Step-by-step explanation:

11+17 x 7=130

x=130

130 is bigger than 120 but smaller than 180

Since

[tex]\csc(x)=\dfrac{1}{\sin(x)}[/tex]

we have

[tex]\csc(x)\sin(x)+\tan(x) = \dfrac{1}{\sin(x)}\cdot \sin(x)+\tan(x)=1+\tan(x)[/tex]

And since

[tex]\tan(x)=\dfrac{8}{15}[/tex]

we have

[tex]1+\tan(x) = 1-\dfrac{8}{15}=\dfrac{15}{15}-\dfrac{8}{15}=\dfrac{7}{15}[/tex]

The value of cscθ sinθ + tan θ is 7/15.

cscθ is the reciprocal of sinθ.

The expression is given by cscθ sinθ + tan θ.

We can simplify this expression before solving it.

Let the expression be y = cscθ sinθ + tan θ.

cscθ = 1/sinθ

y = sinθ * 1/sinθ + tan θ

y = 1 + tan θ

The value of tan θ is given as -8/15.

We can substitute this above:

y = 1 + tan θ

= 1 - 8/15

= (15-8)/15

= 7/15

The value of the expression cscθ sinθ+ tan θ is found to be 7/15.

Therefore, the value of cscθ sinθ + tan θ is 7/15.

Option B

same-side interior angles

Step-by-step explanation:

Given in the question, two non parallel lines a and b.

The area between lines a and b is called the interior of the two lines.

Angles 4 and 5 are same-side interior angles.

Other options are wrong because:

The area which not between lines a and b is called the exterior

Corresponding angles are on same side of the traversal line.

Angles 1 and 5

Alternate interior angles are in interior region but in opposite side of traversal line.

Answer:

120 miles

Step-by-step explanation:

we know that

The speed is equal to the distance divided by the time

Let

s------> the speed in mph

d-----> the distance in miles

t -----> the time in hours

s=d/t

solve for the distance

d=s*t

It will take Adam four hours to drive to Disney Park

s=x mph

t=4 h

substitute

d=4x -----> equation A

It will take Adam 2.5 times less time if driving 45 mph faster

so

s=(x+45) mph

t=4/2.5=1.6 h

substitute

d=1.6(x+45) -----> equation B

equate equation A and equation B

4x=1.6(x+45)

Solve for x

4x=1.6x+72

4x-1.6x=72

2.4x=72

x=30 mph

Find the distance d

d=4x -----> d=4(30)=120 miles

Answer:

120 miles

Step-by-step explanation:

The van needs 21 gallons of gas. Take 16/(320/420)

The van will need 21 gallons of gas to travel 420 miles, based on its fuel efficiency of 20 miles per gallon.

The student is asking how many gallons of gas a van needs to travel 420 miles, given that it travels 320 miles on 16 gallons of gas.

First, we calculate the van's fuel efficiency which is found by diving the miles traveled by the gallons of gas used. For the van in the question:

Fuel efficiency: 320 miles / 16 gallons = 20 miles per gallon (MPG)

Next, we can use this fuel efficiency to find out how many gallons will be needed for 420 miles. We divide the total miles by the MPG:

Gallons needed: 420 miles / 20 MPG = 21 gallons

Therefore, the van will need 21 gallons of gas to travel 420 miles.

I assume one of the four options is the correct answer...

Remember that in order to determine if a function rule is correct, you should be able to plug an x value into the equation and get the corresponding y value as the answer.

The first option, f(x) = x + 1, is correct!

Answer:  The correct option is (A) f(x) = x + 1.

Step-by-step explanation: We are given to write a function rule for the following table :

x              -1           0           1             2

f(x)           0           1            2            3

From the given table, we see that

[tex]f(-1)=0=-1+1,\\\\f(0)=1=0+1,\\\\f(1)=2=1+1,\\\\f(2)=3=2+1.[/tex]

Therefore, the required function rule is given by

[tex]f(x)=x+1.[/tex]

Thus, option (A) is CORRECT.

For this case we have to find the inverse of a function, follow the steps below:

Then, it is observed that of option 3:

[tex]f (x) = 4x[/tex]

Replace [tex]f (x)[/tex]with y:

[tex]y = 4x[/tex]

We exchange the variables:

[tex]x = 4y[/tex]

We solve for "y":

[tex]4y = x\\y = \frac {x} {4}[/tex]

Finally we change y by [tex]f ^ {- 1} (x):[/tex]

[tex]f ^ {- 1} (x) = \frac {x} {4}[/tex]

Answer:

The correct option is C

Answer:

It's the third choice.

Step-by-step explanation:

f(x) = y = 4x

x = 1/4 y

Change the y to x:

so the inverse g(x) = 1/4 x.

a. By Pythagorean Theorem: [tex]ET=\sqrt{113}[/tex]

b. By Distance Formula: [tex]ET=\sqrt{113}[/tex]

Step-by-step explanation:

The given rectangle has vertices R(-3,-4), E(-3, 4), C(4,4), and T(4-4).

The points have been plotted on the coordinate plane as shown in the attachment.

a. Using the Pythagoras Theorem;

[tex]ET^2=EC^2+CT^2[/tex]

We substitute the side lengths to obtain:

[tex]ET^2=7^2+8^2[/tex]

[tex]ET^2=49+64[/tex]

[tex]ET^2=113[/tex]

Take positive square root to obtain:

[tex]ET=\sqrt{113}[/tex]

b. The distance formula is given by:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The endpoints of ET are at E(-3,4) and T(4,-4).

Using the distance formula;

[tex]ET=\sqrt{(4--3)^2+(-4-4)^2}[/tex]

[tex]ET=\sqrt{(7)^2+(-8)^2}[/tex]

[tex]ET=\sqrt{49+64}[/tex]

[tex]ET=\sqrt{113}[/tex]

Answer:

Divide by 4p: 4px/4p=60/4p

x=15/p

Answer:

90 because it’s a right angle and a right angle it 90 degrees

Answer:

16.2

Step-by-step explanation:

A trick to remember for right triangles is SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Here, we have the side adjacent to the angle and the hypotenuse.  So we should use cosine.

cos 22° = 15 / x

x = 15 / cos 22°

x ≈ 16.2

Answer:

Step-by-step explanation:

y=mx+b

b= y-intercept

m=slope

m=-3

b=9

            [tex]\huge\boxed{Slope=-3,\;Y\;intercept=9.}[/tex]

___________________________________________________________

                                             [tex]\boxed{Explanation}[/tex]

y=mx+b.

m is always where the slope is located.

b is always where the y intercept is located.

Therefore, since -3 is located at m that is the slope and 9 is located at b so that is the y intercept.

Answer:

See below.

Step-by-step explanation:

If we translate h(x) to the left it will override  line d(x) because  the slope of both lines is the same. H(x) will need to move 4 units to the left to do this (because the slope =  2 = 8/4).

To represent the same function as d(x), the linear function h(x) with a slope of 2 should be translated 4 units to the left, resulting in the function h(x+4). This horizontal shift increases the value of y by 8 units, which equates to the vertical shift applied to create d(x).

To translate the linear function h(x) to result in the same function as d(x), which is h(x) translated 8 units up, we need to consider the properties of linear functions and translations. Since h(x) has a slope of 2, we can denote it as h(x) = 2x + b, where b is the y-intercept. When h(x) is translated 8 units up to become d(x), the new function is d(x) = h(x) + 8 = 2x + b + 8. To counteract this vertical shift with a horizontal translation and maintain the same function as d(x), we must shift h(x) in such a way that every x value for h(x) yields the same y-value for d(x) after the translation.

To achieve this, we would have to shift h(x) to the left by 4 units, resulting in the function h(x+4). This is because for every 1 unit increase in x, the value of h(x) increases by 2 units (the slope), so a shift of 4 units left would increase y by 8 units, which is the same effect as the vertical translation applied to obtain d(x). Thus, h(x+4) = 2(x+4) + b = 2x + 8 + b, which aligns with d(x). This explanation confirms that the properties of linear functions and translation mechanics allow us to equate d(x) with a horizontally translated version of h(x).

To find a set of parametric equations for the line y = 4x - 5;

We can assign either variable x or y equal to the parameter t, in this case we can easily let x = t

We then substitute x = t in the original equation;

[tex]log( \frac{14}{3} ) + log( \frac{11}{5} ) - log( \frac{22}{15} ) =\log 7[/tex]

EXPLANATION

The given logarithmic expression is:

[tex] log( \frac{14}{3} ) + log( \frac{11}{5} ) - log( \frac{22}{15} ) [/tex]

We apply the product rule to the first two terms to get:

[tex]log( \frac{14}{3} \times \frac{11}{5} ) - log( \frac{22}{15} ) [/tex]

We the apply the quotient rule:

[tex]log( \frac{14}{3} \times \frac{11}{5} \div \frac{22}{15} ) [/tex]

[tex]log( \frac{14}{3} \times \frac{11}{5} \times \frac{15}{22} ) [/tex]

We cancel out the common factors and simplify to obtain:

[tex]log( 7 ) [/tex]

Required Knowledge.

log(ab) =log(a) + log(b)

log(a/b) = log(a) -log(b)

SOLUTION

log(14/3) +log(11/5) -log(22/15)

=log((14/3)×(11/5)) -log(22/15)

=log(154/15) -log(22/15

=log( (154/15) ÷ (22/15) )

=log( (154/15) × (15/22) )

=log(154/22)

=log(77/11)

=log(7)
