Answer:
she can't finish reading the book in 10 days
Step-by-step explanation:
Given that:
Number of pages = 325
Number of pages read per day= 25
Using the linear relation:
y = mx + c
y = number of pages left
m = reading rate ; c = initial number of pages
y = - 25x + 325
Point slope relation :
y - y1 = m(x - x1)
m = slope
We can factorise the equation to the point slope form:
y - 325 = 25(0 - 10)
y - 325 = 0 - 250
y - 325 = - 250
y = - 250 + 325
y = 75
Hence, number of pages left after 10 days = 75, thus she can't finish reading the book in 10 days

f(x)=4x^2+5x-3
g(x)=4x^3-3x^2+5
Find (f-g)(x)
Answer:
For me the answer was (f+g)(x)=4x^3+x^2+5x+2
Step-by-step explanation:
A function assigns the values. The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that f(x)=4x²+5x-3 and g(x)=4x³-3x²+5, therefore, the value of the (f-g)(x) can be written as,
(f-g)(x) = f(x) - g(x)
= 4x² + 5x - 3 + 4x³ - 3x² + 5
= 4x³ + 4x² - 3x² + 5x + 5 - 3
= 4x³ + x² +2
Hence, The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.

The answer on the right bottom
Step-by-step explanation:
3/4 × 1/2 = 3/8
None of them have 3 shaded but the right bottom
Therefore that'd be your answer
Answer:
bottom right
Step-by-step explanation:
In order to know the answer, you have to find the product of [tex]\frac{3}{4}[/tex] x [tex]\frac{1}{2}[/tex].
Multiply both numerators and denominators in order to get the answer.
[tex]\frac{3}{4}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{8}[/tex] (this is the lowest term already)
If you check among the choices, it is only the bottom right choice that shows correct shading of the fraction. The diagram divides the right side into 4 equal parts. If you divide the left side into 4 equal parts like this, you'll surely get 8 equal parts of the total diagram. This represents the denominator, 8. The shaded portion represents the numerator, 3.

Carbon-14 is a radioactive isotope that has a half-life of 5,730 years. Approximately how many years will it take for carbon-14 to decay to 10 percent of its original amount?
Answer:
Carbon-14 will take 19,035 years to decay to 10 percent.
Step-by-step explanation:
Exponential Decay Function
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.
An exponential decay can be described by the following formula:
[tex]N(t)=N_{0}e^{-\lambda t}[/tex]
Where:
No = The quantity of the substance that will decay.
N(t) = The quantity that still remains and has not yet decayed after a time t
[tex]\lambda[/tex] = The decay constant.
One important parameter related to radioactive decay is the half-life:
[tex]\displaystyle t_{1/2}=\frac {\ln(2)}{\lambda }[/tex]
If we know the value of the half-life, we can calculate the decay constant:
[tex]\displaystyle \lambda=\frac {\ln(2)}{ t_{1/2}}[/tex]
Carbon-14 has a half-life of 5,730 years, thus:
[tex]\displaystyle \lambda=\frac {\ln(2)}{ 5,730}[/tex]
[tex]\lambda=0.00012097[/tex]
The equation of the remaining quantity of Carbon-14 is:
[tex]N(t)=N_{0}e^{-0.00012097\cdot t}[/tex]
We need to calculate the time required for the original amout to reach 10%, thus N(t)=0.10No
[tex]0.10N_o=N_{0}e^{-0.00012097\cdot t}[/tex]
Simplifying:
[tex]0.10=e^{-0.00012097\cdot t}[/tex]
Taking logarithms:
[tex]ln 0.10=-0.00012097\cdot t[/tex]
Solving for t:
[tex]\displaystyle t=\frac{log 0.10}{-0.00012097}[/tex]
[tex]t\approx 19,035\ years[/tex]
Carbon-14 will take 19,035 years to decay to 10 percent.
Answer:
19,035 years

Answer:
x = 7
y = 10
Step-by-step explanation:
<K and <NLK are marked as being equal.
That means that KN and LN are equal.
So LN = 6
y - 4 = 6
y = 4 + 6 = 10
For the same reason LN = LM
That means that x + 3 = 10
x = 10 - 3
x = 7

3. In the figure shown, a circle with center O and radius of length 3 units is
inscribed in a square. What is the area of the shaded region? *
A. 3.86 square units
B. 7.73 square units
C. 28.27 square units
D. 32.86 square units
Answer:
C
Step-by-step explanation:
To find the area of a circle, take its radius (3) and square it. In this case, 3 times 3 = 9. Then, you multiply the answer by pi, which rounds to 3.14, but is more like 3.14159265......etc, etc. There is a rhyme for that: May I have a large container of coffee beans? Where the length of each word is a number of pi. Anyway, most people would write 9pi, but this is asking for the exact answer, so you can do 3.14 times 9, which equals roughly 28.27. Hope this helped!

8=×
[tex] \sf{13x + 6 = 110°}[/tex]
Reason:
exterior alternate angles
[tex] \sf{13x = 110 - 6}[/tex]
[tex] \sf{13x = 104}[/tex]
[tex] \sf{x = \dfrac{104}{13} }[/tex]

Verification:
13x + 6 = 110°
13×8+6=110

The graph shows cubic polynomial.
What are Polynomial?A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are also known as indeterminates.
Given:
In the graph the number of times the graph touches the x- axis it will have that many zeroes or solution for the polynomial.
The given graph touches the x-axis three times which shows the polynomial will have three solution and the degree of the polynomial is 3.
Hence, the graph shows cubic polynomial.
