<span>y - k = a(x - h)²
</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²
</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.
Vertex (5,8).
First, let's make 1/2 and 3/7 have the same denominator to make it easier to see. We know that there Least Common Multiple (LCM) is 14.
1/2=7/14
3/7=6/14
Wait a second... 3/7 is less than 1/2. This means that Winnie's statement is false because it is impossible that after adding more flour, she actually has less flour than what she started with.
Hope this helps! :)
Help us out please I need this answer right answer too.
There's enough arithmetic involved in this that it is convenient to let a machine solver of some sort figure it out. Most graphing or scientific calculators will work this problem for you (consult the manual for yours). If you insist on doing it by hand, you must compute several average values:
• a1 = the average of sleep hours (h)
• a2 = the average of test scores (%)
• a3 = the average of the product of sleep hours and test scores (h×%)
• a4 = the average of the square of sleep hours (h×h)
a) The equation of your best-fit (least-squared-error) line is then
% = (a3 - (a1×a2))/(a4 - (a1)²)×(h - a1) + a2In numbers, this is
% = 6.33333h + 38.6875b) For h=8, the equation gives
6.33333×8 + 38.6875 ≈
89.4
Answer:
C 4.5 the two triangles in the diagram are similar.
Step-by-step explanation:
Since, the two triangles in the diagram are similar.
Therefore,
![4 \times x = 3 \times 6 \\ \\ x = \frac{18}{4} \\ \\ x = 4.5](https://tex.z-dn.net/?f=4%20%5Ctimes%20x%20%3D%203%20%5Ctimes%206%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B18%7D%7B4%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%204.5)
