The Coordinate of A is (0, 1) and the equation of the graph with B coordinate is ¹/₂^(ˣ) - (¹/₂)x
How to interpret Graph Functions?The equation of the accompanying graph is;
f(x) = aˣ
1) We want to write the coordinate of A. Thus;
f(0) = a⁰ = 1
Thus;
Coordinate of A = (0, 1)
2) The way we can tell that: 0 < a < 1 is; From figure number and inverse functions.
3) If B is the point (4, ¹/₁₆), then;
f(4) = a⁴ = ¹/₁₆
a = ⁴√(¹/₁₆)
a = ¹/₂
4) The equation of the graph with B coordinate is;
y - ax
⇒ ¹/₂^(ˣ) - (¹/₂)x
5) To get the coordinates of the point of intersection of the two graphs is;
¹/₂^(ˣ) - (¹/₂)x = ¹/₂^(ˣ)
⇒ (¹/₂)x = 0
x = 0
Thus, the coordinate of the intersection is; (0, 0)

A group of researchers want to determine whether type of psychotherapy has an effect on the number of PTSD symptoms in refugees. Specifically, they wan to determine if MDMA, a hallucinogenic drug given in a one-time dose, has a greater effect on reducing PTSD symptoms in refugees than the standard PTSD treatment or a placebo control. The researcher randomly assigns 60 people to 1 of the 3 treatment conditions. What is the alternative hypothesis in notation form? u1 =/ u2 =/ u3 p > 0 u1 = u2 = u3 It cannot be written in notation form.
The option u1 =/ u2 =/ u3 is correct if the researcher randomly assigns 60 people to 1 of the 3 treatment conditions.
What are the null hypothesis and alternative hypothesis?The null and alternative hypotheses are two generalizations about a population that are strictly contradictory. The null hypothesis can be denoted by H₀ and the alternative hypothesis can be denoted by H₁.
We have:

Rectangle QUAD has coordinates Q(0,0), U(0,), A(,), and D(,0). Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor . What are the coordinates of point D'?
The coordinates of point D' are (36,0).
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures.
QUAD has coordinates Q(0,0), U(0,3), A(6,3), and D(6,0).
The scale factor for Q'U'A'D' is 6.
So, the coordinates of Q'U'A'D' after dilation is:
Q'(0,0), U'(0,3*6), A'(6*6,3*6), and D'(6*6,0).
and Q'(0,0), U'(0,18), A'(36,18), and D'(36,0).
Hence, the coordinate of D' is (36,0).

Answer:
2.5 cups
Step-by-step explanation:
[tex]\frac{2}{12} =\frac{x}{15}[/tex] (x is the amount of cups of zucchini you will need to feed 15 people)
This proportion is showing that 2 cups of zucchini can feed 12 people, and we will use it to find how much zucchini we will need to feed 15 people.
Cross multiply
30 = 12x
divide both sides by 12 to isolate x

given 2 intersecting chords in a circle, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
FH × HG = DH × HE ( substitute values )
2y = 3 × 4 = 12 ( divide both sides by 2 )
y = 6
then
DE = 3 + 4 = 7
FG = 2 + y = 2 + 6 = 8
(b)
given 2 secants from an external point to a circle, then the product of one secant's external part and the entire secant is equal to the product of the other secant's external part and the entire secant , that is
AB × AC = AD × AE ( substitute values )
5(5 + x) = 6 × (6 + 6)
25 + 5x = 6 × 12 = 72 ( subtract 25 from both sides )
5x = 47 ( divide both sides by 5 )
x = 9.4
then
AE = 6 + 6 = 12
AC = 5 + x = 5 + 9.4 = 14.4

A brick layer can build a wall in 6 hours and his apprentice would need 16 hours to build the same wall. When they work together, the apprentice works 5 hours longer than the brick layer. How many hours does each work
Answer:
Step-by-step explanation:
The brick layer builds ( 1 wall ) / ( 6 hrs )
That's the same as ( 1/6 wall ) / ( 1 hour )
------------------------------------
The apprentice builds ( 1 wall ) / ( 16 hrs )
That's the same as ( 1/16 wall ) / ( 1 hour )
--------------------------------------
Let t = the time that the brick layer works
t + 5 = the timer the apprentice works
-----------------------------------------
( brick layer's rate ) x ( brick layer's time ) +
( apprentice's rate ) x ( apprentice's time ) = 1
( 1 is the whole job )
-----------------------------------------
(1/6) · t + (1/16) · (t + 5) = 1
Multiply both sides by 48
8t + 3t + 15 = 48
11t = 33
t = 3
t + 5 = 8
the brick layer works 3 hrs
The apprentice works 8 hrs
----------------------------
Check:
(1/6) · t + (1/16) · (t + 5) = 1
(1/6) · 3 + (1/16) · (3 + 5) = 1
1/2 + 1/2 = 1
