The diameter of a human hair is about 0.00067 inches in length. How is this length
expressed in sclentific notation?
A 6.7 x 10 4in.
B 67 x 10 4 In.
C 6.7 x 10-4 in.
D 67 x 10-4 in.
Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.

Step-by-step explanation:
1). What are the vertices of the hyperbola whose equation is:
( y + 6 ) ² ( x + 8 ) ²
_____ - _____
81 49
2). What are the foci of the hyperbola whose equation is:
( x - 6 ) ² ( y + 7 ) ²
_____ - _____
16 9
Answer:
1) The vertices of the hyperbola are (-8, -15), (-8, 3)
2) The foci of the hyperbola are (11, -7) or (1, -7)
Step-by-step explanation:
1) The vertices of a hyperbola given in the form [tex]\dfrac{\left (y - k\right)^2}{a^2} -\dfrac{\left (x - h\right)^2}{b^2} = 1[/tex] is (h, k ± a)
Therefore, for the given hyperbola with the following equation;
[tex]\dfrac{\left (y + 6\right)^2}{81} -\dfrac{\left (x + 8\right)^2}{49} = 1[/tex], we have;
[tex]\dfrac{\left (y + 6\right)^2}{9^2} -\dfrac{\left (x + 8\right)^2}{7^2} = 1[/tex]
Therefore the vertices are;
(-8, -6 ± 9) = (-8, -15), (-8, 3)
2) The equation of the given hyperbola is presented as follows;
[tex]\dfrac{\left (x - 6\right)^2}{16} -\dfrac{\left (y + 7\right)^2}{9} = 1[/tex]
The given hyperbola is of the form;
[tex]\dfrac{\left (x - h\right)^2}{a^2} -\dfrac{\left (y - k\right)^2}{b^2} = 1[/tex]
We get;
[tex]\dfrac{\left (x - 6\right)^2}{4^2} -\dfrac{\left (y + 7\right)^2}{3^2} = 1[/tex]
The foci is then (h ± c, k)
Therefore, by comparison, the foci of the given hyperbola is (6 ± c, -7)
Where c² = a² + b²
∴ c² = 4² + 3² = 25
c = √25 = 5
∴ The foci; (6 ± 5, -7) = (11, -7) or (1, -7).

11 5(2x + 1) + c(x + d) = 12x - 1
Work out the value of c and the value of d.
Answer:
c = 2, d = - 3
Step-by-step explanation:
Expand and simplify the left side then compare the coefficients of like terms on both sides.
5(2x + 1) + c(x + d) ← distribute parenthesis
10x + 5 + cx + cd
= x(10 + c) + 5 + cd
Compare like terms on both sides, that is
10 + c = 12 ( subtract 10 from both sides )
c = 2
Then
5 + cd = 5 + 2d and
5 + 2d = - 1 ( subtract 5 from both sides )
2d = - 6 ( divide both sides by 2 )
d = - 3

The radius of a baseball is approximately 2.5 inches. What is its volume?
Answer:Below
Step-by-step explanation:
A baseball is round.
So, the diameter and the height are the same.
The radius is half of the diameter, so: 2.5 x 2 = 5
The height is also 5.
The Volume is 65.45
Answer:
Step-by-step explanation:
The Volume is 65.45

Help me with this for brainiest
Answer:
11) 2 x 3.14 x (19/2) > (we want to use the radius)
2 x 3.14 x 9.5 = 59.66
12) 2 x 3.14 x (11/2) > (we want to use the radius)
2 x 3.14 x 5.5 = 34.54
34.54/2 + 11 = 28.27 >(becuase it is only a semicircle)
the plus 11 is the diameter, because the cirlce is cut in half

The equation of a circle centered at the orgin is x^2 + y^2 = 16. What is the radius of the circle
Given:
The equation of the circle is:
[tex]x^2+y^2=16[/tex]
To find:
The radius of the circle.
Solution:
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is the center and r is the radius.
We have,
[tex]x^2+y^2=16[/tex]
In can be written as:
[tex]x^2+y^2=4^2[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]h=0[/tex]
[tex]k=0[/tex]
[tex]r=4[/tex]
Here, the center of the circle is the origin and the radius is equal to 4 units.
Therefore, the radius of the given circle is 4 units.

A computer originally priced at $850 is on sale for 15% off. What is the sale price of the computer?
Answer:
Sale price: $722.50
Step-by-step explanation:
Subtract 15% from 100%, obtaining 85%. The computer is sold for 85% off.
Converting this 85% to a mixed decimal, we get 0.85, and then we multiply the original price ($850) by this 0.85: 0.85($850) = $722.50
The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.

Each color is a
different digit
eren
Answer:
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
Step-by-step explanation:
P.S - The exact question -
Given - The diagram
To find - The number that represent Red, Silver and Blue color.
Proof -
Let the number printed in red color = r
Let the number printed in silver color = s
Let the number printed in blue color = b
Also,
Given that the equation is -
b s r
b s r
+ b s r
= r r r
Now,
We have to think of a number that if we add the last digit of the number gives the same last digit.
Bt inspection ,
the number would be 5
Because 5 + 5 + 5 = 15
Lat place of the equation is same
So,
The number printed on red color = 5
⇒r = 5
So, the equation becomes
b s 5
b s 5
+ b s 5
= 5 5 5
Now,
We have to think of a number whose last digit add up to 3 + 1 gives the last digit number 5 ( we add 1 because by adding 5 + 5 + 5 , we get 15 so we write the last digit 5 and 1 goes to the remainder and that remainder 1 will add up in the next number addition)(addition rule)
i.e.
s + s + s + 1 = number whose end digit is 5
By inspection,
The number would be 8
because 8 + 8 + 8 + 1 = 25
So,
we get
s = 8
So, the equation becomes
b 8 5
b 8 5
+ b 8 5
= 5 5 5
Now,
By same process , we will find the number of blue color
By inspection the number on blue color = 1
∴ we get
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
and the equation is -
1 8 5
1 8 5
+ 1 8 5
= 5 5 5

[tex] \boxed{(6, -3)} [/tex]
Step-by-step explanation:
Given the ratio 5:3
and Points A and B where A is located at (-6, 3), and B is located at (26, -13).
Let point A be [tex] (x_{1}, y_{1}) [/tex], and let point B be [tex] (x_{2}, y_{2}) [/tex].
(-6, 3) → [tex] (x_{1}, y_{1}) [/tex].

To solve, just substitute these variables into the expressions of these coordinates to get the answer.
[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex] →
[tex] (\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)}) [/tex] →
[tex] (\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)}) [/tex] →
[tex] (\frac{-30 + 78}{8}, \frac{15+ -39}{8}) [/tex] →
[tex] (\frac{78 – 30}{8}, \frac{15 – 39}{8}) [/tex] →

cosx (2 sinx+1)=0
Answer:
x = pi/2 and 11pi/6
Step-by-step explanation:
Given the trigonometry expression
cosx (2 sinx+1)=0
This can be written in two forms as;
cosx = 0 and 2sinx + 1 = 0
If cos x = 0
x = arccos0
x = 90degrees
x = pi/2
Similarly
2sinx + 1 = 0
2sinx = -1
sinx = -1/2
sinx =-0.5
x = aarcsin(-0.5)
x = -30
Since sin is negative in the third and 4th quadrant
x = 270 + 30
x = 330degrees
x = 330pi/180
x = 11pi/6

Answer:
17.6 squared feet
Step-by-step explanation:
triangle is 0.5 X b X h
0.5 X 1 X 2 = 1 squared foot.
(there are two triangles) 1 X 2 = 2 squared foot
rectangle sides
2.2 X 3 = 6.6
1 X 3 = 3
2 X 3 = 6
add them altogether
2 + 6.6 + 3 + 6 = 17.6

Find the value of sin^-1(4pi/5)
Answer:
No value because 4π/5 exceeds the domain
Step-by-step explanation:
The domain and range of sin^-1(x) is a domain of [-1,1] and a range of [-π/2,π/2]
Since 4π/5>1, this exceeds the domain and therefore has no value.
