Answer:

-3x-5 x-4 I this work good luck

Answer:

-(3x-5) (x-4)

Step-by-step explanation:

-3x^2+17x-20

Factor -1 out of -3x^2

-(3x^2)+17x-20

Factor -1 out of 17x

-(3x^2)-(-17x)-20

Rewrite -20 as -1(20)

-(3x^2)-(-17x)-1(20)

Factor -1 out of -(3x^2)-(-17x)

-(3x^2-17x)-1(20)

Factor -1 out of -(3x^2-17x)-1(20)

-(3x^2-17x+20)

Factor.

-((3x-5)(x-4))

Final Anwser:

-(3x-5) (x-4)

Answer:

It is growth and the percentage rate of increase is 7.5%

Step-by-step explanation:

The exponential equation is as follows;

y = 550(1.075)^x

Now, I can identify that the exponential equation is that of growth.

This is because what is in the bracket i.e can be represented as 1+ 0.075

The 0.075 represents the margin of increase as we move on from one value to another

The percentage rate can be gotten by expressing 0.075 as a percentage

That would be expressing is as a fraction

This is just 7.5/100 which means what we have is 7.5%

Answer: 3 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a cone = 1/3 x π x radius^2 x height  

Replacing with the values given:  

75 = 1/3(3.14) r^2 (6)  

Solving for r:

75 / (1/3 (3.14) 6) = r^2

75/ 6.28 = r^2

11.94 = r^2

√11.94 =r

3.45 inches = r

3 inches = r

Feel free to ask for more if needed or if you did not understand something.  

Answer:

Change in temperature was 12 degrees

Step-by-step explanation:

If you start with five degrees and end into negative 7 degrees, you can find the result within two steps

5 degrees minus 5 = 0 degrees

then, 0 degrees minus 7 = -7 degrees

Because you subtracted 5 from five, and 7 from seven, you add those two values together

7 + 5 = 12 degrees

So the change in temperature was 12 degrees

Hope this helps!

Answer:

6.5 * 10 ^ -9

Step-by-step explanation:

0.0000000065

Scientific notation means a* 10 ^b

where a  is number between 1 and less than 10

Move the decimal  9 places to the right which means the power of 10 is negative since we moved the decimal to the right

6.5

The power of 10 is -9

6.5 * 10 ^ -9

Answer:

6.5 * 10^-9 metres.

Step-by-step explanation:

This is < 1 so the exponent is negative

We count the number of digits after the decimal point up to and including the first digit > 0.

This is 9 digits.

So the answer is 6.5 * 10^-9.

Answer:

V≈2,080cm^3  Hope I helped :)

Step-by-step explanation:

The volume of a cone of radius r and height h is:

V=1/3πr^2h

Since the circumference of Cam's head is 56

2πr=56

r=56/2π

r=28/π

The volume of the hat is therefore:

​V=1/3π(28/π )^2(25)

V=1/3((28)^2/π)(25)

V=1/3(19,600/π)

V≈2,080cm^3

The volume of the Cam's hat measured in cubic centimetres is 2081 cm³

The volume of a cone is as follows:

where

h = height

r = radius

The circumference of the part of his head where the hat will rest is 56 cm. Let's find the radius

h = 25 cm

V =  1 /  3 × π × (28 / π )² × 25

V =  1 / 3 × π × 784 / π² × 25

V = 19600 / 3π

V = 19600 / 9.42

V = 2080.67940552

V ≈ 2081 cm³

Answer:

(x+5)²(x²+5)

Step-by-step explanation:

Given two functions x²+5 and x²+10x+25, to get their Lowest common factor, we need to to first factorize x²+10x+25

On factorising we have:

x²+5x+5x+25

= x(x+5) +5(x+5

= (x+5)(x+5)

= (x+5)²

The LCM can be calculated as thus

| x²+5, (x+5)²

x+5| x²+5, (x+5)

x+5| x²+5, 1

x²+5| 1, 1

The factors of both equation are x+5 × x+5 × x²+5

The LCM will be the product of the three functions i.e

(x+5)²(x²+5)

This hives the required expression.

Answer: True

Step-by-step explanation: The angles given are the same AND the side given us the same. The triangle has been reflected, but the reflection is still congruent.

The two triangles given are congruent according to the ASA congruence rule.

Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of the other triangle.

The given triangles are both right angled triangles.

The side 12 units is the included side between the angles 45° and 90° in both the triangles. This is the required condition for ASA congruence rule.

Hence we can say that the triangles are congruent according to the ASA congruence rule. The answer is A.True.

Step-by-step explanation:

look at the number to the right of the decimal. if the number is higher than or is 5 round the number up, but if the number is less than 5 it will stay the same.

The number after rounding off to nearest hundred-thousandth or  5 decimal places will be -

3.44571

We have the following number - 3.44570830811

We have to round it of nearest hundred-thousandth or 5 decimal places.

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. For example - 53 rounded to the nearest ten is 50.

According to the question, we have the following number -

3.44570830811

Rounding it off One by one until we get 5 digits after decimal -

R1 -  3.44570830811

R2 - 3.4457083081

R3 - 3.445708308

Start by subtracting 2 from both sides.

This gives us -3x < 9.

Now, divide both sides by -3.

However, when you divide both sides of an inequality by a negative number, you must switch the direction of the inequality sign.

So we have x > -3.

Answer:

12/5hours=2.4 hours

Step-by-step explanation:

Sam:6hours

Tom:4hours

This is a rate problem

Sam's rate is one job completed in 6 hours which is 1/6

Tom's rate is one job completed in 4 hours which is 1/4

Together, they could complete 1/4+1/6 of the job in y hours

We are trying to find the rate at which Sam and Tom could complete the job together, or one job in x days, for a rate of 1/y

1/4+1/6=1/y

The least common denominator is 12y

Multiplying through by the LCD which gives:

12y(1/4)+ 12y (1/6)= 12y (1/y)

3y + 2y=12

5y = 12

y=12/5 hours=2.4hours

Therefore it will take 12/5 hours or 2.4 hours to complete the job if they work together

Answer:

The zeros of the polynomial are x = 7 or x = -11/2

Step-by-step explanation:

The zeros of a polynomial refers to the solution of the polynomial.

6x^2 + 19x -77

6x^2-14x+ 33x -77

2x(x-7) + 11(x-7)

= (2x + 11)(x-7)

2x + 11 = 0

x-7 = 0

2x = -11

x = -11/2 = -5.5

and x-7 = 0

x = 7

So the zeros of the polynomial are x = 7 or x = -11/2
