1. Which quadratic has a maximum?
a. y=x2+2x+2
b. y=-2x2 – 3x+5 I
y = 0.5(x – 3)2 +1
d. y = 2x + x2 - 11
Answer:
B
Step-by-step explanation:
A quadratic has a maximum value when its leading coefficient is negative, as the parabola will be curving downwards.
For A, we have the function [tex]y=x^2+2x+2[/tex]
The leading coefficient here is 1, which is positive. So, A has a minimum value.
For B, we have the function [tex]y=-2x^2-3x+5[/tex]
In this case, the leading coefficient is -2, which is negative. So, B is curving downwards. Therefore, it has a maximum value.
Hence, B is our correct answer.
For C and D, the leading coefficient of C is 1/2 (coefficient in front of the parentheses) and the leading coefficient of D is 1 (coefficient of the squared variable). Since both are positive, both C and D have a minimum.

What is the graph of 4x + 8y = 16?
Answer: Slope: -1/2 y-intercept: 2
Step-by-step explanation:
Subtract 4 x from both sides of the equation. 8 y = 16 − 4 x Divide each term by 8 and simplify. Divide each term in 8 y = 16 − 4 x by 8 . 8 y 8 = 16 8 + − 4 x 8 Cancel the common factor of 8 . Tap for fewer steps... Cancel the common factor. 8 y 8 = 16 8 + − 4 x 8 Divide y by 1 . y = 16 8 + − 4 x 8. y=2−x2. The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept. y = m x + b Reorder 2 and − x 2 . y = − x 2 + 2. Rewrite in slope-intercept form. y = − 1 2 x + 2.Slope:−1/2 y-intercept:2

(-4,6), slope=-1
Write the slope-intercept equation using the given information.
Answer:
y = -x +2
Step-by-step explanation:
y = mx + b
y=6
x=-4
m=-1 (m is the slope)
b=? (b is the y-intercept)
Putting these numbers into this equation,
6 = -1(-4) + b
b=6-4
b=2
So the equation is y = -1x + 2
or just y = -x +2

AAS postulate of congruence is:
two triangles are congruent if 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd ΔIn the given figure
∵ JKL and JML are two triangles
∵ ∠K and ∠M are right angles
∴ ∠K ≅ ∠M
∵ ∠JLK and ∠JLM have the same mark
∴ ∠JLK ≅ ∠ JLM
∵ JL is a common side in the 2 triangles
∴ JL = JL
→ BY using the AAS postulate above
∴ ΔJKL ≅ ΔJML
→ From the result of congruency
∴ JK = JM
∵ Jk = 2x - 4
∵ JM = 4x - 16
→ Equate them
∴ 4x - 16 = 2x - 4
→ Subtract 2x from both sides
∴ 4x - 2x - 16 = 2x - 2x - 4
∴ 2x - 16 = -4
→ Add 16 to both sides
∵ 2x - 16 + 16 = -4 + 16
∴ 2x = 12
→ Divide both sides by 2
∴ x = 6

from a boat on the lake the angle of elevation to the top of a cliff is 18°41’. if the base of the cliff is 991 feet from the boat how high is the cliff (to the nearest foot)
Answer:
The cliff is 335 feet tall.
Step-by-step explanation:
First you convert the angle to degrees and you get 18.683 degrees.
Then you set up the equation where x is the height of the cliff.
Tan(18.683) = (x/991)
Then you solve for x and you get 335 ft when your ound to the nearest whole number.
The cliff is 355 feet high.
What is Trigonometry?Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
We have angle of elevation to the top of a cliff is 18°41’.
First, convert the angle to degrees
= 18°41’
= 18.683 degrees.
let x is the height of the cliff.
Using Trigonometry
tan(18.683) = (x/991)
x = 335 ft
