Answer:

Step-by-step explanation:

Multiply each term of (x² + 2x - 1) by x  and multiply each term of            (x² + 2x - 1) by 3

Area of parallelogram = bh

  = (x² + 2x - 1)(x + 3)

  = (x² + 2x - 1)*x + (x² + 2x - 1)*3

 =x²*x + 2x*x  - 1*x + x²*3 +2x*3 - 1*3

 = x³ + 2x² - x + 3x² + 6x - 3

 = x³ + 2x² + 3x²   -x + 6x - 3

 = x³ + 5x² + 5x - 3

Answer: c

Step-by-step explanation:

Answer:

Yes. If the third angle is equal to 115 degrees.

Step-by-step explanation:

The sum of all the angles in a triangle must equal 180 degrees.

If the two angles are 20 degrees and 45 degrees the third angle must be

180-45-20= 115 degrees

A triangle having three different angles is called a scalene triangle.

A scalene triangle also has three different sides.

But if the third angle is less or greater than 115 degrees the triangle cannot be formed.

This is the called the sum property of triangle.

There is another property which must also be satisfied i.e  the sum of any 2 sides must be greater than the third side.

Answer:

1.31

Step-by-step explanation:

I used a calculator and just rounded this number 1.30769230769

if the number is five or higher then you would round the number next to the 7. So 7 rounded 0 is 1.31. Sorry i tried to explain it in the best way possible!

Answer:

y = -2/3x + 8

Step-by-step explanation:

Format: y = mx + b

m = slope (rise over run) - 2/3 The graph is negative so the slope is also negative.

b = y - intercept (8)

Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

An easy way to figure this out is just by dividing the initial amount of students (18) by the current amount of students (24), and then subtracting 1.

So, 18/24 = 0.75 (aka 75%), and  1 - 0.75 = 0.25 (aka 25%)

Answer:

∠A=30° and AC and BC is 13 and 7.5 units respectively

Step-by-step explanation:

Given that in a right triangle ABC , right angled at C , if angle B =60 degree and AB =15 units

we have to find the remaining angles.

By angle sum property,  sum of angles in right angle is 180°

∠A+∠B+∠C=180°

∠A+ 60°+90°=180

∠A=180°-150°=30°

∠A=30°

As AB= 15

Now by trigonometric ratios we find the other sides of triangle ABC

Hence, ∠A=30° and AC and BC is 13 and 7.5 unitsStep-by-step explanation:

Answer:

by clumbing the ladder

Step-by-step explanation:

The base of the ladder should be placed so that it is one foot away from the building for every four feet of hight to where the ladder rests against the building. This is known as the 4 to 1 rule.

Answer:

Step-by-step explanation:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Answer:

The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.

P(3.9≤X≤4.3)  = 0.9922

Step-by-step explanation:

Step(i):-

Given that the mean of the Normal distribution = 4.1mm

Given that the standard deviation of the Normal distribution = 0.0075mm

Let 'X' be the random variable in a normal distribution

Given that X₁ = 3.9mm

[tex]Z_{1} = \frac{X_{1} -mean}{S.D}[/tex]

[tex]Z_{1} = \frac{3.9 -4.1}{0.075} = -2.666[/tex]

Given that X₂ = 4.3mm

[tex]Z_{2} = \frac{X_{2} -mean}{S.D}[/tex]

[tex]Z_{1} = \frac{4.3 -4.1}{0.075} = 2.666[/tex]

Step(ii):-

The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.

P(3.9≤X≤4.3) = P(-2.666≤Z≤2.666)

                     = P(Z≤2.666)-P(Z≤-2.666)

                    = 0.5 +A(2.666) - (0.5-A(2.666)

                   = 2 × A(2.666)

                 = 2×0.4961

                 = 0.9922

Final answer:-

The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.

P(3.9≤X≤4.3)  = 0.9922

Answer: 164 ft

Step-by-step explanation:

tan 48=215/x

-> x.tan48=215

->x =215/tan 48

->x = 193.6

tan 31=215/y

-> y.tan31 = 215

-> y= 215/ tan 31

-> y= 357.82

BC= y-x

= 357.82-193.6

= 164.22 = 164 ft
