Answer:
26. B(t) = 500·1.075^t; B(6) ≈ $772
27. G(t) = 70·0.72^t; G(3) ≈ 26 g
Step-by-step explanation:
The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.
__
26. B(t) = 500·1.075^t
B(6) = 771.65
The balance after 6 years is about $772.
__
27. G(t) = 70·0.72^t
G(3) = 26.127
About 26 grams are left after 3 days.
PLEASE HELP PLEASEEEE!!! Number 3
Please help!!! I can't answer this!!!!
Answer:
y=8x
Step-by-step explanation:
X is the input, Y is the output. The answer describes that whatever X is, if you times it by 8, you get Y. It can't be "x + 14" because that only works with the first number given. If you do Y = X + 14, 6 doesn't equal 48.

Complete the equation of the line through (-6, 5) and (-3, -3)
Answer:
y = -8/3x - 11
Step-by-step explanation:
(-6, 5) and (-3, -3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-5)/(-3+6)
m=(-8)/3
m= -8/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -8/3(x + 6)
y - 5 = -8/3x - 16
y = -8/3x - 11
5x + 8 =33 what is the x

What would be the first step in solving the equation 7/9x + 34 = 174?
Answer:
[tex] \frac{7}{9} x + 34 = 174 \\ => \frac{7x}{9} = 174 - 34 \\ = > \frac{7x}{9} = 140 \\ = > 7x = 140 \times 9 \\ = > 7x = 1260 \\ = > x = \frac{1260}{7} = 180 \\ { \huge{ \pink{x = 180}}}[/tex]

Write the equation of the graph in slope intercept form
Answer:
1/2x+3
For the slope you have to on the 2,2 you have to go up and over to the next dot on a line and for the y intercept you just have to find it on the line and if it was on the bottom do a -3 rather than a +3.
Solve to find the answer of blue pills Mr body took: number of blue pills, b, mr mattics give him was 3 more than the number of green pills,g, total number of pills took was 17, 11 blue pills to kill
Answer:
Mr body took 9 blue pills
Step-by-step explanation:
Total number of pills consumed = 17
Number of blue pills, b = 11
Number of blue pills, b = g + 3
So that,
b = g + 3
11 = g + 3
g = 8
Total number of pills recommended = b + g
= 11 + 8
= 19
Total number of pills consumed = 17
Thus,
Number of blue pills consumed = 17 - 8
= 9
Therefore, Mr body took 9 blue pills.
what is the answer for 9k^2=225
9k² = 225
k² = 225 : 9
k² = 25
k = -5 and k = 5 because :
(-5)² = (-5) * (-5) = 25
5² = 5 * 5 = 25

You are a laboratory technician. You are filling spherical flasks with a salt solution and then putting them into boxes. Each flask has a volume of 113.04 cubic inches.
Rounded to the nearest tenth of an inch, what is the radius of one flask?
3.0
3.6
5.2
6.4
6.9
Answer:
3.0 inches
Step-by-step explanation:
The formula for the volume of a sphere is
V = 4/3 × π × r³
V = 113.04 cubic inches
To find r
r = (3V/4π)⅓
r = (3 × 113.04/4 × π )⅓
r = 3.0 inches
The radius of one flask = 3.0 inches
Option A is correct

A soccer player is 30 feet from the goal line. He shoots the ball directly at the goal.
The goal is 8 feet high. What is the maximum angle of elevation at which the player
can shoot the ball and still score a goal?
Answer:
14.93°
Step-by-step explanation:
Using trigonometry :
From the diagram attached :
Angle of elevation = x
To obtain the value of x
Tan x = opposite / Adjacent
Tan x = 8 / 30
Tan x = 0.266666
x = tan^-1(0.26666)
x = 14.93°
Therefore, the angle of elevation is 14.93°

Find the area of the parallelogram
Answer:
A=32
Step-by-step explanation:
area of parallelogram formula
A=b*h
A=8*4
A=32
Answer:
32
Step-by-step explanation:
Intuition for why the area of a parallelogram is A = b h A=bh A=bh. The formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle.
A=bh=8·4=32

Plz help!!! You identify the error the solve it correctly!!!!!
Answer:
You have to multiply the numbers diagonally not vertically.
So
10x = 7(350)
10x = 2450
x = 245
9514 1404 393
Answer:
different sides of the equation were multiplied by different numbersx = 245Step-by-step explanation:
There is a method of solving proportions that is called "cross multiply" or "cross multiplication". For a proportion like this it looks like each numerator is multiplied by the opposite denominator. In this problem, the result would be ...
7(350) = (10)x
While "cross multiplication" is a description of the appearance of what is happening, what is really happening is that both sides of the equation are being multiplied by the same value: the product of the denominators. This is in accordance with the multiplication property of equality, which requires you multiply both sides of the equation by the same value.
__
The error that was made in this problem is that each numerator was multiplied by its own denominator. Effectively, that multiplied the left side of the equation by 10² = 100, and the right side of the equation by 350² = 122500. This is in direct violation of the multiplication property of equality, so guarantees the value found for x will be wrong.
__
While "cross multiply" is an instruction often given for solving proportions, it causes an extra step to be needed in solving a proportion like this one. All that is really needed is to multiply both sides of the equation by the denominator under the variable. Here, that means multiplying both sides of the equation by 350.
Correct solution
[tex]\dfrac{7}{10}=\dfrac{x}{350}\\\\350\cdot\dfrac{7}{10}=350\cdot\dfrac{x}{350}\\\\\\35\cdot 7=\boxed{x=245}[/tex]

X2-6x+8=? Answer plzzzzzzzzzzzzzz
Answer:
The answer to your problem should be 2
Answer:
x^2 - 6x + 8 = x^2 - 2x - 4x + 8 = x(x-2) - 4(x-2) = (x-4) (x-2)
x - 4 = 0 => x = 4
x - 2 = 0 => x = 2

Answer:
22
Step-by-step explanation:
Hey There!
So if you didn't know angle H is a right angle. So we are given two angles and they want us to find the missing angle
Remember all of the angles of a triangle add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-90-68=22
so we can conclude that angle G = 22
