Answer:
h = -25.2
Step-by-step explanation:
To solve the equation, you want to isolate the h variable. To do this, move 12.6 to the other side of the equation. Since you were adding on the left side, use the inverse operation, subtracting, on the right. Simplify the result to get the answer.
h + 12.6 = -12.6
h = -12.6 - 12.6
h = -25.2
s = ut + 1/2at squared
u = 10 a = -2 t = 1/2
Answer: 4.75
with u = 10, a = -2, t = 1/2
=> [tex]s=10.\frac{1}{2}+\frac{1}{2}. \frac{(-2).1}{4}=5-\frac{1}{4}=\frac{19}{4}=4.75[/tex]

A scientist measures the temperature of a chemical solution. At the start of the experiment, the solution is at a temperature of -14.06*C. TH decreases 2.9°C each hour. What is the temperature of the solution after 3 hours, rounded to the nearest whole degree?
Answer:
T(3) = -23°C
Step-by-step explanation:
Constant Rate of Change
Given an initial condition of a variable T, To and a constant rate of change m, it's possible to write a model to predict the value of T in time t:
[tex]T(t)=T_o+mt[/tex]
The initial temperature the scientist measures of a chemical solution is To=-14.06°C.
It's known the temperature decreases at a constant rate of -2.9°C each hour, thus the model is:
[tex]T(t)=-14.06-2.9t[/tex]
Evaluating at t=3 hours:
[tex]T(3)=-14.06-2.9\cdot 3[/tex]
[tex]T(3)=-14.06-8.7[/tex]
T(3) = -22.76°C
Rounding to the nearest whole degree:
T(3) = -23°C

Actually Welcome to the Concept of the Straight lines.
Since there are more than one lines that can land plane safely, we take one of it,
When, X = 10 and Y = 7, so the equation we get as,
y-7 = m(x-10) + c
lets find slope, that is value of m,
y2-y1/x2-x1 = m
so, 9-7/ 7-10 = 2/-3
so, m= -2/3
so the final Equation is,
=> y-7 =(-2/3)(x-10) +c

Answer:
x=3
Step-by-step explanation:
The triangle has angles 30,60,90
In this type of right triangle, the ratio of the sides is 1:square root of 3:2
In this type of triangle, the square root of 3 is equal to the 1 in the ratio above because it is across from the angle 30
With this, we multiply the ratio at the top by the square root of 3
since x is across the angle 60, we multiply square root of 3 by the square root of 3 which equals 3.
I hope this makes sense

Point Form: ( 4 , − 5 )
Equation Form: x = 4 , y = - 5
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: ( 4 , − 5 )
Equation Form: x = 4 , y = - 5
Answer:
(4, - 5)
Step-by-step explanation:
3x - 4y = 32 ........ (1)
5x + 2y = 10 ....... (2)
(2) × 2 + (1)
13x = 52 ⇒ x = 4
3(4) - 4y = 32 ⇒ y = - 5

The LA Dogers hit the most home runs in 2014. The number of home runs accounted for 6% of the entire major league Baseball home run count.If 583 total home runs were hit, then how many did the LA Dogers hit
Given:
Total number of home runs = 583
Home runs hit by LA Dogerse = 6% of the total home runs
To find:
The number of home runs hit by LA Dogers.
Solution:
We have,
Home runs hit by LA Dogerse = 6% of the total home runs
[tex]=\dfrac{6}{100}\times 583[/tex]
[tex]=\dfrac{3498}{100}[/tex]
[tex]=34.98[/tex]
[tex]\approx 35[/tex]
Therefore, LA Dogerse hits about 35 home runs.

A student collected monetary pledges for a fundraiser. One donor pledged to contribute $5 for each mile walked by the student during the fundraising walk up to a maximum of six miles.
A. is the situation continuous or discrete
B.write the domain and range of the situation
Answer:
A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Step-by-step explanation:
A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.
B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.
{ x : 0 ≤ x ≤ 6; x ∈ Z}
ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.
{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Isabella pitches for her high school softball team. Of the 7 pitches she throws, 5 are strikes. She uses a standard deck of cards to model her pitches, with hearts, clubs, and spades representing strikes. Which statement about her model is true?
A- Her model can be improved the most by removing all the face cards from the deck. B-Her model cannot be improved. C-Her model can be improved the most by removing all the aces from the deck. D-Her model can be improved the most by removing the queens and kings of hearts, clubs, and spades.
Answer:
B. Her model cannot be improved.
Step-by-step explanation:
We make this conclusion because it seems Isabella's model isn't actually proffering any solution to increase/reduce the number of strikes she has had.
Hence, any changes made do not clearly seem to improve the present model she is using.

Xavier ran 2.5 miles in 12 minutes. How long will it take him to run 1 mile?
Answer:
4.8 minutes
Step-by-step explanation:
2.5/2.5=1
so
12/2.5=4.8
Answer:
4.8 minutes per mile
Step-by-step explanation:
Let mi be miles
Let min be minutes
2.5mi = 12min
Divide by side by the mile to get the unit rate
2.5/2.5 = 12/2.5
You will get 1 = 4.8
Find an explicit rule for the nth term of the sequence.
-4, -8, -16, -32, ...
A) an = -4 • 2n - 1
B) an = 2 • -4n + 1
C) an = 2 • -4n
D) an = -4 • 2n
Answer:
An explicit rule for the nth term of the sequence will be:
[tex]a_n=-4\cdot \:2^{n-1}[/tex]
Thus, option (A) is true.
Step-by-step explanation:
Given the sequence
[tex]-4, -8, -16, -32, ...[/tex]
A geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_0\cdot r^{n-1}[/tex]
Computing the ratios of all the adjacent terms
[tex]\frac{-8}{-4}=2,\:\quad \frac{-16}{-8}=2,\:\quad \frac{-32}{-16}=2[/tex]
As the ratio 'r' is the same.
so
[tex]r=2[/tex]
as
[tex]a_1=-4[/tex]
Hence, the nth term of the sequence will be:
[tex]a_n=a_0\cdot r^{n-1}[/tex]
substituting the values [tex]r=2[/tex] and [tex]a_1=-4[/tex]
[tex]a_n=-4\cdot \:2^{n-1}[/tex]
Therefore, an explicit rule for the nth term of the sequence will be:
[tex]a_n=-4\cdot \:2^{n-1}[/tex]
Thus, option (A) is true.

if kevin took 1/10 of an hour to use 1/2 of package of napkins. how many hours would it take to use 2 packages?
Answer:
2/5 hours
Step-by-step explanation:
We can write a proportion to solve
1/10 hour x hours
---------------- = -------------------
1/2 package 2 packages
Using cross products
1/10 * 2 = 1/2 x
1/5 = 1/2x
Multiply each side by 2
1/5 * 2 = 1/2x *2
2/5 =x
2/5 hours
Explain what is occurring in each chunk of the graph
Answer:
Please check the explanation.
Step-by-step explanation:
As the given graph includes distance 'd' at the y-axis and time 't' at the x-axis.
so from the distance-time graph, it is clear that the graph includes 5 chunks.
The first chunk of the graph indicates that the object has started traveling. And the distance 'd' is being covered in time 't', as the slope is upward, hence the speed of the object is increasing.
Please note that speed is basically the distance covered per unit time.The second chunk of the graph indicates the no distance is being covered. It means the object is at rest.
The third chunk of the graph indicates that the distance 'd' is being covered in time 't', as the slope is again upward, hence the speed of the object is increasing and the object has started traveling.
The fourth chunk of the graph indicates that the slope is downward, and the object has started traveling to get back to the destination, and eventually, the object has reached the starting point.
