Answer:
a = 32,37
b=99
Step-by-step explanation:
a = 32,369
The third decimal place is greater (or equal) than 5, so we need to add one unit to the second place.
= 32,37
b = 99,004
The third decimal place is lesser than 5, so we can simply delete it.
= 99,00
Since only zero in every decimal places are not relevant, we can remove them:
= 99

The graph of g(x) below resembles the graph of f(x)=x^2, but it has been changed. Which I'd these is the equation of g(x)?
Answer:
[tex]A) \displaystyle g(x) = 4 {x}^{2} + 2[/tex]
Step-by-step explanation:
recall that,
[tex] \displaystyle \rm Q _{ \text{standard}} :g(x) = {ax}^{2} + bx + c[/tex]
remember that,
Larger values of 'a' squash the curve inwardsSmaller values of 'a' expand it outwardsAnd negative values of 'a' flip it upside downsince the Parabola squashes inwards we assume a=4
we know that,
when c is positive the Parabola goes upwardswhen c is negative the parabola goes downwardsas the Parabola goes upwards by 2 units we assume c is 2
hence,
our best answer choice is a
If the cost to fill the pool is $2.55 per cubic foot, how much will it cost to fill the pool?
It will cost $
to fill the pool.
Answer:
$1346.40
Step-by-step explanation:
Find the volume of the pool first:
volume = cubiod + triangular prism
volume = (8*6*8) + (8*6*6)/2
volume = 528 cubic feet
price = price per cubic foot * cubic feet
price = $2.55 * 528 cubic feet
price = $1346.40

Answer:
C. y = 8x
Step-by-step explanation:
Using the slope formula, we can calculate the rate of Marisol's and Timothy's Machines.
[tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex]
Marisol:
[tex]m = \frac{18-12}{3-2} \\m=6[/tex]
Timothy:
[tex]m=\frac{54-36}{6-4} \\m=\frac{18}{2} \\m=9[/tex]
Now that we know the rate of their machines, we need to choose a rate that is between 6 and 9. Therefore, the rate of Zorian's machine needs to be y = 8x.

What is Pythagoras' Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).
We are given the measure of sides;
NP²= 10²+7²+5²
NP²=100+49+25

Answer:
Absolute error = 0.6m
Percentage error = 6%
Step-by-step explanation:
Given that :
Actual height = 10.4 m
Estimated height = 11 m
Tbe percentage error :
The absolute error :
|Actual value - Estimated value|
|10.4 - 11| = 0.6 m
Percentage error :
|Actual value - Estimated value| / actual value * 100%
(0.6 / 10) * 100%
0.06 * 100%
= 6%
To which rational number to which rational subset(s) does the following number belong?
15
1. Rational Numbers
II. Natural Numbers
III. Whole Numbers
IV. Integers
Answer:
15 belongs to the set of natural numbers , whole numbers , integers & rational numbers.
Step-by-step explanation:
TO FIND :-
those subsets to which 15 belongsFACTS TO KNOW BEFORE SOLVING :-
N = Set of all natural numbers
W = Set of all whole numbers
Z = Set of all integers
Q = Set of all rational numbers
It can be said that :-
N ⊂ W (∵ Whole numbers include all natural numbers along with 0)W ⊂ Z (∵ Integers include positive numbers i.e. whole numbers along with negative numbers.)Z ⊂ Q (∵ Rational numbers include all integers along with fractions.)Hence , N ⊂ W ⊂ Z ⊂ Q
SOLUTION :-
Method 1 -
{15} ⊂ N (∵ 15 is an element of set N. {15} a singleton set & it can be called as the subset of N )
⇒ {15} ⊂ N ⊂ W ⊂ Z ⊂ Q
∴ 15 belongs to the set of natural numbers , whole numbers , integers & rational numbers too.
Method 2 -
A rational number is a number which can be expressed in "p/q" form where p,q are integers & q ≠ 0. 15 can also be expressed as [tex]\frac{15}{1}[/tex]. Hence, 15 is a rational number i.e. it belongs to the set of rational numbers.Natural numbers are the countable numbers. 15 is a countable number. So , 15 is a natural number i.e. 15 belongs to the set of natural numbersWhole numbers include all natural numbers as well as zero. 15 is a natural number. So , 15 is also a whole number i.e. 15 belongs to the set of whole numbers.Integers include the negative numbers as well as whole numbers. 15 is a whole number. So , 15 is also an integer i.e. 15 belongs to the set of all integers.answer quick!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Solve the following system of equations.
y=2x+16
2x−7y=−64
Possible answers
-4,8 -1,11 -7,11
Answer:
x = -4, y = 8
Step-by-step explanation:
y = 2x + 16 -----(1)
2x - 7y = - 64 -------(2)
Substitute (1) in (2)
2x - 7(2x + 16) = - 64
2x - 14x - 112 = - 64
-12x = -64 + 112
-12x = 48
x = -4
Substitute x = -4 in (1)
y = 2(-4) + 16
y = -8 + 16
y =8
Answer:
It is -4,8.
Step-by-step explanation:
y=2x +16
{
-7y=-2x-64
-6y=-48
y=8 then using substitution you will get x=-4

09.03 MC) What is the domain of the following parabola? (5 points) u-shaped graph that opens down with a vertex of 2, 3 Select one: a. x ≥ 2 b. x ≤ −1 c. y ≤ 3 d. All real numbers
Answer:
The correct option is d: All real numbers.
Step-by-step explanation:
For a function f(x), the domain is the set of all the possible values of x that we can input in that function.
A general way to find the domain of a function is:
First, assume that the domain is the set of all real numbers.
Then, look at restrictions implied:
like in functions like:
f(x) = 4 if x > 3
Here the domain of the function is implied.
Third, let's find values of x that make "problems" with our function (for example, a zero in the denominator) and then remove these points from the domain.
In this case, we have a quadratic function:
y = a*x^2 + b*x + c
Here we do not have any problem (like a zero in a denominator), and we do not have any restrictions (We only know that the parabola is U shaped, so it is a function, and that its vertex is (2, 3) )
Then we can conclude that the domain of this function is the set of all real numbers.
The correct option is d: All real numbers.

Number 1 is wrong correct answer: 5/12
Solve the following using substitution method
Solution :
2a + 2b = 7 ...1)
4a + 3b = 12 ...2)
In equation, 1)
a = (7 - 2b)/2 ...3)
Putting value of a in equation 2) we get :
4 × (7 - 2b)/2 + 3b = 12
2( 7 - 2b ) + 3b = 12
14 - 4b + 3b = 12
b = 2
Putting value of b in 3) we get :
a = ( 7 - 2×2)/2
a = 3/2 = 1.5
Now,
2x - 3y = 16 ...5)
x + 2y = -6 ...6)
x = -6 - 2y
Putting above value of x in eq 5) , we get :
2( -6 - 2y ) - 3y = 16
-12 - 4y - 3y = 16
7y = -28
y = -4
x = -6 - ( 2× -4 )
x = 2
Hence, this is the required solution.

Answer:
1300 cm = 13 m
Step-by-step explanation:
We need to find meters in 1300 cm.
We know that,
1 m = 100 cm
1 cm = (1/100) m
It means,
[tex]1300\ cm=\dfrac{1300}{100}\ m\\\\=13\ m[/tex]

Answer:
24
Step-by-step explanation:
Let's do the smaller parts at the edge.
The formula for a triangle is 1/2bh
The base is 3 the height is 4
3 times 4 is 12
12 divided by 2 is 6
Since there are two of the same triangle on the edge both of the triangle's area is 6 which is 12
No for the upper triangle, the base is 6 and the height is 4
4 times 6 is 24
24 divided by 2 is 12
12 plus 12 is 24
The answer is
The area of the shaded parts of the triangle is 24 in^2

through the point (6, 8)?
O A. y= -1/3x+10
O B. y= -1/3x + 4
O C. y= 1/3x+6
O D. y= -1/3x+8
Answer:
A. y=-1/3x+10
Step-by-step explanation:
Perpendicular gradients(slopes) are negative reciprocals so
m=-1/3 then use the point (6,8) to find the equation of the line
y=mx+b
8=(-1/3)(6)+b
8=-2+b
b=10
y=-1/3x+10
