Someone please help me with this math problem! :(

The formula for this area is basexheight so you have to mutiply (2x+3)x(ax+5) and this multiplication must be equal to 8x^2+bx+15. If you do the multiply and then equalization you will get 2ax^2+10x+3ax+15 = 8x^2+bx+15.
Now is easy to see that 2ax^2 must be equal to 8x^2 so 2a=8 you solve for a and you get a=4. The same step for b you have 10x+3ax= bx so 10+3a=b as you know now a is 4 so 10+12=b you solve for b and you get b=22.
The answer is a=4 and b=22 

How to solve this math question

(2x - 1) + (x + 4) = 12

2x - 1 + x + 4 = 12

3x + 3 = 12

3x = 12 - 3

3x = 9

x = 3

Can you help with 5 math multiple question their easy

1. yes because they go into it equally
2. 2 3 4 5 9 10
3. 3 5 9
4. 300 and 400 because 100 x 3 is 300 and 4 x 100 is 400
5. 9000 and 5000 because 9 x 1000 is 9000 and 5 x 1000 is 5000

A fossilized leaf contains 15% of its normal amount of carbon 14. How old is the fossil (to the nearest year)? Use 5600 years as the half-life of carbon 14. Solve the problem. A. 35,828 B. 15,299 C. 1311 D. 21,839

Answer:

Option B - 15299

Step-by-step explanation:

Given : A fossilized leaf contains 15% of its normal amount of carbon 14. Use 5600 years as the half-life of carbon 14.

To find : How old is the fossil (to the nearest year)?

Solution :

Let the normal or initial amount of carbon be A,

According to the question,

An exponential function form f(t)=ab^t

Where, a is the initial i.e, a=A

A fossilized leaf contains 15% of its normal amount of carbon 14.

So, f(t)=15% of A

i.e, f(t)=0.15A

b is half-life of Carbon-14 b=0.5

and t is the time span or age of the fossil in years.

Substitute all the values in the formula,

0.15A=A(0.5)^t

\frac{0.15A}{A}=(0.5)^t

0.15=(0.5)^t

Taking log both side,

\log(0.15)=t\log(0.5)

t=\frac{\log(0.15)}{\log(0.5)}

t=2.73

For 5600 years the age of the fossil is t=2.73\times 5600=15288

Therefore, Approximately Option B is correct.

The fossils are 15299 years old.


Spectroscopy measurements may be made in either percent transmittance (% t) or absorbance ( a. based on the mathematical relationship between absorbance and transmittance, a= -log t, explain why calibration curves of absorbance versus concentration may deviate from a straight line when a<0.1 and when a>1.

Calibration curves absorbance versus concentration may deviate from a straight line when A<0.1 and when A>1 maybe because at these values the substances react to light differently which will cause it to not follow a linear graph. Hope this helps. Have a nice day.

Explain how you could use the distributive property and mental math to find 5×198

Well divide the number 198 by two so you have two numbers to distribute to. Well the mental math part you use pencil and paper or just take the easy route and use a calculator.

How to be best in math?

You must practice maths every day. Practice more and more sums which you have find difficulties.
Means you have to practice, practice and practice.
Practice makes a man perfect.

I'm having trouble with graphs and tables and equations.. I'm in math 1 and need help filling out the table (y=3x-1) I have to graph it after and I really need help getting the y output

Really simple. Just input several x values into the equation t get the y values (output) for example if x=1 then y= 3(1) -1 which is 2. So one of your coordinates would be (1,2). 

Let's say we want to find when x=5. Then y would be y=3(5)-1 which would be 14. Our next coordinate to graph would be (5,14)

Hope I helped!



What is the value of n in math

In mathematical n is a variable and its is often found in Equations for accounting

A student scored an 88, 92, and 76 on three math tests. What does the student need to get on the fourth test to have an average of 85 for all four tests? James wants to use algebra to solve this problem. Which equation should he use?

Answer: The student need to get 84 marks in the fourth test to have an average of 85 for all four tests

Step-by-step explanation:

Since we have given that

Scores of a student were

88, 92, 76 on three math tests.

Since we want an average of 85 for all four tests.

Let the score he get on fourth test of Math be x.

As we know the formula for " Average" :

Average=\frac{\text{ Sum of all observation }}{\text{ Total number of observation }}\\\\85=\frac{88+92+76+x}{4}\\\\85\times 4=88+92+76+x\\\\340=256+x\\\\340-256=x\\\\84=x

Hence, The student need to get 84 marks in the fourth test to have an average of 85 for all four tests.
