Slope is the rise over the run. In other words, the difference in y values divided by the difference in x values. Start at the bottom corner of the roof and count the tiles upwards until you get to the top tip of the roof. It should be 4. Now from that point, count over to the right until you are at the top. It should be 5.
So the slope is 4/5 or 0.8.
Answer:
The correct option is;
C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2
Step-by-step explanation:
The area of the square frame is the area of the inner square subtracted from the area of the outer square
Which gives;
52.2² - 47.8² = 440
Therefore;
Option A. 52.2² - 47.8² is a correct way of finding the area of the square frame
Option B. 2 × ((52.2×2.2) + (47.8×2.2)) = 440, is a correct way of finding the area of the square frame
Option C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2 = 880, is not a correct way of finding the area of the square frame
The error is the thickness is 2.2 not 4.4
Option D. 100×(52.2 - 47.8) = (52.2 + 47.8) × (52.2 - 47.8) = 52.2² - 47.8² = 440, is a correct way of finding the area of the square frame
0.2 × 10
Move the decimal point one place to the right and you will get 2, NOT 0.02.
Therefore this statement is <em>false</em>.
We answer the question by substituting 5 to all the x's of the given function,
f(x) = 2x² + 2
Substituting,
f(5) = 2(5²) + 2 = 52
Thus, the f(5) is equal to 52. The answer is letter B.
Answer:
7a^4 +35a^2 +28a
Step-by-step explanation:
Area is the product of height and width:
area = height × width
= 7 × (a^4 +5a^2 +4a)
area = 7a^4 +35a^2 +28a . . . . . . use the distributive property
