Journal Write a subtraction problem involving

Mathematics
1 answer:
AleksandrR [38]2 years ago

Answer:

Problem: 5.24 - 4.93

Step-by-step explanation:

You subtract just like a normal Addition problem however you MUST make sure the decimal point line up,...

5.24\\4.93\\

1st: subtract the 3 from the 4 [0.01]

2nd: subtract the 9 from the 2 (make the 2 a 12 (by carrying a one from the 5 (which then becomes a 4))) [0.30]

3rd: Finally subtract the 4 from the 4,... 0

<em>Answer = 0.31,...</em>

A more summed up answer: Subtracting (and adding for that matter) decimals happens exactly like normal. However you MUST MAKE SURE that your decimal points are lined up,... if you are subtracting a 0.09 from a 4.5 and the 4.5 doesn't have a hundredths place just remember that you can add a 0 on the end (4.50) without chancing it's value. (and then just subtract like normal)

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5). Describe the ste
olga_2 [115]
1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.

2. So f(x)=(x-a)^{3}

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions: 
 
f(x)=b(x-a)^{3}

4. Now, f(0)=-5 so  -5=f(0)=b(0-a)^{3}=b(-a) ^{3}=-ba ^{3}

-5=-ba ^{3}

5=ba ^{3}

b= \frac{5}{ a^{3} }

5. the function is f(x)=\frac{5}{ a^{3} }(x-a)^{3} where a can be any real number except 0

What is the measure of angle 1?<br> 20°<br> 42°<br> 138°<br> 160°
nikdorinn [45]

Step-by-step explanation:

line s || line t

r is the transversal,

Therefore,

(7x-2)°= (6x+18)° {exterior alternate angles}

7x-6x=18+2

x=20°

r is also a straight line,

therefore,

7x-2+angle1=180° (straight angle)

7x-2+ angle1=180°

7(20)-2+ angle 1= 180°

140°-2+ angle 1= 180°

angle 1= (180-140+2 )°= 42°

angle 1= 42°

Circle A has an area of 452.16 ft^2 with a radius of 12 ft. If circle B has a radius of 17 ft, what is its area?
Dmitry [639]
To find this answer, you would need to use the equation for area of a circle, or in this case, a=3.14x289, since 3.14 is pi and 289 is your radius squared. giving you a final answer of 907.46 feet squared.

10 points! Hurry please!!
bulgar [2K]

Answer:

a = 0.25

r = 4

n = 5

Step-by-step explanation:

Given series is,

0.25 + 1 + 4 + 16 + 64

Ratio of 2nd and 1st term = \frac{1}{0.25}

                                          = 4

Ratio of 3rd and 2nd terms = \frac{4}{1}

                                             = 4

There is a common ratio 'r' = 4

First term of the given geometric series 'a₁' = 0.25

n = Number of terms in the series

n = 5
