Reflection across the x-axis (because there is a negative)
And
Vertical compression (because a is between 0 and 1)
-25 is the correct answer
If Sheila started with 8 yards of fabric and used 2 1/4 yards, she will have the difference of these two values remaining. Subtract 2 1/4 from 8.
Convert the mixed fraction to an improper fraction. (Multiply its denominator by the whole number and replace the numerator with this new number.)
2 1/4 = 9/4
We now have:
8/1 - 9/4
Multiply 8/1 by 4/4 to get common denominators.
8/1 × 4/4 = 32/4
Now subtract.
32/4 - 9/4 = 23/4 = 5.75
Alternatively, we could have converted the fraction 2 1/4 to decimal form and subtracted it from 8.
2 1/4 = 2.25
8 - 2.25 = 5.75
Answer:
Sheila has 5.75 yards of fabric left.
Answer:
rationalizing
Step-by-step explanation:
Answer:
13.14
Step-by-step explanation:
sin 37.5 deg = 8/x
x = 8/sin 37.5 deg
x = 13.14
(I was thinking about it as a right angled triangle although the qn did not specify but idt you can solve it by using sine / cosine rule so TOA CAH SOH may be the only one and the most direct method to solve it)
