Answer:
1.2 in approx
Step-by-step explanation:
Given data
Volume of the cone= 28.26 in^3
Height= 19 in
Radius= ????
We know that the volume of the cone is expressed as
V= 1/3πr^2h
substitute
28.26= 1/3*3.142*r^2*19
28.26= 19.89*r^2
divide both sides by 19.89
r^2= 28.26/19.89
r^2= 1.42
r=√ 1.42
r= 1.19
Hence the radius is 1.2 in approx

extended lm outward, what is the area of the enlarged playground ?
Answer:
464m^2
Step-by-step explanation:
Given data
Dimension of the regular playground
Length= 28m
Width= 15 m
We want to extend both sides by 1 m
Length= 28+1= 29m
Width= 15+1= 16m
Hence the area
Area=Length*Width
Area= 29*16
Area= 464m^2
The Area is 464m^2

Solve the following system of equations by substitution
2x – 3y = -1
y = x - 1
Answer:
(4, 3)
Step-by-step explanation:
Plug in x - 1 where y is. The equation will turn in 2x - 3(x - 1) = -1. Distribute, and you'll have 2x -3x + 3 = -1. Combine like terms (2x and -3x) and you'll have -x + 3 = -1. Subtract 3 from both sides, and you'll have -x = -4. Divide by -x (or -1) on both sides, and you'll have x = 4. Since y = x - 1, y = 3, since 4 - 1 = 3. Sorry if this sounds repetitive btw. Good luck :D

Which exponential function is represented by the
graph?

O f(x) = 3(3)
of(x) = 3(2)
O f(x) = 2(24)
Vo, 3)
(1.15
Answer:
C, f(x) = 3(2)^x
Step-by-step explanation:
Since the y-intercept is 3, the function will have 3 multiplying by some number to the power of x.
As x increases by 1, we notice that y multiplies by 2 every time.
This leads us to believe that the equation is 3 * 2^x
The exponential function represented by the graph is:
[tex]f(x) = 3(2)^x[/tex]
What is an exponential function?It is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value, that is, the value of y when x = 0.b is the rate of change.In the graph, there is point (0,3), hence a = 3, and it also has point (1,6), hence:
[tex]6 = 3b[/tex]
[tex]b = 2[/tex]
Thus, the equation is:
[tex]f(x) = 3(2)^x[/tex]

The measure of one interior angle of a parallelogram is 50 degrees more than 4 times the measure of another angle
The measure of the smaller interior angle is
and the measure of the larger interior angle is?
Answer:
smaller ∡ = 26°
larger ∡ = 154°
Step-by-step explanation:
opposite angles are congruent
adjacent angles are supplementary
in this problem, the angles are supplementary
'x' = measure of smaller angle
x + 50 + 4x = 180
5x = 130
x = 26
The given information and the relationship between the angles of a
parallelogram can be used to find the interior angles.
The measure of the smaller angle is 26°The measure of the larger angle is 154°Reasons:
A property of a parallelogram is that the diagonally opposite angles are
equal, and the adjacent angles are supplementary.
Therefore, two of the four interior angles of a parallelogram are equal.
Let x and y represent the two angles of different measure in the
parallelogram
y = 4·x + 50°
y + x = 180°
Which gives;
y = 180° - x
Therefore;
180° - x = 4·x + 50°
180° - 50° = 4·x + x
130° = 5·x
x = 130° ÷ 5 = 26°
x = 26°y = 4 × 26° + 50° = 154°
y = 154°Therefore;
The measure of the smaller interior angle, x = 26°The measure of the larger interior angle, y = 154°Learn more about the properties of a parallelogram here:

The equation of a circle is 3x^2+3y^2_7x_6y_3=0.Find the length of its diameter.
I assume the _ characters are supposed to be minus signs, as in
3x ² + 3y ² - 7x - 6y - 3 = 0
Move the 3 to the right sides, and complete the square in x and y :
(3x ² - 7x) + (3y ² - 6y ) = 3
3 (x ² - 7/3 x) + 3 (y ² - 2y ) = 3
x ² - 7/3 x + y ² - 2y = 1
(x ² - 7/3 x + 49/36) + (y ² - 2y + 1) = 1 + 49/36 + 1
(x - 7/6)² + (y - 1)² = 121/36
(x - 7/6)² + (y - 1)² = (11/6)²
The circle thus has radius 11/6, so its diameter is 2 • 11/6 = 11/3.
