Answer:
37/45 ≈ 0.822
Step-by-step explanation:
The formula for an exponential relation is ...
y = a·b^x
This question is asking for the value of b. It can be found by substituting the given values of x and y, and taking the ratio of the resulting equations.
90 = a·b^15
74 = a·b^16
Dividing the second equation by the first, we have ...
74/90 = (a·b^16)/(a·b^15)
74/90 = b
The decay factor is 74/90 = 37/45 ≈ 0.822
Answer:
37/45=0.822 this is my answer
Simplify the expression:
10 + 10j – 9
10+ 10 = 20j
20j- 9= 11
The answer is 11 or if in the quiz it is 11j

A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall
Answer:
57.14°
Step-by-step explanation:
A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall?
We solve the above question using the Trigonometric function of Sine
= sin theta = Opposite/Hypotenuse
Opposite = Length of the wall = 4.2m
Hypotenuse = Length of the ladder = 5m
Theta = Angle formed = x
Hence,
sin x = 4.2m/5m
x = arc sin(4.2m/5m)
x = arc sin(0.84)
x = 57.140119621°
Approximately = 57.14°

Answer:
[tex]\huge\boxed{C)\ 12}[/tex]
Step-by-step explanation:
The three interior angles in a triangle will always add up to 180°.
Therefore
[tex]59+(6x-10)+59=180\\(59+59-10)+6x=180\\108+6x=180\qquad|\text{subtract 108 from both sides}\\10-10+6x=180-108\\6x=72\qquad|\text{divide both sides by 6}\\\dfrac{6x}{6}=\dfrac{72}{6}\\\boxed{x=12}[/tex]
Answer:
Option C
The value of x is 12°
Step-by-step explanation:
Here, we know that in a Triangle The sum of all three angles is 180°.
Now,
59° + 59 + (6x - 10)° = 180°
118° + 6x - 10° = 180°
6x + 108° = 180°
6x = 180° - 108°
6x = 72°
x = 72° ÷ 6
x = 12°
Thus, The value of x is 12°

The table of values below represents an inverse variation relationship. what is the value of x when y= "3.25"?
X l Y
2 l 13
4 l 6.5
A. X=84.5
B. X=8
C. X=5.3
D. X=21.1
Using the constant of proportionality, the value of when y is 3.25 is 0.5 from the inverse variation.
What is inverse variation relationship?An rise in one variable causes a decrease in the other and vice versa in a mathematical relationship between two variables known as inverse variation, also known as inverse proportionality or inverse relationship. The following equation represents inverse variation:
y = k/x
In this equation, "y" and "x" stand in for the two variables, and "k" is the variational constant. Throughout the connection, the constant of variation has a set value that never changes.
Using the data given;
y = kx
Let's find the value of k;
k = constant of proportionality
13 = k(2)
k = 13/2
k = 6.5
Using the value of k;
3.25 = 6.5x
x = 3.25 / 6.5
x = 0.5
NB: The options given are incorrect and if you will follow through the steps, you will understand the options are incorrect.

-plug in earbuds or put on headphones, you dont have to play/listen to anything, but it helps block out noise
-maybe set a small goal for yourself, where if you get a class or quiz or whatever done, you go do something else that you enjoy for a few minutes and think of a new goal for the next class.
-sometimes actually playing music tends to help! at least to me
-it can be hard, but try your best to work on only your current assignment until your done with that one. nothing else.
-(if you do it at home) go into a silent room, like maybe yours, and close the door. take out anything that might distract you, like electronics.
-if you do this at home and use your computer/a computer and tend to go onto other websites for an hour instead of working, it might be best to ask someone to block those websites on your computer. thats the most major thing i can think of...

A recipe needs 4/5 cup of butter for every 2 cups of flour. If you plan to use 3 cups of flour, how much butter will you need?
Answer:
0.4 cups of flower (2/5)
Good luck!!
Answer:
1 1/5 cups
Step-by-step explanation:
Write and solve an equation of ratios here. Let x be the amount of butter needed if 3 cups of flour are used. Then, comparing the quantities of butter first (in the first column) and the quantities of flour second, we get the ratio
x 3 cups
------------- = -------------
(4/5) cup 2 cups
Cross-multiplying, we get:
2x = 12/5, or x = 6/5
You'll need 6/5 cups of butter, or 1 1/5 cups, if you're using 3 cups of flour.
The Gotemba walking trail up Mount Fuji is about 9 kilometres (km) long. Walkers need to return from the 18 km walk by 8 pm. Toshi estimates that he can walk up the mountain at 1.5 kilometres per hour on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi's estimated speeds, what is the latest time he can begin his walk so that he can return by 8 pm?
Answer:
He must start his journey by 11 AM
Step-by-step explanation:
Speed of Toshi while walking up the mountains is 1.5 kilometres per hour
Speed of Toshi while walking down the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour
Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours
Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours
He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance
Thus, He must start his journey by 11 AM
A parabola is defined as all points equidistant from a given directrix and focus true or false
False. A parabola is not defined as all points equidistant from a given directrix and focus.
A parabola is a conic section defined as the set of all points that are equidistant from a fixed point called the focus and a fixed line called the directrix. In other words, for any point on a parabola, the distance to the focus is equal to the perpendicular distance to the directrix. This property is known as the geometric definition of a parabola.
The focus and directrix are essential elements in defining a parabola, but they do not solely define it. The shape of a parabola is determined by the distance between the focus and the directrix. Varying this distance results in different sizes and orientations of parabolas.
The specific equation of a parabola incorporates the coordinates of the focus, the directrix, and a parameter called the focal length to precisely describe its form. False is the answer.
