Answer:
14
Step-by-step explanation:
<u>Find a number that is 4 more that is 4 more than 6 plus 4</u>
4 more than 6 plus 4
6 + 4 = 10
4 more means 4 + (6 +4)
= 14
Answer:
Step-by-step explanation:
SA = bottom rectangle area+side rectangle area + slant rectangle area + 2 triangles
= 26(36) + 10(36)+36(28) +2(0.5)(10)(26) = 2564 cm2
Step 1: convert the equation into fhe vertex form
To do you can complete squares:
y = - [x^2 + 4x + 3]
y = - [ (x + 2)^2 - 4 + 3]
y = - [ (x + 2)^2 - 1] = - (x+2)^2 + 1
Then the vertex is (-2, 1)
Now you can drasw the vertex
Step 2: Find the roots (zeros)
y = - [ (x + 2)^2 - 1] = 0
(x + 2)^2 - 1 = 0
(x+2)^2 = 1
(x+2) = (+/-) √1
x + 2 = (+/-1)
x = - 2 +/- 1
x = -1 and x = -3
Now you draw the points (-1,0) , (-3,0)
Step 3: find the interception with the y-axis.
That is y value when x = 0
y = - (0)^2 - 4(0) - 3 = -3
Then draw the point (0, -3)
Step 4: given that the coefficent of x is negative (-1) the parabola is open downward.
So, with those four points: vertex (-2,1), (-1,0), (-3,0) and (0,-3), you can sketch the function.
