Answer:
$19.76
Step-by-step explanation:
First you turn the 15% to 0.15 and then you multiply it with $25 to get 3.75.
That isn't the meal though, but the discount you are going to get.
Now subtract 3.75 from 25 to get $21.25
After that multiply 21.25 with 7% which gets you 1.4875
Then, subtract 1.4875 from 21.25 to get 19.7625 which is rounded to $19.76
Answer:
<u>y'= 5x^4 + 5^x In(5)</u>
Step-by-step explanation:
<u>Differentiate</u><u> </u><u>with </u><u>Respect</u><u> </u><u>to</u><u> </u><u>x</u>
<u>f(</u><u>x)</u><u>'</u><u>=</u><u>5</u><u>x</u><u>^</u><u>4</u><u> </u><u>+</u><u> </u><u>In(</u><u>5</u><u>^</u><u>x</u><u>)</u>
<u>f(</u><u>x)</u><u>'</u><u>=</u><u> </u><u>5</u><u>x</u><u>^</u><u>4</u><u> </u><u>+</u><u> </u><u>x </u><u>In(</u><u>5</u><u>)</u>
<u>with </u><u>respect</u><u> </u><u>to </u><u>x,</u><u> </u><u>we </u><u>have</u>

Answer:
x=-1
Step-by-step explanation:
x^2+2x=16=0
Use the quadratic formula to find the solutions.
−b±√b2−4(ac)/
2a
Substitute the values
a=1, b=2, and c=−16 into the quadratic formula and solve for x
Answer:
The smallest side is 7inches
Step-by-step explanation:
Let the shorter side be y.
The medium side is 4 more than the short side i.e
Meduim side = 4 + y
The longest side is 5 times the length of the shortest side i.e
Logest side = 5y.
Perimeter of the triangle = 53 inches
But the perimeter of a triangle is the Sum of all sides i.e
P = small + medium + large
53 = y + (4+y) + 5y
53 = y + 4 + y + 5y
Collect like terms
53 — 4 = 7y
49 = 7y
Divide both side by 7
y = 49/7
y = 7inches
Therefore the smallest side is 7inches
