Please Hurry ASAP:) The magnitude and direction of two vectors are shown in tbe diagram. What is the magnitude of their sum? Will Mark Brainliest and look at the picture to answer.​

Given that:

we should find the indefinite integral of integral -2x^-10 -2 dx using C as contstant of integration

so,

integral of (-2x^a - 2) = -2/(a+1)x^(a+1) - 2x + C

Where a is the exponent of x

we have our exponent of x as -10 from the question

so,

integral of -2x^-10 - 2

= -2/(-10+1)x^(-10+1) - 2x + C

= 2/9x^(9) - 2x + C

= (2/9x)^-9 - 2x + C

The Emily soccer team has the higher ratio of wins to losses.

Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.

The ratio of a and b is denoted as a : b.

Given that,

Ratio of win to loss of Emily soccer team = 9 : 12

Ratio of win to loss of Grant soccer team = 10 : 15

9 : 12 = 9 / 12 = (9 × 5) / (12 × 5) = 45 / 60

10 : 15 = 10 / 15 = (10 × 4) / (15 × 4) = 40 / 60

If 60 games are losses, then 45 games are wins for Emily soccer team.

If 60 games are losses, then 40 games are wins for Grant soccer team.

Higher ratio is for Emily soccer team.

Hence higher ratio of wins to losses is for Emily soccer team.

Answer:

68°

Step-by-step explanation:

Total angle in a quadrant = 90°

x + 22° = 90°

x = 90 - 22

x = 68°

Part (a)

It's not stated, but I'm assuming that RV = VQ

If so, then we use the tangent ratio to connect the opposite side PV = 7 and adjacent side RV = 16

Focus on triangle RPV

tan(angle) = opposite/adjacent

tan(R) = PV/RV

tan(x) = 7/16

x = arctan(7/16) ...... same as inverse tangent

x = 23.6293777 ...... which is approximate

Rounding to the nearest degree, the angle x is roughly 24 degrees.

Since 18 < 24 < 27, this means the roof pitch follows the safety guidelines.

====================================================

Part (b)

Again we only focus on triangle RPV

We have two pathways we can take. The first option is to use the pythagorean theorem

a^2+b^2 = c^2

c = sqrt(a^2 + b^2)

PR = sqrt( (RV)^2 + (PV)^2 )

PR = sqrt( (16)^2 + (7)^2 )

PR = 17.464249 .... approximate

PR = 17.5

----------

The second path you could take is to use the angle x we found in part (a). Use either the cosine or sine ratios like so

sin(angle) = opposite/hypotenuse

sin(x) = PV/PR

PR = PV/sin(x)

PR = 7/sin(23.6293777)

PR = 17.464249

PR = 17.5

The pathway for cosine will look almost identical to this, but you'll be computing PR = RV/cos(x) instead.

Step-by-step explanation:

To answer this question we must understand what does each percentge mean :

For 71 percent alcohol we have the quantity wich is 15 liter

so :

15 liter⇒ 100 percent

x( the unkhown quantity)⇒ 71 percent

x = (15*71)/100 )= 10.65 liter of alcohol

so we want 10.65 liter of alcohol

here is a way :

lat's take 10 L of 80 percent alcohol and 4liters of  the other one

10*0.8+4*0.65 = 10.6

we just need 0.05 liter of alcohol

add 0.0625 L of the 80 percent liter alcohol to get 10.65

Start with the first two columns, taking every possible pair of True/False for p and q.

¬q is just the negation of q, so True becomes False and False becomes True.

p ∨ q is the logical disjunction, or logical "or". It's True if either p or q is True, and False otherwise. So p ∨ ¬q is True only if either p or ¬q is True.

p ⇒ q is the logical implication. It's True only when both p and q are True, or when p is False. So (p ∨ ¬q) ⇒ q is True when both p ∨ ¬q and q are True, or when p ∨ ¬q is False.

The 83% confidence interval for the difference in the proportion of dishes sent back to the Ruby team and the Sapphire team is (0.1344, 0.2579). The point estimate is 0.1962 and the margin of error is 0.0618.

a. The point estimate of the difference in the proportion of dishes sent back to the Ruby team and the Sapphire team is:

p₁ - p₂ = (175/207) - (71/203) = 0.1962

b. To find the critical value, we first need to calculate the degrees of freedom:

df = (207-1) + (203-1) = 408

Using a t-distribution with 408 degrees of freedom and a confidence level of 83%, we find the critical value to be:

tc = 1.2554

c. The margin of error is given by:

ME = tc [√[(p₁ [q₁ / n₁]) + (p₂ [q₂ / n₂])]]

where q₁ and q₂ are the complements of p₁ and p₂, respectively. In this case:

q₁ = 1 - p₁ = 1 - 175/207 = 32/207

q₂ = 1 - p₂ = 1 - 71/203 = 132/203

Substituting the values, we get:

ME = 1.2554 [√[(175/207 [32/207 / 207]) + (71/203 [132/203 / 203])]] ≈ 0.0618

Therefore, the 83% confidence interval for the difference in the proportion of dishes sent back to the Ruby team and the Sapphire team is:

0.1962 ± 0.0618, or (0.1344, 0.2579)

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

we can write:

tan(55 degrees) = 32 / d

To solve for "d", we can rearrange the equation:

d = 32 / tan(55 degrees)

Using a calculator, we can evaluate the tangent of 55 degrees:

tan(55 degrees) = 1.428

d = 22.4 meters

Therefore, the car is approximately 22.4 meters away from the tower.

The rate of interest charged by the bank on the principal amount is 12.36%.

The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR (APR).

A savings account or certificate of deposit earnings at a bank or credit union may also be subject to an interest rate (CD). The interest received on these deposit accounts is measured in annual percentage yields (APY).

Given that,

Principal = 740

Interest payment = $15

Overdue days = 59

The rate of interest charged is calculated using the following formula:

R = 15 / Principal × 360 / days overdue

R = 15 / 740 × 360 / 59

R = 12.36%

Hence, the rate of interest charged by the bank on the principal amount is 12.36%.

The volume of a solid formed by revolving the region bounded above by the line is (932π/15)

To use the disk method, we need to integrate over the axis of revolution, which is the y-axis in this case. We can break the solid into vertical disks of thickness dy.

The radius of each disk is given by the distance between the y-axis and the curve \(x = y^2 - 1\). So the radius is:

\(r = y^2 - 1\)

The height of each disk is the difference between the y-coordinate of the top curve y = 3 and the y-coordinate of the bottom curve y = 1. So the height is:

h = 3 - 1 = 2

The volume of each disk is then:

\(dV = \pi r^2h dy\)

Substituting r and h, we have:

\(dV = \pi (y^2 - 1)^2 (2) dy\)

To find the total volume, we integrate over the range of y from 1 to 3:

\(V = \int_{1}^{3} \pi(y^2 - 1)^2 (2) dy\)

This integral can be simplified by expanding the squared term:

\(V = \int_{1}^{3} \pi (y^4 - 2y^2 + 1) (2) dyV = 2\pi \int_{1}^{3}(y^4 - 2y^2 + 1) dyV = 2\pi [(1/5)y^5 - (2/3)y^3 + y]^3_1\)

V = \(2\pi [(1/5)(3^5 - 1^5) - (2/3)(3^3 - 1^3) + (3 - 1)]\)

V = 2π [(1/5)(242) - (2/3)(26) + 2]

V = 2π [(242/5) - (52/3) + 2]

V = 2π [(726/15) - (260/15) + 30/15]

V = 2π [(466/15)]

V = (932π/15)

Solution of the equation 6x−5(6x+39)=−75 is x=5.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

We have the equation,

6x−5(6x+39) = −75.

In order to solve the equation for x:

We will find the value of x.

First, we solve parenthesis.

6x−5(6x+39) = −75

6x - 30x - 195 = -75

Taking constant terms to the right side of the equation,

6x - 30x = 195 - 75

To write the expressions in standard notation we need to follow this rule:

• When we multiply by a power of 10 we will move the decimal point to the right if the exponent of the 10 is a positive number and to the left, if the exponent of the 10 is a negative number.

We start with the first expression:

Since the exponent of 10 is negative, we will move the decimal point to the left. And we move it the number of times that the exponent indicates: 4

The following image shows the result after moving the decimal place:

As you can see we have moved the decimal point 4 places to the left and it is important to fill the spaces with 0.

Thus:

Now we solve the second expression:

Again the exponent of 10 is negative so we will move the decimal point to the left the number of times the exponent indicates: 3 times.
