A
Step-by-step explanation:
Equation
300 ( 1 + x) = 420
Explanation
You start with 300. What fractional amount do you need to increase the original amount up to 420
Solution
Divide both sides by 300
300(1 + x)/300 = 420/300
1 + x = 1.4
Subtract 1 from both sides.
1 - 1 + x = 1.4 - 1
x = 0.4
But as a percent this number is 0.4 * 100 = 40%
Answer
40% which is A
Hello there!
Knowing that the vertex form of the quadratic equation is
y=a(x-h)^2+k where (h,k) represents the vertex, and the a value represents the leading coefficient of the quadratic equation in standard form, first plug in your known values (your given coordinate point can be plugged into the x and y values, and your given vertex can be plugged into h and k):
-4=a(0-10)^2-9
Because your a value is still unknown, you can use your given values in the equation to solve for a:
-4=a(-10)^2-9
-4=100a-9
100a=5
a=1/20
Now that you have your a value, you can plug it into your vertex form as well as your vertex values to get that your equation in vertex form is:
y=1/20(x-10)^2-9
The answer would be 1/6 of cake.

Step-by-step explanation:
Ascending Order:
When we talk about the numbers to be arranged in ascending order, it means the numbers need to be arranged from smallest to largest.
For example, if we have to arrange the numbers from 1 to 5 in ascending order.
It means, the ascending order will be: 1, 2, 3, 4, 5
Now, let us arrange the given numbers in ascending order.
a) 2234 to 2238 2234 2235 2236 2237 2238
b) 4099 to 4103 4099 4100 4101 4102 4103
c) 3298 to 3302 3298 3299 3300 3301 3302
d) 7269 to 7273 7269 7270 7271 7272 7273
e) 6354 to 6358 6354 6355 6356 6357 6358
f) 8379 to 8383 8379 8380 8381 8382 8383
g) 7365 to 7369 7365 7366 7367 7368 7369
