Answer:
a) There is an integer a such that [tex]\frac{a-1}{a}[/tex] is an integer
b) False
Step-by-step explanation:
Statement : ∀a ∈ Z, (a − 1) a is not an integer
A) The correct negation will be :
There is an integer a such that [tex]\frac{a-1}{a}[/tex] is an integer
B) The Given statement is FALSE because
when we assume the value of a = 1
( a - 1 ) / a = (1 - 1 ) / 1 = 0 ; which is an integer
Pls answer I got 15 points and omg pls be correct
Answer:
$119.79
Step-by-step explanation:
Formula:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Given:
P = 90
r = 0.1
t = 3
n = 1
Work:
[tex]A=P(1+\frac{r}{n} )^{nt}\\\\A=90(1+\frac{0.1}{1} })^{3*1}\\\\A=90(1.1)^3\\A=90(1.331)\\A=119.79[/tex]

Select the function that is nonlinear.
a
y = 3x - 4
b
y = 2x3 - 10
c
y = 4x -12
d
y = x + 101
Answer:
B
Step-by-step explanation:
A C and D are all linear. The powers on x in all three questions is 1. For example the first answer could be written as y = 3x^1 - 4. C and D are much the same.
So if you are thinking that B must be the answer, you would be right. x is raised to the third power -- or I think that is what is intended. y = x^3 - 10
Which of the following could be the ratio between the lengths of the two legs
of a 30-60-90 triangle?
Check all that apply.
O A. 1: 13
O B. 3: 315
O C. :
OD. 1: 12
O E. : 13
O F. 13:3
Answer:
Step-by-step explanation:
we know that
In a triangle
the ratio between the lengths of the two legs is equal to the tangent
so
therefore
the answer is
Option B
-------> could be the ratio
because is the value of the
Option C
------> could be the ratio
because is the value of the
Option E
-------> could be the ratio
because is the value of the
The options B, C and E giving the ratios are correct.
What are ratios?Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Given that, a 30-60-90 right triangle, we need to find the ratio between the lengths of the two legs of the triangle,
Since, we know that,
In a right triangle, the ratio between the lengths of the two legs is equal to the tangent.
so,
Tan 30° = 1/√3
Also,
√3 / 3 = 1/√3
3/3√3 = 1/√3
Hence, the options B, C and E giving the ratios are correct.

What is the approximate surface area of the Hayden Sphere in terms of T?
4731 ft?
37857 ft?
75697 ft2
18927 ft?
Answer:
[tex]A=7569\pi \ ft^2[/tex]
Step-by-step explanation:
The diameter of a sphere is 87 feet.
We need to find its surface area. The formula for surface area is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the sphere
[tex]A=4\pi \times (\dfrac{87}{2})^2\\\\=7569\pi \ ft^2[/tex]
So, the surface area of the sphere is equal to [tex]7569\pi \ ft^2[/tex].

Answer:
No
Step-by-step explanation:
A function gives only one output per input, which means an x value can only give one y value. Assuming the right side is f(x) and the left is x:

The giant outlier is Palm Beach county. We can see that it lies well beyond the range of votes this regression model would predict for Buchanan, based on the observed linear trend between total votes and votes for Buchanan across all the other counties. Calculate the residual for Palm Beach county to determine just how much larger Buchanan's vote total was compared to what we'd predict based on the election results from the other counties.
Answer:
Hello your has some missing information attached below is the missing information
answer : 2355.62
Step-by-step explanation:
Calculating the residual for Palm Beach county
Given that total votes = 430772
and The regression equation = 56.115131 + 0.0023197 * Total Votes
The predicted Buchanan = 56.115131 + 0.0023197 * 430772 = 1055.377
while the Actual Votes Buchannan = 3411
Residual for Palm Beach county = Actual votes Buchannan - Predicted
= 3411 - 1055.377 = 2355.62

Find the dot product of vectors u = -4i + 7j and v = 2i + j
Answer:
The desired dot product is -1
Step-by-step explanation:
To find the dot product of the given vectors, multiply the magnitudes of the 'i' and 'j' terms together, separately, and then add the results:
dot product of u and v = (-4)(2) + (7)(1) = -8 + 7 = -1
The desired dot product is -1

Jeremy has a stand in the farmer's market where he sells strawberries by the pound. The table shows the weights of the strawberries and the prices per quantity. The relationship between the amount of strawberries in pounds and the price is a proportional relationship.
Which statement is true?
A.)The table does not represent a proportional relationship because the differences between consecutive terms in each column do not have the same ratio.
B.)The table does not represent a proportional relationship because the ratio between the price column and the weight column is not the same for each row.
C.)The table represents a proportional relationship because the differences between consecutive terms in each column have the same ratio.
D.)The table represents a proportional relationship because the ratio between the price column and the weight column is the same for each row.

If y=4, what does x equal??
Answer:
since y=4
from one of the equations
6x+4y=46
substitute y=4 In the equation
6x+4(4)=46
6x+16=46
6x=46-16
6x=30
divide both sides by the co efficient of'x'
6x/6=30/6

12/23 plus -11/23 e eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Answer:
1/23
Step-by-step explanation:
This honestly super easy, but here it is!
12/23+(-11/23)
With no negatives, it would be 12/23+11/23 and the answer would be 23/23 AKA 1, because 12+11=23.
With negatives though, you always have to subtract the number itself from the positive number if the number is negative. Here we will subtract 11 from 12, which brings us to 1/23.
Hope this helped!

Answer:
7. 4 cm
8. 206 paper cups
9. 175pi cm³
Step-by-step explanation:
7. The formula for the volume of a cone can be used.
V = 1/3πr²h
h = 3V/(πr²) = 3(48π cm³)/(π(6 cm)²) = 144/36 cm = 4 cm
The height of the cone is 4 cm.
__
8. The volume of the cone with the given dimensions is ...
V = 1/3π(4 cm)²(11 cm) = 176/3π cm³ ≈ 184.307 cm³
The number of times this volume can be filled by 10 gallons is ...
(10 gal)(3785 cm³/gal)/(184.307 cm³/cup) = 205.3 cups
206 paper cups are needed.
__
9. We know from the formula for the volume of a cone that it has the same volume as a cylinder 1/3 its height. The composite figure is equivalent to a cylinder with a height of ...
3 cm +(12 cm)/3 = 7 cm
Then the volume is ...
V = πr²h
V = π(5 cm)²(7 cm) = 175π cm³
__
For this, we recognize that the triangle with sides h, 5, and 13 will be a 5-12-13 right triangle, so the height of the conical part of the figure is h=12 cm. If you haven't remembered that Pythagorean triple, you can find the height from the Pythagorean theorem:
h² +5² = 13²
h = √(169 -25) = √144 = 12
