The answer would be the top left one because when dividing, you would subtract 8 from 13. I'm pretty sure not 100% though. Sorry.
A^2 + b^2 = c^2
4^2 + b^2 = 5^2
16 + b^2 = 25. -16
B^2 = 9
Square root of 9 = 3
B = 3
The other leg is 3cm
Answer:
Length of 6 feet
Width of 2 feet
The estimate of the perimeter of the countertop is 16 feet.
Step-by-step explanation:
Rectangle:
A rectangle has two dimensions: The length(l) and the width(w). The perimeter of a rectange is:
P = 2(l + w).
In this question:
Length: 5.75 feet
Width: 2.47 feet.
Round the length and width to the nearest whole number .
5.75 is closer to 6(0.25) than to 5(0.75). So the length is 6 feet.
2.47 is closer to 2(0.47) than to 3(0.53). So the width is 2 feet.
Then estimate the perimeter of the countertop
P = 2(l + w) = 2(6 + 2) = 16
The estimate of the perimeter of the countertop is 16 feet.
Answer:
half a batch
Step-by-step explanation:
half of half a lb is 1/4 therefore you can make one batch
Answer:
f(x)=−4(x+ 41 ) 2 − 4 11
Explanation:
The given function is
f(x) = - 4 {x}^{2} - 2x - 3f(x)=−4x 2 −2x−3
To write the function is vertex form, we need to complete the square.
We first factor -4 to get:
f(x) = - 4 ({x}^{2} + \frac{1}{2} x) - 3f(x−4(x2 + 21 x)−3
Add and subtract the square of half the coefficient of x.
f(x) = - 4( {x}^{2} + \frac{1}{2} x + \frac{1}{16} ) - \frac{1}{4} - 3f(x)=−4(x 2 + 21 x+ 16 1 )− 41 −3
We factor the perfect square trinomial and simplify to get:
f(x) = - 4( {x + \frac{1}{4} )}^{2} - \frac{11}{4}f(x)=−4(x+ 41 ) 2 − 4 11
