Area = 35 cm^ 2

Step-by-step explanation:

Area = 1/2(a+b) x h

1/2 (5+9) x 5

= 35 cm^ 2

Answered by G a u t h m a t h

Answer:

A = 35  cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \(\frac{1}{2}\) h (b₁ + b₂)

where h is the perpendicular height between the bases and b₁, b₂ are the bases.

Here h = 5 , b₁ = 9 and b₂ = 5 , then

A = \(\frac{1}{2}\) × 5 × (9 + 5) = 2.5 × 14 = 35 cm²

Answer:

Final Cost= 1.09(xx - .05xx)

Step-by-step explanation:

Since its 9% tax on the new price you would take the new price which would be 1.0 and add the .09 of tax. So its ×1.09 to get the tax.

The expression for the total cost is 1.09(xx-(0.05)xx).

The total cost is the amount calculated after any discount for an item and along with the tax incurred for an item to be purchased.

For the given situation,

Ethan buys an item that costs xx dollars.

He has discount coupon of 5% = 0.05

The tax percentage is 9% = 0.09

The discounted amount will get less from the cost price. So,

⇒ \(xx-(0.05)xx\)

The tax amount for the item will get added to the final cost of an item. Thus the expression becomes,

⇒ \(1.09(xx-(0.05)xx)\)

Hence we can conclude that the expression for the total cost is    1.09(xx-(0.05)xx).

This equation shows that, as volume increases, the pressure of the gas decreases in proportion.

Similarly, as volume decreases, the pressure of the gas increases.

The slope of the line forming the smallest right triangle, when a line is drawn through the point (1, 2), is 2.

The slope of the line forming the smallest right triangle with the positive x and y axes, when a line is drawn through the point (1, 2), can be determined as follows.

First, let's consider the two axes as the legs of the right triangle, and the line drawn through (1, 2) as the hypotenuse. The slope of the hypotenuse can be calculated by finding the difference in y-coordinates divided by the difference in x-coordinates between the two endpoints.

Since the x-coordinate of the point where the line intersects the x-axis is 0 (positive x-axis), and the y-coordinate of the point where the line intersects the y-axis is 0 (positive y-axis), the difference in y-coordinates is 0 - 2 = -2, and the difference in x-coordinates is 0 - 1 = -1.

Therefore, the slope of the line forming the smallest right triangle is -2/-1 = 2.

Answer:

option 3

Step-by-step explanation:

using the Sine Rule in Δ ABC

\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\) , that is

\(\frac{59.2}{sin74}\) = \(\frac{60.3}{sinC}\) ( cross- multiply )

59.2 × sinC = 60.3 × sin74° ( divide both sides by 59.2 )

sinC = \(\frac{60.3sin74}{59.2}\) , then

∠ C = \(sin^{-1}\) (\(\frac{60.3sin74}{59.2}\) ) ≈ 78.3° ( to the nearest tenth )

The statement cross-tabulation with two variables is known as twice-tabulation is false because there is no such term as "twice-tabulation" in the context of statistical analysis.

Cross-tabulation, also known as contingency table analysis, involves the analysis of categorical variables by creating a table that shows the frequency or distribution of one variable based on the levels of another variable.

It allows for the examination of the relationship between two variables, highlighting any associations or patterns that may exist. Each cell in the cross-tabulation table represents the count or proportion of observations that fall into specific combinations of categories from the two variables.

The term "twice-tabulation" does not exist in statistical literature and is not commonly used to refer to cross-tabulation with two variables. The correct term to describe this statistical technique is simply cross-tabulation or contingency table analysis.

Answer:

He would have to pay £950 to insure the bicycle.

Step-by-step explanation:

£45 = £9.50 insurance

£4,500 = \(\frac{4500}{45}\) × £9.50 insurance

            = £950

As per the given data, the man would have to pay £950 to insure his bicycle.

Insurance is a contract between an individual or entity (the policyholder) and an insurance company in which the policyholder pays a premium in exchange for financial protection against certain events or circumstances.

To calculate the cost of insurance for the bicycle, we first need to calculate how many £45 increments there are in the value of the bicycle:

Value of bicycle = £4,500

Value of each increment = £45

Number of increments = Value of bicycle / Value of each increment = £4,500 / £45 = 100

So, there are 100 increments of £45 in the value of the bicycle.

Next, we can calculate the cost of insurance by multiplying the number of increments by the cost per increment:

Cost of insurance = Number of increments x Cost per increment

Cost of insurance = 100 x £9.50

Cost of insurance = £950

Therefore, the man would have to pay £950 to insure his bicycle.

Answer:

x=7\(\sqrt{3}\), y=14

Step-by-step explanation:

Since it's a right triangle, and we know the degree is 30, so

7=sin30·y,

y=\(\frac{7}{sin30}\)=14,

\(x^{2}\)+\(7^{2}\)=\(y^{2}\).

x=\(\sqrt{14^{2}-7^{2} }\)=\(\sqrt{147 }\)=7\(\sqrt{3}\)

Answer:

x = 7\(\sqrt{3}\) , y = 14

Step-by-step explanation:

using the tangent and sine ratios in the right triangle and the exact values

tan30° = \(\frac{1}{\sqrt{3} }\) and sin30° = \(\frac{1}{2}\) , then

tan30° = \(\frac{opposite}{adjacent}\) = \(\frac{7}{x}\) = \(\frac{1}{\sqrt{3} }\) ( cross- multiply )

x = 7\(\sqrt{3}\)

and

sin30° = \(\frac{opposite}{hypotenuse}\) = \(\frac{7}{y}\) = \(\frac{1}{2}\) ( cross- multiply )

y = 14

The value of x is 7

To determine the value, we have that;

m<BC = 2 < BDC

Then, we have;

<BDC = 1/2(2x + 16)

<BDC = x + 8

Also, we have that;

m<ED = 2 < ECD

m<ECD = 1/2 (7x - 9) = 3.5x - 4.5

Bute, we have that;

<<BDC + <ECD + < DAC = 180; sum of angles in a triangle

substitute the values

x + 8 + 3.5x - 4.5 + 145 = 180

The equation of the tangent line to the circle through the point (-6,8) has equation = Y = 0.75x + 3.5

For circles that have a center at (0,0), the equation is  \(x^{2} + y^{2} = r^{2}\)

\(x^{2} + y^{2} = 10^{2}\)

\(x^{2} + y^{2}\) = 100

We check if the point (-6,8) is a circle

\(x^{2} + y^{2}\) = 100

\(-6^{2} + 8^{2}\) = 36 + 64 = 100

So the point is exactly at circle line, as picture below

We solve the gradient of a normal line (n)

Mn = \(\frac{y2 - y1}{x2 - x1}\) = \(\frac{8 - 0}{-6 - 0}\)  = \(- \frac{8}{6}\)

For perpendicular lines the gradient is

Mp = \(- \frac{1}{Mn}\)  = \(\frac{- 1 }{-\frac{8}{6} }\) = \(\frac{6}{8} = \frac{3}{4}\)

The standard equation of a linear line is

Y =  mx + c

We need to find constant (c). We substitute x and y with point (-6,8)

So, x = -6 and y = 8

C = y - mx

C = 8 - ¾(-6) = 8 – \(\frac{18}{4}\) = 3.5

With m = Mp =  \(\frac{3}{4}\) and c = 3,5    

So, Y =  mx + c

      Y =     \(\frac{3}{4}\) x + 3.5

      Y = 0.75x + 3.5

Answer:

\(\mathbf{6xe^xy+y^2e^x = C}\) which implies that C is the integrating factor

Step-by-step explanation:

The correct format for the equation given is:

\(y(6x+y +6)dx +(6x +2y)dy=0\)

By the application of the general differential equation:

⇒ Mdx + Ndy = 0

where:

M = 6xy+y²+6y

\(\dfrac{\partial M}{\partial y}= 6x+2y+6\)

and

N = 6x +2y

\(\dfrac{\partial N}{\partial x}= 6\)

∴

\(f(x) = \dfrac{1}{N}\Big(\dfrac{\partial M}{\partial y}- \dfrac{\partial N}{\partial x} \Big)\)

\(f(x) = \dfrac{1}{6x+2y}(6x+2y+6-6)\)

\(f(x) = \dfrac{1}{6x+2y}(6x+2y)\)

f(x) = 1

Now, the integrating factor can be computed as:

\(\implies e^{\int fxdx}\)

\(\implies e^{\int (1)dx}\)

the integrating factor = \(e^x\)

From the given equation:

\(y(6x+y +6)dx +(6x +2y)dy=0\)

Let us multiply the above given equation by the integrating factor:

i.e.

\((6xy+y^2 +6y)dx +(6x +2y)dy=0\)

\((6xe^xy+y^2 +6e^xy)dx +(6xe^x +2e^xy)dy=0\)

\(6xe^xydx+6e^xydx+y^2e^xdx +6xe^xdy +2ye^xdy=0\)

By rearrangement:

\(6xe^xydx+6e^xydx+6xe^xdy +y^2e^xdx +2ye^xdy=0\)

Let assume that:

\(6xe^xydx+6e^xydx+6xe^xdy = d(6xe^xy)\)

and:

\(y^2e^xdx +e^x2ydy=d(y^2e^x)\)

Then:

\(d(6xe^xy)+d(y^2e^x) = 0\)

\(6d (xe^xy) + d(y^2e^x) = 0\)

By integration:

\(\mathbf{6xe^xy+y^2e^x = C}\) which implies that C is the integrating factor

Answer: 60°

Step-by-step explanation: 180 - 120 = 60.

Answer:

30 and 150

Step-by-step explanation:

The first angle is 30 degrees. The second angle is 150 degrees. Here's why:

Explanation:

The first angle will be expressed as x. Since the second angle is 120

degrees greater than the first, it will be expressed as  (x+120). Because they're supplementary, they'll add up to

180: x+(x+120)=180

Combine like terms.

2x+120=180

Subtract 120 from both sides.

2x=60

Divide by 2 to isolate for x.

x=30

Plug your data back in:

30 + (30 + 120) = 180

First angle: 30 degrees

Second angle: 150 degrees

Answer: i think its 4

Step-by-step explanation:

Answer:

1) E(X) = 1.5

2)SD = 1.118

Step-by-step explanation:

1) Formula for expected value of this set of data is;

E(X) = Σx * P(x)

Σx = 0 + 1 + 2 + 3 = 6

And P(x) = ¼

Thus;

E(X) = 6 × ¼ = 1.5

2) Formula for the standard deviation is;

SD = √Σ((x - μ)²•P(x))

Where μ is the expected value = 1.5

At x = 0,we have;

(0 - 1.5)² × 1/4 = 0.5625

At x = 1, we have;

(1 - 1.5)² × 1/4 = 0.0625

At x = 2, we have;

(2 - 1.5)² × 1/4 = 0.0625

At x = 3, we have;

(3 - 1.5)² × 1/4 = 0.5625

Thus,Σ((x - μ)²•P(x)) = 0.5625 + 0.0625 + 0.0625 + 0.5625 = 1.25

Thus;

SD = √1.25

SD = 1.118
