Answer:
Well, 1 is 3.8 The second one is 40,
Step-by-step explanation:
I believe 1 is 3.8, b/c 1.9*2 is 3.8, and the difference between exponents makes 3 zeros, so 2000.
The second one is 40, I confirmed this by doing .0001 to replicate 10 to the negative 4th power
By doing 9.5*.0001*40, I got the 0.038 from 1
Answer:
3.8 × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also 4 times greater than 9.5 x 10-4.
Step-by-step explanation:
I started by doing 0.0000019 x 2000 and got 0.0038. If you move the decimal point 4 over you get 3.8.
EVERYONE ELSE IS WRONG!!! I got this correct on the test after retaking it, the second one is NOT 40 it is 4.
Identify the function shown in this graph.
O A. y=-3x+1
B. y = 3x + 1
C. y = 12+1
D. y = 3x - 1
Answer:
y = 3x + 1
Step-by-step explanation:
As you can see the y-intercept is at the number 1
and for the slope, if u do rise over run or y/x you get....
3/1 = 3
So the slope is 3

Graph g is a translation of the graph of y= sin x (dashed line).a) write down the equation of g b) write down the coordinates of the point p
Answer:
a) [tex]G(x)= \sin x + 2[/tex]
b) The coordinates of P are
[tex]\displaystyle \left( \frac{3\pi}{2},1\right)[/tex]
Step-by-step explanation:
Translation
The dashed line shows the graph of the function
[tex]y = \sin x[/tex]
This function has a maximum value of 1, a minimum value of -1, and a center value of 0.
a)
Graph G shows the same function but translated by 2 units up, thus the equation of G is:
[tex]\boxed{G(x)= \sin x + 2}[/tex]
b) The coordinates of P correspond to the value of
[tex]x = \frac{3\pi}{2}[/tex]
The value of G is
[tex]\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2[/tex]
Since
[tex]\sin \frac{3\pi}{2}=-1[/tex]
[tex]\displaystyle G(\frac{3\pi}{2})= -1+ 2=1[/tex]
The coordinates of P are
[tex]\displaystyle \left( \frac{3\pi}{2},1\right)[/tex]

Sandra is now three times as old as her daughter .Five years ago her age was 10 years more
Step-by-step explanation:
This is an incomplete question. Kindly complete it for assistance
Step-by-step explanation:
Aaron (A)=30 years old currently. (Aaron's son (S)=10 years old currently)
PREMISES
3S+10=2(S+10)
ASSUMPTIONS
Let A=Aaron's “current” age (3S in terms of his son's age)
Let S=Aaron's son's “current” age (S)
CALCULATIONS
3S+10=2(S+10)
3S+10=2S+20
(3S-2S)+10=(2S-2S)+20
S+10=0+20
S+(10–10)=20–10
S+0=10
S=
10 years old
and,
if S=10 years old, then
A=3S (Aaron's “current” age in terms of his son's age)
A=3(10)
A=
30 years old
PROOF
If A=30 years old, then the equations
3S+10=2(S+10)
3(10)+10=2(10)+20
30+10=20+20 and
40=40 establish the roots (zeros) A, S={30 years old, 10 years old} of the mathematical statement 3S+10=2(S+10)

how do you find the value in a ratio?
Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6∶8 and the ratio of oranges to the total amount of fruit is 8∶14.

Step-by-step explanation:
The increase in pressure (P) is a linear function of the depth (d) to which a scuba diver descends. This is the function: P(d)=0.445d + 14.7.
1.) What does the initial value represent?
2.) What does the rate of change represent?
Answer:
Initial value = 14.7
Rate of change = 0.445
Step-by-step explanation:
Given the linear function :
P(d) = 0.445d + 14.7
The linear equation above takes the general. Form of a slope - intercept equation :
y = mx + c
Where ; m = slope or gradient = rate of change in y per unit change in x
c = intercept , which is the intial value of y when x = 0
Thus using the above information ;
Initial value = intercept value = 14.7
The rate of change is the slope value = 0.445
The terminal side of ø quadrant IV and sin ø = -12/13. What is the cos ø?
A. 5/13
B. 5/12
C. -5/12
D. -5/13
Answer:
Step-by-step explanation:
cos^2θ = 1 - sin^2θ = 1 - 144/169 = 25/169
cos θ is positive in Quadrant IV
cos θ = √(25/169) = 5/13
The value of the cos θ is 5/13 because cos is positive in IV option (A) is correct.
What is Trigonometric functions?Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.
We have: The terminal side of θ is in quadrant IV quadrant
sinθ = -12/13
cos²θ = 1 - sin²θ
cos²θ = 1 - (-12/13)²
cos²θ = 1 - 144/169
cos²θ = 25/169
cos θ = √(25/169)
cos θ = 5/13
cos θ is positive in Quadrant IV
Thus, the value of the cos θ is 5/13 because cos is positive in IV option (A) is correct.

The number of times that interest is compounded per year is represented by the variable ____.While the annual interest rate is represented by___.
Answer:
1. (n) 2. (r)
Step-by-step explanation
interest compounded per year is (n),
annual interest rate is (r).
The number of times that interest is compounded per year is represented by the variable n. While the annual interest rate is represented by r.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].
A = amount, P = principal, r = rate of interest, n = number of times interest is compounded per year and t = time (in years).
Therefore, the number of times that interest is compounded per year is represented by the variable n. While the annual interest rate is represented by r.

A point K is on the perpendicular bisector of a segment with endpoints at H and J. What must be true about point K? It is equidistant from H and J It falls on the h j It is at the midpoint of h j Not enough information is given
Answer:
[tex]K[/tex] is equidistant from [tex]H[/tex] and [tex]J[/tex].
Step-by-step explanation:
Given that the point [tex]K[/tex] which is on the perpendicular bisector of the line segment having endpoints at [tex]H[/tex] and [tex]J[/tex].
The given situation can be represented as the diagram as attached in the answer area.
Referring to the [tex]\triangle HOK, \triangle JOK[/tex]:
[tex]\angle HOK = \angle JOK=90^\circ[/tex] (As it is the perpendicular bisector)
[tex]OH = OJ[/tex] (As it is the perpendicular bisector)
Also, the side [tex]OK[/tex] is the common side.
Therefore by [tex]S-A-S[/tex] congruence, [tex]\triangle HKO\cong \triangle JKO[/tex]
As per the properties of congruent triangles:
Side [tex]HK[/tex] = Side [tex]JK[/tex]
[tex]HK[/tex] and [tex]JK[/tex] are nothing but the distance of the point [tex]K[/tex] from the end points [tex]H[/tex] and [tex]J[/tex] which are proved to be equal to each other.
Therefore, we can conclude that:
[tex]K[/tex] is equidistant from [tex]H[/tex] and [tex]J[/tex].
