Answer 1

Answer:

(x+3)(x+2)

Step-by-step explanation:

The numbers 2 and 3 add to 5 and multiply to 6. Therefore when you put them in a factor box, you will end up with [tex]x^2+5x+6[/tex]

Answer 2
Answer : (x+3) (x+2) :

Step-1 : Multiply the coefficient of the first term by the constant 1 • 6 = 6

Step-2 : Find two factors of 6 whose sum equals the coefficient of the middle term, which is 5 .

-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7
2 + 3 = 5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 2 and 3
x2 + 2x + 3x + 6

Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+2)
Add up the last 2 terms, pulling out common factors :
3 • (x+2)
Step-5 : Add up the four terms of step
(x+3) (x+2)

Jason multiplied 1.5 by a power of ten and got 150. What power of ten did he multiply by?

Answers

Answer:

Jason multiplied 1.5 by the whole number 10.

Step-by-step explanation:

As opposed to multiplying 1.5 by the tenth power, in which Jason would've received 57.66503..., he multiplied 1.5 by 10 units, resulting in a product of 150.

Hope this helps!

The power of ten did he multiply by 2.

Given that;

Jason multiplied 1.5 by a power of ten and got 150.

Let us assume that;

The value of power = x

Hence it can be written as,

1.5 × 10ˣ = 150

Divide both sides by 1.5;

10ˣ = 150/1.5

10ˣ = 100

It can be written as,

10ˣ = 10²

This gives,

x = 2

Therefore, the value of power is 2.

Answer:

3rd option

Step-by-step explanation:

Substitute x = 0 into f(x) and check if the result is - 6

f(0) = (0 + 1)(0 + 2)(0 + 3) = 1 × 2 × 3 = 6 ≠ - 6

f(0) = (0 + 1)(0 - 2)(0 - 3) = 1 × - 2 × - 3 = 1 × 6 = 6 ≠ - 6

f(0) = (0 - 1)(0 + 2)(0 + 3) = - 1 × 2 × 3 = - 1 × 6 = - 6 ✔

Thus the 3rd option crosses the y- axis at (0, - 6 )

Angle 1=87°

Angle 2=88°

angle 1+2= 177

Step-by-step explanation:

I believe thsi should be right,

So angle 1 and 87° are the same because of some rule, then the angle above 2 would be 92 because of the same rule and its a straight line so 180-92=88 making angle 2, 88. When you add those it would be 177. Try that

A shopkeeper bought a fan for rupees 840 at what price should he sell it to make a profit of 10% If he makes a loss of 5% by selling at what is the selling price​

Answers

Answer with Step-by-step explanation:

10% of 840 can be found by multiplying 840 by 0.10 (or dividing 840 by 10)

10% of 840 = 84

To make a profit of 84 he needs to sell at 840 + 84 = 924 rs

5% of 840 can be found by multiplying 840 by 0.05 (or dividing 840 by 20)

5% of 840 = 42

To make a loss of 42 he needs to sell at 840 - 42 = 798 rs

A child flies a kite at a height of 90 ​ft, the wind carrying the kite horizontally away from the child at a rate of 30 ft/sec. How fast must the child let out the string when the kite is 150 ft away from the​ child?

Answers

By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

How to determine the rate of change of the string

The geometric representation of this question is based on the Pythagorean theorem:

l² = x² + y²     (1)

Where:

x - Horizontal distance of the kite from the kite, in feet.y - Height of the kine, in feet.l - Length of the string, in feet.

The rate of change of the length of the string is obtained by differential calculus:

[tex]2 \cdot l \cdot \dot l = 2\cdot x \cdot \dot x[/tex]

[tex]\dot l = \frac{x\cdot \dot x}{l}[/tex]

[tex]\dot l = \frac{x\cdot \dot x}{\sqrt{x^{2}+y^{2}}}[/tex]    (2)

If we know that x = 150 ft, y = 90 ft and [tex]\dot x = 30\,\frac{ft}{s}[/tex], then the rate of change of the length of the string is:

[tex]\dot l = \frac{(150\,ft) \cdot \left(30 \,\frac{ft}{s} \right)}{\sqrt{(150\,ft)^{2}+(90\,ft)^{2}}}[/tex]

[tex]\dot l \approx 25.725\,\frac{ft}{s}[/tex]

By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

Identify the slope-intercept form and the graph of the line described by the equation 3x − 3y = 15.

Answers

Answer:

The slope-intercept form is y=x-5

The graph is in the picture below

Step-by-step explanation:

To find the slope-intercept you need to move y all by itself:

y=mx+b

subtract 3x on both sides:

-3y=-3x+15

Divide by -3 on both sides:

y=x-5

Hope this helps!

(Why I took two pictures is because to show you that the line is the same even with it being slop-intercept form)
