Answer:

value of (b) will be: 9

Step-by-step explanation:

Answer:

b = 9

Step-by-step explanation:

(-3x² + 5x - 2) - 2(x² - 2x - 1) =

= -3x² + 5x - 2 - 2x² + 4x + 2

= -5x² + 9x

= ax² + bx + c

a = -5; b = 9; c = 0

Answer: b = 9

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Step-by-step explanation:

10)We have to calculate the average speed if we know the distance and time that Johnatan can jog. The distance

distance=3 2/5 miles = 3.4 miles.

Time=7/8 hour = 0.875 h

Then we will use the formula for the average speed ( velocity )

velocity=distance/time. v = 3.4 m / 0.875 h = 3.866 mph

so therefore The average speed is 3.866 mph.

11) divide 120 / 7/4 (remember 120 = 120/1)

Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).

Then 120x4= 480

And 1x7 = 7

Then you get 480/7, which is the same as 68 4/7 mph

12)8 1/3=25/3

   25/3 pages of a book in 10 minutes

   Multiply both numbers by the reciprocal of 10, which is 1/10

  25/3 x 1/10=25/30=5/6

  10 x 1/10=1

So, Charlotte reads 5/6 pages of a book in 1 minute.

13)45 1/2% = 45.5% = 45.5/100 = 91/200

30 1/4% = 30.25% = 30.25/100 = 121/400

75 1/3% = 75.3333...% = 75.333.../100 = 11/15

Answer:

At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F

Step-by-step explanation:

At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F

When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F

Elevation after the submarine dove = -502.5 - 115 = -617.5 feet

This negative sign represents the elevation below the sea level.

And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}

                                              = \frac{253}{4}-\frac{11}{5}

                                              = \frac{1265-44}{20}

                                              = \frac{1221}{20}

                                              = 61\frac{1}{20}°F

Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F

The required expression is y = 0.01x +  58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.

It is the relationship between sets of values. e g y=f(x),

Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as  y = - 0.01x +  58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
                      = 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F

Thus, the required expression is y = 0.01x +  58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

cause 12 divided by 3

The total Weight blocks maria has is 15.2 pounds.

A fraction represents a part of a whole.

Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.

Each full block weight \(3\frac{8}{9}\) pounds

We need to find the Weight blocks maria has

Let us convert the mixed faction to improper fraction

35/9 = \(3\frac{8}{9}\)

As there are 4 full cement, blocks

So multiply 4 with  \(3\frac{8}{9}\)

4×35/9

4×3.8

15.2

Hence,  the total Weight blocks maria has is 15.2 pounds.

Answer:

9 times

Step-by-step explanation:

The number 15 multiplied to the number 9 which gives the value 135.

To find the that how many 15 is to get 135, division should be performed.

So, dividing 135 by 15 gives:

= 135 ÷ 15

                         15 | 135 | 9

                                135

                            _______

                                   0

Thus, the quotient is 9.

Therefore, 15 goes into 135 exactly 9 times.

x = \(x < \frac{7}{2}\)

Step-by-step explanation:

convert the mixed numbers to an improper fraction:

\(\frac{1}{3} x - 3 < - 1 \frac{5}{6}\)

multiply both sides of the inequality by 6:

\(2x - 18 < - 11\)

move the constant to the right-hand side & change its sign:

\(2x < - 11 + 18\)

calculate the sum:

\(2x < 7\)

divide both sides of the inequality by 2:

\(x < \frac{7}{2}\)
