Martin says that f(x)=2(4)^x starts at 4 and has a constant ratio of 2. What error did Martin make? Explain.
Answer:
A general exponential equation is written as:
f(x) = A*(r)^x
Where:
A is the initial value, this is the value that the function takes when x = 0.
r is the rate of growth
x is the variable.
In this case, the function is:
f(x) = 2*(4)^x
The initial value is:
f(0) = 2*(4)^0 = 2*1 = 2
The initial value is 2.
And the rate of growth is 4.
So Martin seems to mixed these two values (he said initial value = 4, and rate = 2, which is the opposite of what we found)
What is the value of x?
Answer:
x = 21
Step-by-step explanation:
ALL triangles add up to 180 degrees
180 = 22 + 57 + (5x - 4)
180 = 79 + (5x - 4)
101 = 5x - 4
105 = 5x
21 = x

Step-by-step explanation:
PLEASE HELP ME A soccer field is bordered on three sides by a parking lot of width x. The total length of the field and parking lot is 300 m, and the total width is 200 m.
The area of the field is 30.000 m². How wide is the parking lot?
Answer:
Step-by-step explanation:
Assuming the parking lot is along both widths of the field and only once along the length:
the length is (300 - 2x)
the width is (200 -x)
the area is (300-2x)(200-x) = 30000
60000 -300x - 400x +2x^2 = 30000
2x^2 -700x + 30000 = 0
x^2 - 350x + 15000 = 0
(x - 300 )(x - 50 ) = 0
x = 300 or x=50
x=300 results in negative measures.
the parking lot is x=50 wide
the length of the field is 200, the width of the field is 150

x = angle left of (4x+5) [ᴄᴏʀʀᴇsᴘᴏɴᴅɪɴɢ ᴀɴɢʟᴇs]
So, x + (4x+5) =180° [sᴜᴘᴘʟᴇᴍᴇɴᴛᴀʀʏ ᴀɴɢʟᴇs]
[tex](4x + 5 )+ x = 180 \\ 4x + 5 + x = 180 \\ 5x + 5 = 180 \\ 5x = 180 - 5 \\ 5x = 175 \\ x = \frac{175}{5} \\ x = 35[/tex]

Answer:
d) [tex](9*3/4)+y[/tex]
Step-by-step explanation:
b) [tex]9+y*(3/4)[/tex]
This expression is not equivalent, as the original expression, [tex]y+9*\frac{3}{4}[/tex] , has 9 multiplied to [tex]\frac{3}{4}[/tex] instead of y. You can interchange values like this when it comes to addition, but not multiplication.
c) [tex](y+9)(3/4)[/tex]
This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to [tex]\frac{3}{4}[/tex].
[tex](y+9)(3/4)\\= y(3/4)+9(3/4)[/tex]
d) [tex](9*3/4)+y[/tex]
This expression is equivalent, as 9 and [tex]\frac{3}{4}[/tex] are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:
[tex](9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}[/tex]

Kyle is at the end of a pier 30 feet above the ocean. His eye level is 3 feet above the pier. He is using binoculars to watch a whale surface. If the angle of depression of the whale is 20(degrees), how far is the whale from kyles biboculars? round to the nearest tenth foot
Answer:
96.5 feet. looked it up.
Step-by-step explanation:
Have a great day:)
Answer:
Given: the angle of depression= 20°
Height of Kyle from the ocean = 30 feet
To find: how far is the whale from kyles biboculars?
Step-by-step explanation:
Let the distance between them be y
sin20° = [tex]\frac{33 }{y}[/tex]
=> 0.342 = [tex]\frac{33}{y}[/tex] [ sin20° = 0.342]
=> y = 33/ 0.342
=> y = 96.5 ft
So, the distance between them is 96.5 ft
what is angle of depression?
The angle of depression is the angle formed by the horizontal line and the horizontal line's observation of the item. When we know the angles and the distance of an object from the ground, it is primarily utilized to find the distance between the two objects. If the line of sight is directed downward from the horizontal line, then an angle is created with the horizontal line.
The angle produced between the horizontal line and the observer's line of sight is known as the angle of depression if the object being observed is below the observer's level. The angle of depression is shown in the image below as.

Orginally each face of the pyramid shown to the. Right was a triangke withg the dimensions 109m and 190m . How far was a corner of the base from the pyramis top
Answer:
219.05 m²
Step-by-step explanation:
Dimension of right angle triangle : 109 m and 190 m
The right angle triangle has a height of 190 m and base length of 109 m
A corner of the base from the pyramid's top is equivalent to the hypotenus of the right angle triangle :
Let :
hypotenus = c ; base = b ; height = a
Hypotenus² = opposite² + adjacent²
c² = a² + b²
c² = 190² + 109²
c² = 36100 + 11881
c² = 47981
c = sqrt(47981)
c = 219.04565
A corner of the base from the pyramid's top is 219.05 m²

Six friends attend a music concert and spend $27 per ticket. They each purchase a souvenir t-shirt. If the friends spend a total of $231, how much does each souvenir t-shirt cost
Answer:
11.50
Step-by-step explanation:
6x27=162
231+-162=69
69 divided by 6 is 11.5
11.5=11.50
11.50 is your answer
Answer:
$11.50.
Step-by-step explanation:
If there are 6 friends, and every ticket costs $27, then we need to multiply.
6 x 27 = 162.
Then, we subtract the cost of the tickets so we can find the total cost of the souvenir t-shirts.
231 - 162 = 69.
Since each of the 6 friends bought a souvenir t-shirt, we divide the total cost by the number of people.
[tex]\frac{69}{6}[/tex] = 11.5.
So, each t-shirt costs $11.50.
