Answer:
[tex]y = 4(0.5) {}^{x} [/tex]
Step-by-step explanation:
By looking at your graph, The y intercept is (0,4).
This is an exponential function so it is represented by
[tex]y = ab {}^{x} [/tex]
where a is the vertical stretched and b is the constant rate and x is the nth power.
let plug in 0,4
[tex]4 = ab {}^{0} [/tex]
[tex]b {}^{0} = 1[/tex]
since anything to the 0 power is 1.
[tex]4 = a \times 1[/tex]
[tex]4 = a[/tex]
Know let plug it in to this equation.
[tex]y = 4b {}^{x} [/tex]
Let use 2,1 another point on the graph
[tex]1 = 4b {}^{2} [/tex]
Divide 4 by both sides
[tex]0.25 = {b}^{2} [/tex]
take sqr root of 0.25
[tex]0.5 = b[/tex]
So
the answer is
[tex]y = 4(0.5) {}^{x} [/tex]
An airplane can ascend at a rate of 54 1/2 meters in 2/3 of a second. How many meters can the airplane ascend in one second?
Answer:
The airplane ascends [tex]81\,\frac{3}{4}[/tex] meters in one second.
Step-by-step explanation:
Given that the airplane ascends [tex]54\,\frac{1}{2}[/tex] ([tex]\frac{109}{2}[/tex]) meters in [tex]\frac{2}{3}[/tex] seconds, we calculate the ascent rate of the airplane by simple rule of three:
[tex]x = \frac{\frac{109}{2}\,m }{\frac{2}{3}\,s } \times 1\,s[/tex]
[tex]x = \frac{327}{4}\,m[/tex]
[tex]x = 81\,\frac{3}{4}\,m[/tex]
The airplane ascends [tex]81\,\frac{3}{4}[/tex] meters in one second.

Answer:
There are 77 members in the group.
Step-by-step explanation:
1Rs = 100 paise ( Indian Currency Conversion )
Given,
Total amount collected is = Rs 59.29
Now convert Rs 59.29 to paise that is 59.29 × 100 = 5929 paise
Condition :- Paise collection = Total number of members
Consider any of the above condition as X
So, X² = 5929
X = √5929 = 77
Thus, Total number of members in the group is 77 [ Option C ]
Hope this helps you.
What number should be added to both sides of the equation to complete the square?
x^2-10x=12
Answer:
Step-by-step explanation:
x²-10x = 12
Coefficient of the x term: -10
Divide in half: -5
Square it: (-5)² = 5²
Add 5² to both sides:
x²-10x+5² = 12+5²
(x-5)² = 37
5 out of 40 randomly selected students at Oxford Middle School stated that they would like to have a school uniform policy. Based on those results, about how many students out of the 992 enrolled would you expect to want a school uniform policy?
Answer:
124
Step-by-step explanation:
5 out of 40 = ⅛ of the students stated they would like to have a school uniform policy.
992 × ⅛ = 124
A cement truck pours cement into a container in the shape of a cylinder with a radius of 4 feet. The height, h, of the cement in the container increases at a rate of approximately 10 inches per minute. Write an equation that models the volume, V, of the cement in the container in terms of h, then use the equation to determine the time at which the volume is 80π cubic feet. Note that the volume of a cylinder is V=πr2h, where r and h are the radius and height of the cylinder.

QUESTIONS ARE DOWN BELOW!!! ALL HELP WILL BE APPRECIATED AND I WILL TRY TO MARK BRAINLIEST (IF I CAN)
Answer: 90 and 110
Step-by-step explanation:
Mark is going to an awards dinner and wants to dress appropriately. He is running behind schedule and asks his little brother to randomly select an outfit for him. Mark has one blue dress shirt, one white dress shirt, one black dress shirt, one pair of black slacks, one pair of grey slacks, and one red tie. All six of his possible outfits are listed below. Let A AA be the event that Mark's little brother selects an outfit with black slacks and B BB be the event that he selects an outfit with a blue shirt. What is P ( A or B ) P(A or B)P, left parenthesis, A, start text, space, o, r, space, end text, B, right parenthesis, the probability that Mark's little brother selects an outfit with black slacks or an outfit with a blue shirt? Shirt Slacks Tie Outfit 1 11 Blue Black Red Outfit 2 22 Blue Grey Red Outfit 3 33 White Black Red Outfit 4 44 White Grey Red Outfit 5 55 Black Black Red Outfit 6 66 Black Grey Red
Answer:
The answer is "[tex]\bold{\frac{2}{3}}[/tex]".
Step-by-step explanation:
Pick a shirt first: 3 choices
Pick slacks next: 2 choices
Then choose a tie: 1 choice
Total: [tex]3 \times 2 \times 1 = 6[/tex] outfits.
These will be similarly divided between the two slacks, so 3 black slack outfits of [tex]6 = \frac{1}{2}[/tex]. Similarly, the 6 styles are also divided between the option of 3 shirts. 2 blue shirt outfits [tex]6 = \frac{1}{3}[/tex]
To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add [tex]\frac{1}{2} \ and \ \frac{1}{3}[/tex]. Add [tex]\frac{1}{2} \ and \ \frac{1}{3}[/tex], and remove the chance for both the black slack shirt and outfit and are one of the six outfits:
[tex]\to \frac{1}{2} + \frac{1}{3} -\frac{1}{6} =\frac{3+2-1}{6} =\frac{4}{6} = \frac{2}{3}[/tex]
Suppose $ 1,250 is placed in a savings account over 2 years. Find the interest earned if the rate is 4.5%
Answer: $112.50
Step-by-step explanation:
The Simple interest will be calculated using:
= Principal × Rate × Time
= 1250 × 4.5% × 2
= 1250 × 0.045 × 2
= $112.50
Therefore, the interest earned will be $112.50

a cyclist travels for 5 days and covers 375km in total.
He covers 67km 78km 46km and 89km on the fist 4 days .How far does he travel on day 5
Answer:
95km
Step-by-step explanation:
5 days = 375km
4 days = 67km + 78km + 46km + 89km= 280km
5 days - 4days = the 5th day
375km - 280km = 95km

How do we solve this?
Answer:
B is (3, 10)
Step-by-step explanation:
The midpoint of coordinates of the 2 points (x1, y1( and (x2, y2) is
(x1 + x^2) / 2 , (y1 + y2)/2.
So if (x, y) are the coordinates of B we have:
(7 + x)/2 + (2 + y)/2 = 5 + 6
So 7 + x = 2*5 so x = 3
AND 2 + Y = 12 SO y = 10.

The segment AB has the endpoints A(1,5) and B(3,2). The segment is translated 2 units down and 2 units right. What are the endpoints of the translated segment A'B'?
The endpoints of the translated segment A'B' after undergoing the given translation is; A'(3, 3) and B'(5, 0)
How to carry out translation transformation?In transformation in mathematics, there are different types such as dilation, reflection, rotation, translation e.t.c
Now, in this case what we are dealing with is translation which simply means moving an object or figure from one point to the other without changing the shape or dimensions.
To translate the point AB(x, y) , 2 units down and 2 units right, we will use the translation rule;
A'B'(x + 2, y − 2) .
We are given the coordinates of AB as A(1,5) and B(3,2)
Thus;
A'(1 + 2, 5 - 2) = A'(3, 3)
B'(3 + 2, 2 - 2) = B'(5, 0)
