Answer:
C
Step-by-step explanation:
Since the y-int. is 2 we know that the coefficient of the exponential term is 2, which eliminates B and D. Since f(x) decreases from left to right, the number in the parentheses has to be less than 1, so the answer is f(x) = 2 * (0.25)^x.
Answer: C.f(x)=2•(0.25)^x

Suzan bought some balloons and repacked them for sale. He threw away 76 balloons each. Each packet was sold at $86. After selling all the packet of balloon he collected $9,632 altogether. How many balloons did Suzan buy? A.1,644 B.1,464 C.1,466 D.1,646
Answer:
188 balloons
Step-by-step explanation:
First, we have to divide the amount he collected altogether by the price of each balloon that he sold to find out how many balloons he sold:
9632 / 86 = 112 balloons
She sold 112 balloons.
We know that she threw 76 balloons away, therefore, the number of balloons she bought was:
112 + 76 = 188 balloons
Which equations are equivalent to Negative one-fourth (x) + three-fourths = 12 Select all that apply.
(StartFraction negative 4 x over 1 EndFraction + three-fourths = 12

how to solve this problem
Answer:
PR = 180 cm
Step-by-step explanation:
Given PQ : QR = 7 : 3 = 7x : 3x ( x is a multiplier )
PQ - QR = 72, substitute values
7x - 3x = 72
4x = 72 ( divide both sides by 4 )
x = 18
Thus
PR = PQ + QR = 7x + 3x = 10x = 10 × 18 = 180 cm
Answer:
180
Step-by-step explanation:
PQ:QR= 7:3
PQ-QR=72
7x- 3x= 724x= 72x= 72/4x=187x= 126, 3x= 3*18= 54PQ= 126 cm, QR= 54 cm
PR= PQ+QR= 126+54= 180 cm

Answer:
Length of wire is required = 840 cm
Step-by-step explanation:
Given:
20 by 20 grid
Find:
Length of wire is required.
Computation:
We know that 20-20 grid required 21 lines.
20 cm vertical and horizontal.
⇒ Length of wire is required = (21 + 21)20 cm
⇒ Length of wire is required = (42)20 cm
⇒ Length of wire is required = 840 cm

Which of the following explains why Cosine 60 degrees = sine 30 degrees using the unit circle?
The answer is: The side opposite a 30° angle is the same as the side adjacent to a 60° angle in a right triangle. On a unit circle, the (sin) distance of a 30° angle is the same as the x (cos) distance of a 60° angle.
But I would really appreciate someone to explain this to me, thank you!
Answer:
Step-by-step explanation:
Suppose triangle CAD with A = 60^0 and triangle ABE with B = 60^0. They are similar (the order matter, don't change the order)
We have CD = AE and AD = BE , AC = AB (radius)
in triangle CAD, cos A = cos (60) = AD/ AC
in triangle ABE, sin A = sin (30) = BE/AB
We have denominators are equal (both are radius of the circle) and numerator are equal, that gives cos (60) = sin (30)
Answer:
The side opposite a 30° angle is the same as the side adjacent to a 60° angle in a right triangle. On a unit circle, the y (sin) distance of a 30° angle is the same as the x (cos) distance of a 60° angle.

Frankie wants to build a path from one corner of his yard to the opposite corner. His yard measures 20 ft. x 32 ft. What will be the length of his path to the nearest tenth of a foot?
Answer:
≈37.7 feet
Step-by-step explanation:
I'm assuming he goes diagonally.
We can form a triangle with legs 20 feet and 32 feet.
Using the Pythagorean Theorem, we get:
[tex]20^2+32^2=c^2\\400+1024=c^2\\1424=c^2\\c^2=1424\\c=\sqrt{1424}\\[/tex]
c≈37.7
Answer: 37.7 ft
Step-by-step explanation:
20^2 + 32^2 = C^2 where c squared is the distance of the diagonal distance that he wants to walk.
20^2 +32^2 =c^2
400 +1024 =c^2
1424 = c^2
c= 37.7359 rounded to the nearest tenth of a foot is 37.7

3(x - 2) + 2 = 5(x - 3) + 9 por fa
Answer:
x = 1
Step-by-step explanation:
Given
3(x - 2) + 2 = 5(x - 3) + 9 ← distribute and simplify both sides
3x - 6 + 2 = 5x - 15 + 9
3x - 4 = 5x - 6 ( subtract 5x from both sides )
- 2x - 4 = - 6 ( add 4 to both sides )
- 2x = - 2 ( divide both sides by - 2 )
x = 1

Which of the following could be f(x)?
Answer:
f(x) = -2x² + 2
Step-by-step explanation:
If you remember the y = x² parent graph, you will be able to derive your equation from visualization.
The vertex of this graph would be at (0, 2), so your degree coefficient would be negative. Your y-intercept would also be at (0, 2). Since both 1 and -1 are included, you can tell it is a parabola, and hence the 3rd option is your answer.
what types of correlation would be expected between distance run and calories burned? would this relationship be casual - positive correlation, not casual - positive correlation, casual - negative correlation, not casual - negative correlation, casual
Answer:
It's the first choice - causal, positive correlation.
Step-by-step explanation:
The further you run the more calories you will burn so there is a positive correlation here.
The relationship between distance run and calories burned is generally expected to be causal and positive, but it may be influenced by various individual and contextual factors.
Here, we have,
The relationship between distance run and calories burned is expected to exhibit a causal - positive correlation. This means that as the distance run increases, the calories burned are also expected to increase. The more someone runs, the more energy they expend, leading to a higher calorie burn.
However, it's important to note that while this relationship is expected to be causal and positive, there can be individual variations. Factors such as an individual's weight, metabolism, running efficiency, and other physiological factors can influence the calorie burn. Additionally, other factors such as running speed, terrain, and intensity of the run can also affect the relationship.
In summary, the relationship between distance run and calories burned is generally expected to be causal and positive, but it may be influenced by various individual and contextual factors.

p inversely as( m + 1 ). when p = 4, m = 8 . (a)Find a equation connecting P and ( m + 1 ). (b)calculate the value of p when m = 11
Answer:
a. p= 36/(m + 1)
b. p = 3
Step-by-step explanation:
If p varies inversely as (m + 1)
then p = k × 1/(m + 1). {Where k is the constant}
when p = 4, m = 8, that means 4 = k/(8 + 1)
4 × 9 = k and k = 36
a. Therefore the equation is p= 36/(m + 1)
b. When m = 11,
p = 36/(11 + 1)
p = 36/12
p = 3
Triangle ABC has perimeter 20 cm.
AB = 7 cm.
BC = 4 cm.
By calculation, deduce whether triangle ABC is a right-angled triangle.
Answer:
You have an obtuse, scalene triangle, so no :)
Step-by-step explanation:
Side a = 4
Side b = 9
Side c = 7
Angle ∠A = 25.209° = 25°12'32" = 0.43998 rad
Angle ∠B = 106.602° = 106°36'6" = 1.86055 rad
Angle ∠C = 48.19° = 48°11'23" = 0.84107 rad
Answer:
Triangle ABC is not a right-angle triangle.
Step-by-step explanation:
perimeter of the triangle: 20cm
AB=7cm and BC=4cm.
We can do the third length (AC) by subtracting the known lengths from the perimeter: 20 - 7 - 4 = 9
Therefore, the length AC is 9.If
ABC were a right angle triangle, we'd be able to use Pythagoras's Theorem to work out the length AC.
AC is the hypotenuse of the triangle because it is the longest length.
a2 + b2 = c242 + 72 = 16 + 49 = 65
Where AC = c, c2 = 65 If c = 9, then c2 = 81, however when using Pythagoras, c2 = 65.
