Answer:
V = 141.37 cm³
Surface area = 150.80 cm²
i. Doubling the radius to 6 cm, while the height remains 5
Step-by-step explanation:
Given that :
Radius, r = 3cm
Height, h = 5cm
Volume , V of right cylinder :
V = πr²h
V = π * 3² * 5
V = 141.37166
V = 141.37 cm³
Surface Area :
2πr(h + r)
2 * π * 3(3 +5)
18.849555(8)
150.79644
= 150.80 cm²
Volume at r = 6 ; h = 5
V = π * 6² * 5
V = 565.48667 cm³
Volume at r = 3 ; h = 15
V = π * 3² * 15
V = 424.11500 cm³
To increase volume,
Use synthetic division to find the result when 2x^4+11x^3+11x^2-15x-18 is divided by x-2?
at first write the first coefficient just below it then multiply with 2 ( if there is x-2 we should take 2 and vice versa ) keep repeating this process

Answer:
[tex]\displaystyle \sqrt{34}\:units ≈ 5,8\:units[/tex]
Step-by-step explanation:
No matter what happens to the shape, except for dilation, the sise will be the same, so just insert the lengths of the altitude and base into the formula, no matter if it is point D or B because of the Reflexive Property:
[tex]\displaystyle a^2 + b^2 = c^2 \\ \\ 3^2 + 5^2 = c^2 → 9 + 25 = c^2 → 34 = c^2 \\ \\ \sqrt{34} = \sqrt{c^2} \\ \\ 5,830951895 ≈ c → 5,8 ≈ c[/tex]

3. What are the intersection points of the line whose equation is y=3x +3 and the
circle whose equation is (x - 2)² + y2 = 25?
Answer:
Points of intersection of these graphs are (-2, -3) and (0.6, 4.8).
Step-by-step explanation:
Equation of the circle → (x - 2)² + y² = 25 ---------(1)
→ (x - 2)² + (y - 0)² = 5²
By comparing this equation with the standard equation of the circle,
(x - a)² + (y - b)²= r²
Here (a, b) is the center and r is the radius of the circle.
Therefore, center of the circle is (2, 0) and radius = 5 units
Second equation is a linear equation → y = 3x + 3 -------(2)
x-intercept of the equation → x = -1
y-intercept of the equation → y = 3
By graphing these equations we can get the point of intersections.
Solving these equations algebraically,
Substitute the value of y from equation (2) in the equation (1),
(x - 2)² + (3x + 3)² = 25
x² - 4x + 4 + 9x² + 18x + 9 = 25
10x² + 14x - 12 = 0
5x² + 7x - 6 = 0
x = [tex]\frac{-7\pm \sqrt{7^2-4(5)(-6)}}{2(5)}[/tex]
x = [tex]\frac{-7\pm \sqrt{169}}{10}[/tex]
x = [tex]\frac{-7\pm13}{10}[/tex]
x = -2, 0.6
From equation (2),
y = -3, 4.8
Therefore, points of intersection of these graphs are (-2, -3) and (0.6, 4.8).

The 15th term of an arithmetic sequence is 110 and the 19rd term of the sequence is 134.
a) Find the common difference.
b) Find the first term.
c) What is the 25th term?
Step-by-step explanation:
a) Common Difference = ?
15th term = 110
19th = 134
134 - 110
= 24/4
= 6
Common Difference = 6
b) First term = ?
110 = x+ (14) 6
x = 110 - 84
x = 26
First term = 26
c) 25th term = ?
= x 25 = 26+ (25)6
= x 25 = 176
25th term = 176.

A physicist needs 3,220 g of titanium to complete an experiment. She has 3 kg. How many more
kilograms of titanium does she need?
The physicist needs kg more.
(Type an integer or a decimal.)
Answer: 0.22kg
Step-by-step explanation:
if she has 3 kg then she has 3000 g. 3220-3000=220 So she needs 220 more grams of titanium. If she needs to convert how much more from grams to kilograms then 220g= 0.22kg so she needs 0.22 kg more
To check work
3kg+0.22kg= 3.22kg
3.22kg= 3,220g

Find the perimeter of the trapezoidal brick to the nearest tenth of an inch.
With a coupon, you can get a pair of shoes that normally costs $96 for $72. What percentage was the discount?
Answer:
25%
Step-by-step explanation:
96 - 72 = 24
24/96 = 0.25
0.25 = 25%
hope this helps!!
Answer:
The discount is 25%.
Step-by-step explanation:
Because you're solving for the discount, that means you have to set up the equation 72 = 96x, where x is the percent of the original price. The percent would then be 1 - x, and that would be 25% as your answer.

a. What is the circumference of the
largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for T.
b. What percent of the perimeter of the
square is the circumference of the
circle?
Answer:
Step-by-step explanation:
a. The diameter of the circle will be 30 cm
So circumference is 3.14 * 30 = 94.2 cm.
b. Required percentage = (94.2) * 100 / (4*30)
= 78.5%.

Answer:
[tex]y = x - 8[/tex]
Step-by-step explanation:
Slope-intercept form is:
[tex]y = mx + b[/tex]
Where m = slope and b = y-intercept.
It is stated that the slope of the line is 1.
It is stated that the line includes the point (0, 8)
To find the y-intercept, we can just inverse the slope-intercept form to solve for b.
[tex]b =y-mx[/tex]
We know that the point (8, 0) falls on the line, so that's what we'll use for x and y.
Then, we just have to plug those numbers in, as well as the slope.
[tex]b = 0 - (1)(8)[/tex]
Simplify.
[tex]b = 0 - 8[/tex]
Simplify again.
[tex]b = -8[/tex]
Now, we know that b = -8.
All we have left is to plug the slope and y-intercept into the slope-intercept form.
[tex]y = x - 8[/tex]
Is the product of two binomials always a trinomial? Give an example to support your answer.
Answer:
Consider: (a+b)(a-b)=a^2-ab+ab-b^2=a^2-b^2. This is a binomial. Hence, it is not always true that the product of two binomials is a trinomial.

A team can spend no more than $300 on shirts. The team has already spent $80. How many shirts for $15 each can they still buy?
Answer:
80 + 15x ≤ 300
Step-by-step explanation:
max amount = $300
already spent = $80
$300 - 80 = $220
shirts = $15 each
80 + 15x ≤ 300
$80 that is already spent + $15x ≤ $300 maximum
x = number of shirts
