer:
<h2>25 mph</h2>
Step-by-step explanation:
<h3>
Step 1: Convert miles to feet</h3>
First, we need to convert the miles to feet keeping in mind that:
1 mile = 5,280 feet
655 ft 19 sec
5,280 ft 4 min 24 sec
<h3>Step 2: Divide the distance by the time to find the unit rate</h3>
3,447 feet per minute
1,245 feet per minute
<h3>Step 3: Convert minutes to hours</h3>
206,820 feet per hour
74,700 feet per hour
<h3>Step 4: Convert feet to miles</h3>
39.17 miles per hour
14.15 miles per hour
To find how much faster Michael ran, we need one more step.
<h3>Step 5: Subtract smaller amount from larger amount</h3>
39.17 - 14.15 = 25
I'm always happy to help :)
