Answer:
12,16,20
Step-by-step explanation:
because in Pythagoras theorem m/2
Answer:
(D)3 units
Step-by-step explanation:
To find the value of a, we use the Theorem of Intersecting Secants.
Applying this to the diagram, we have:
UV X TV = RV X SV
12 X a=(5+4)*4
12a=9*4
12a=36
Divide both sides by 12
a=3 units.
<u>The correct option is D.</u>
Answer:
-11/24
Step-by-step explanation:
5/12 - 7/8
We need to get a common denominator of 24
5/12 *2/2 - 7/8 *3/3
10/24 - 21/24
-11/24
Answer:
D
Step-by-step explanation:
Given
- (x + 3) - 2(4x - 3) ← distribute both parenthesis
step 1
= - x - 3 - 8x + 6 ← collect like terms
step 2
= - 9x + 3
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.
