Step-by-step explanation:
You could start by using pemdas which start with parentheses so since 3+4 is in parentheses add those first and you'll get 7 then solve the remaining 4-2 in the bracket so 4-2 is 2. Since there is no plus sign you multiply 7 by 2 then multiply by three so 7x2 is 14 then 14x3 is 42 so your answer Is 42

What is the circumference of a circle with a radius of 9.7 inches?
Use 3.14 for pi.
Enter your answer as a decimal in the box.
==================================================
Work Shown:
C = 2*pi*r
C = 2*3.14*9.7
C = 60.916
This value is approximate since pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate circumference. The circumference is the distance around the circle, aka the perimeter.
Answer:
60.916
(rounded to the two nearest decimals = 60.92, and to the first decimal = 60.9)
Step-by-step explanation:
Circumference formula: 2πr
π being pi and r being radius
Fill in your variables: 2(3.14)(9.7) or 2 x 3.14 x 9.7
use your calculator or simply solve it and you end up with 60.916.

Use the given functions represented by the equation and the graph to complete the statements.
f(x)=2x^3 - 3x^2 + 5x + 7
As x approaches positive infinity, f(x) approaches [negative infinity, positive infinity, zero] and g(x) approaches [negative infinity, positive infinity, zero]. The y-intercept of function f is [equal to, less than, greater than] the y-intercept of function g.
Answer:
f(x) approaches positive infinity.
g(x) approaches negative infinity.
the y-intercept of f(x) is less than the y-intercept of g(x).
Step-by-step explanation:
the highest power of x in f(x) is 3, and it has a positive sign. so, the bigger x the more the x³ part will dominate.
therefore, with x going to positive infinity, also f(x) goes to positive infinity.
the graph of g(x) clearly dives down never to come back up or flatten out. so, with x going to positive infinity, g(x) goes to negative infinity.
the y-intercept of f(x) = f(0).
that means the functional value when x=0.
so, for x=0 this means
y = 2×0³ - 3×0² + 5×0 + 7 = 7
the graph of g(x) shows that g(0) is 8.
so f(0) is less than g(0).
As x approaches positive infinity, f(x) approaches positive infinity and g(x) approaches negative infinity. The y-intercept of the function f is 7 and the y-intercept of function g is 8. #SPJ5

If there are 10 marbles in a bag 1/5 of them are red and the others are blue. What is the ratio of red marbles to blue marbles ?
Answer:
4:1
Step-by-step explanation:
We know 1/5 of the marbles are red.
There are 10 marbles.
1/5 is also 2/10, so:
2 of the 10 marbles are red.
To find the blue marbles, lets subtract the red marbles from the total marbles:
10-2=8
So 8 of the marbles are blue.
This is a ratio of 8 blue to 2 red marbles.
Or
4 blue to 1 red marbles.
This can be shown as:
4 : 1

if p (x) = 3x^3+2x^2+4x^4+3 and q (x) = 3x^4-2-x+5^2 .find p (x) - q (x)
Answer:
4x⁴-3x⁴+5x³-3x²+1
Step-by-step explanation:
Given that p (x) = 3x^3+2x^2+4x^4+3 and q (x) = 3x^4-2-x+5x^2
p (x) - q (x) = 3x^3+2x^2+4x^4+3 - (3x^4-2-x+5x^2)
p (x) - q (x) = 3x^3+2x^2+4x^4+3 - 3x^4 + 2 + x - 5x^2
Collect the like terms
p (x) - q (x) = 4x⁴-3x⁴+3x³+2x²-5x²+x+3-2
p (x) - q (x) = 4x⁴-3x⁴+5x³-3x²+1

Which of the two functions below has the smallest minimum y-value?
f(x) = x5 - 2
g(x) = 3x2 + 1
A. The y-values for f(x)and g(x) both go to -
B. There is not enough information to determine
C. g(x)
O D. f(x)
Answer:
They have no minimum y -value
The minimum value for y belongs to f(x) at x=0 and function f(0)=(-2), Option D is correct.
The given function f(x)= x⁵-2
Differentiating the function we get,
5x⁴=0
x=0
Therefore, f(x)=f(0)=0-2=(-2)
Now function g(x)=3x²+1
Differentiating the function we get,
6x=0
x=0
Therefore, g(x)=g(0)=0+1=1
The minimum value for y belongs to f(x) at x=0 and f(0)=(-2)

Thank you
Answer:
42
Step-by-step explanation:
From the question, we have it that 63 cups were emptied
That means the sum of both cup sizes is 63
Thus;
x + y = 63 ••••••(i)
Since each small cup is of size 8 oz and a total of x was used. The total volume from the small sized cup is 8 * x = 8x oz
similarly for the medium sized, we have 12 * y = 12y oz
The sum of both is 4(147)
8x + 12y = 4(147 )•••••(ii)
We want to get the value of x
from equation i;
y = 63-x
Substitute this into equation ii
8x + 12(63-x) = 4(147)
8x + 756 - 12x = 4(147)
12x-8x = 756-4(147)
4x = 168
x = 168/4
x = 42 small sized cups
Dominic wants to find the distance between his house on one side of the park and his school on the other side. He marks off a third point forming a right triangle, as shown in the diagram. The distances in the diagram are measured in yards. Use the Pythagorean Theorem to find the distance from Dominic’s house to the school. Sho
Answer:
The distance from the house to the school is 500 units
Step-by-step explanation:
The distance we want to calculate represents the hypotenuse of the right triangle
So, to use the Pythagoras’ theorem, we need the two other side lengths apart from the hypotenuse
The base side measures (350-50 = 300 units)
The measure of the height is (450-50 = 400 units)
Mathematically, the theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides
Thus, we have it that;
h^2 = 300^2 + 400^2
h^2 = 90,000 + 160,000
h^2 = 250,000
h = √250,000
h = 500 units

What is the radius of a hemisphere with a volume of 920 ft^3 to the nearest tenth of a foot?
Answer:
7.6 ft
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
A hemisphere is 1/2 of a sphere
V = 1/2 (4/3 pi r^3)
V = 2/3 pi r^3
920 = 2/3 pi r^3
Multiply each side by 3/2
920 * 3/2 = 3/2 * 2/3 pi r^3
1380 = pi r^3
Divide each side by pi
1380/pi = pi r^3 / pi
1380/ pi = r^3
Using pi as 3.14
1380/3.14 = r^3
439.4904459= r^3
Taking the cube root of each side
(439.4904459)^(1/3)= r^3^(1/3)
7.602967711=r
To the nearest tenth
7.6 = r
radius=7.6ft
Answer:
Solution given:
radius [r]=?
Volume of hemisphere=920ft³

Answer:
113mm^2
Step-by-step explanation:
Firstly work out the area of the pink circle using πr^2, which is the area of a process.
So we do πx12^2, which gives us 144π mm we have to divide this by two to get half of a circle hence giving us the area of the semi-circle. 72π mm is the area of the semicircle.
Then we must find the area of the white circle to subtract it from our semicircle. Since we know the radius is 12 from the center to anywhere, we know that the white circles diameter is 12, using our formula for the area all we need to do is πx6^2. This gives us 36π.
72π - 36π = 36π
36π is equal to 113.0973355 and since we need it too 3sf it will be 113mm^2

What is exponential function?An exponential function is defined by the formula f(x) = a×, where the input variable x occurs as an exponent.
Time period = x years
The number of archaeological sites discovered in a country in x years = S(x) = [tex]2(1.1)^{x}[/tex]

You want to buy the largest pizza in Northern Utah. You find a pizza that measures
75.36in around. What is the area that the pizza covers?
Answer:
451.7in^2
Step-by-step explanation:
You first need to determine the radius of the circle. This can be done by taking the circumference and dividing it by 2pi:
[tex]r=\frac{75.36in}{2\pi } = 11.99 in[/tex]
Now that you have the radius, you can plug it into the formula for the area of a circle (this is assuming the pizza is perfectly round):
[tex]A=\pi r^2=\pi (11.99^2)=451.7in^2[/tex]
The area that covers the circular pizza is: 451.64 in.²
What is the Area and Perimter of a Circle?Area = πr²
Perimeter = 2πr, where r is the radius of the circle.
Given the following:
Perimeter of the circular pizza = 75.36 in.
Find the radius:
2πr = 75.36
r = 75.36/2π
r = 11.99 in.
Find the area:
Area = π(11.99)²
Area = 451.64 in.²
