The height of Joseph in meters is 1.79 m.
What is Height?
Height, altitude, elevation mean vertical distance either between the top and bottom of something or between a base and something above it. Height refers to something measured vertically whether high or low.
Here, Height of Joseph = 5.9 ft.
1 feet = 0.304 m
5.9 ft = 0.304 X 5.9 m.
5.9 ft = 1.79 m.
Thus, the height of Joseph in meters is 1.79 m.

A scale drawing of a square object has a scale of 1 in. : 5 mm. The scale drawing has a length of 2.5 inches. Find the perimeter and the area of the object in the scale drawing. Then find the perimeter and area of the actual object.
Answer:
Perimeter and area of drawing
Perimeter= 10 In
Area = 6.25 In²
Perimeter and area of object
Perimeter = 51.836 mm
Area = 167.936 mm²
Step-by-step explanation:
We are dealing with a square object, so let's talk about the drawing first.
The length of one side = 2.5 In
Perimeter of square= 4L
Perimeter = 4*2.5
Perimeter= 10 In
Area = L*L
Area = 2.5*2.5
Area = 6.25 In²
Letd note that 1 inch =
25.4 millimetres
So 2.5 Inch = 2.5 * 25.4
2.5 In = 63.5 mm.
25.4 mm is to 5mm
63.5 mm is to (63.5*5)/24.5
63.5mm is to 12.959 mm
So the length of actual object is 12.959mm
The perimeter = 4*12.959
Perimeter = 51.836 mm
Area = 12.959²
Area = 167.936 mm²
Answer:
The perimeter of the actual object is 50 mm.
The area of the actual object is 156.25 mm square
Step-by-step explanation:
Given
Shape: Square
Scale: 1 in : 5 mm
Length of Scale Drawing = 2.5 in
Required:
- Perimeter of Actual Object
- Area of Actual Object
Calculating the perimeter of the actual object
Provided that the shape is a square;
The perimeter of the actual object is calculated by
Perimeter = 4 * Length
Recall that the scale is 1 in : 5 mm
This means 1 in on the scale represents 5 mm of the actual measurements of the object.
So, if 1 in ≈ 5 mm, then
2.5 in ≈ 2.5 * 5 mm
2.5 in = 12.5 mm
So, Length = 12.5mm
Now, the perimeter of the actual object can be calculated.
P = 4 * 12.5mm
P = 50mm
Hence, the perimeter of the actual measurements is 50 mm.
Calculating the area of the actual object
The area of the actual object is calculated by
Area = Length * Length
Recall that Length = 12.5 mm as calculated above
So,
Area = 12.5 * 12.5
Area = 156.25 mm square
Hence, the area of the actual object is 156.25 mm square

If sin = O =5/6, what are the values of cos O and tan O? (2 points)
Answer:
[tex]cos(\alpha )=\frac{\sqrt{11} }{6}[/tex] and [tex]tan(\alpha )=\frac{5\sqrt{11} }{11}[/tex]
Step-by-step explanation:
First we would need to solve for the missing leg in order to figure out the remaining answers.
To do this we can use the Pythagorean Theorem a² + b² = c²
Our missing leg in this case is a, so solving for a gives us [tex]a=\sqrt{c^{2} -b^{2} }[/tex]
Here our b is 5 and our c is 6. So plugging in these values we get [tex]a=\sqrt{(6)^{2}-(5)^{2} } =\sqrt{36-25} =\sqrt{11}[/tex]
With this missing leg being solved, we can use trig identities to solve for cos and tan
I used the trig identity [tex]sin(\alpha )=\frac{opposite}{hypotenuse}[/tex] to set up the triangle in the attached image. We can use the trig identity [tex]cos(\alpha)=\frac{adjacent}{hypotenuse}[/tex] which would give us [tex]cos(\alpha )=\frac{\sqrt{11} }{6}[/tex] and we can use the trig identity [tex]tan(\alpha ) = \frac{opposite}{adjacent}[/tex] which would give us [tex]tan(\alpha )=\frac{5}{\sqrt{11} } =\frac{5\sqrt{11} }{11}[/tex]
Answer:
As trigonometry property:
(sinO)^2 + (cosO)^2 = 1
tanO = sinO/cosO
Then, if sinO = 5/6 = 0.83
=> (5/6)^2 + (cosO)^2 = 1
=> cosO = +/- sqrt(1 - (5/6)^2) = +/- 0.55
=>tanO = +/- 0.83/0.55 = +/- 1.51
Hope this helps!

A circle has the equation x2+y2+16y−30x=0.
What is the equation of the circle in standard form, the coordinates of its center, and the length of its radius?
The equation of the circle is (x+15)2+(y−8)2=289; the center is at (−15,8), and the radius is 17 units.
The equation of the circle is (x−15)2+(y+8)2=289; the center is at (−15,8), and the radius is 289 units.
The equation of the circle is (x−15)2+(y+8)2=289; the center is at (15,−8), and the radius is 17 units.
The equation of the circle is (x−15)2+(y+8)2=289; the center is at (15,−8), and the radius is 289 units.
Answer:
Step-by-step explanation:
hello :
x2+y2+16y−30x=0 means : (x²-30x)+(y²+16y) =0
(x²-30x+15²)-15²+(y²+16y+8²) -8²=0
(x-15)²-225+(y+8)²-64=0
(x-15)²+(y+8)²=289=17²......standard form when the center is (15,- 8)
and radius 17
Final answer:
To transform x^2+y^2+16y-30x=0 into the standard form of a circle equation, we must complete the square to obtain (x-15)^2+(y+8)^2=289. The circle's center is at (15, -8) and has a radius of 17 units.
Explanation:
To rewrite the given equation of the circle x^2+y^2+16y−30x=0 into standard form, we must complete the square for both x and y terms. First, rearrange the equation to group x and y terms together: x^2−30x + y^2+16y = 0. To complete the square, take half of the coefficient of x, which is −15, square it to get 225, and add it to both sides. Similarly, take half of the coefficient of y, which is 8, square it to get 64, and add it to both sides as well.
After adding these values, the equation becomes x^2−30x+225 + y^2+16y+64 = 225+64. Now it can be written as (x−15)^2 + (y+8)^2 = 289.
The standard form of a circle's equation is (x - h)^2 + (y - k)^2 = r^2, where (h,k) is the center of the circle and r is the radius. Thus, from our equation (x−15)^2 + (y+8)^2 = 289, the center is at (15, −8) and the radius is √289 which is 17 units.
Therefore, the correct statement is: 'The equation of the circle is (x−15)^2+ (y+8)^2=289; the center is at (15, −8), and the radius is 17 units.'
A circle has the equation (x−13)2+(y−1)2=4.
A: What is the center of the circle?
B: What is the radius of the circle?
Select two answers: one for question A, and one for question B.
A: (13,1)
B: 4
A: (−13,−1)
A: (−13,1)
A: (13,−1)
B: 2
B: 2–√
Final answer:
The center of the given circle is at (13, 1), and the radius of the circle is 2.
Explanation:
The equation of a circle is generally given in the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius. Looking at the given equation (x - 13)^2 + (y - 1)^2 = 4, we can see that it is already in this standard form.
To answer the questions:
The center of the circle is (13, 1), which comes from the terms within the parentheses being subtracted from x and y.
The radius of the circle is not simply 4, as one might surmise by a quick glance. Instead, the equation gives us the radius squared, r^2 = 4. Taking the square root of both sides, we find that the radius, r, is 2.

Suppose a parabola has vertex (-8, -7) and also passes through the point (-7,-4). Write the equation of the parabola invertex form
Answer:
y = 3 (x+8)^2 -7
Step-by-step explanation:
The vertex form of the equation is
y = a(x-h)^2 +k
where (h,k) is the vertex
y = a (x- -8)^2 + -7
y = a (x+8)^2 -7
Now substitute the point into the equation to determine a
-4 = a (-7+8)^2 -7
-4 = a (1^2) -7
-4 = a -7
Add 7 to each side
-4+7 = a-7+7
3 =a
y = 3 (x+8)^2 -7
Answer:
y = 3(x + 8)² - 7
Step-by-step explanation:
y = a(x - -8)² - 7
