Nala is escaping from the dragon's lair! She is running toward the entrance of the lair at a speed of 9.29.2 meters per second. The entrance is 180180 meters away. The distance dd between Nala and the entrance of the lair is a function of tt, the time in seconds since Nala began running. Write the function's formula.

Answer:

∠NET = 63°

Step-by-step explanation:

We are given a figure with a circle A and a line ET which is tangent to the circle at the point T. Also, the measure of the angle TNG is given to be 27° and we are to find the measure of angle NET.

If we recall the point of tangency, we will remember that the point where a tangent touches the radius of a circle is always a right angle.

That makes the angle NTE to be 90°.

Putting the sum of these angles equal to 180 to get:

90 + 27 + ∠NET = 180

∠NET = 180 - 90 - 27

∠NET = 63°

Answer: Third option (bottom left)

Step-by-step explanation: We want to find which one of the graphs is the graph of the function f(x) = 4*2^x

Let's analyze some interesting points.

f(0) = 4*2^0 = 4*1 = 4

So we need to find the graph that passes through the point (0,4) (this means that intercepts the y-axis in the 4)

The graph that passes through the point (0,4) is the third option (bottom left one)

The slope of the equation x + 2y = 4, is -1/2 and y-intercept of the equation is 2.

When any equation is represented in the y = m x +c form, it is called the slope intercept form of the equation.

Here m is slope and c is constant.

The given equation of line,

x + 2y = 4,

To find the slope,  represent the equation in slop intercept form,

Simplify the equation,

x + 2y = 4

2y = -x + 4

y = -(1/2)x + 2

The slope of the equation is -1/2.

To find y-intercept, substitute x = 0,

y = -(1/2). 0 + 2

y = 2

The y-intercept of the equation is 2.

Final answer:

The equation in slope-intercept form for the total cost C of a pizza with t toppings when a pizza costs $12 and each additional topping costs $1.50 is C = 1.50t + 12.

Explanation:

To find the equation in slope-intercept form for the total cost C of a pizza with t toppings at a pizza parlor that charges $12 for a large cheese pizza and $1.50 for each additional topping, we can establish a relationship between the number of toppings and the total cost. Let's use the slope-intercept form of the linear equation, y = mx + b where y is the total cost, m is the cost per topping, x is the number of toppings, and b represents the base price of the pizza without toppings.

The base price of the pizza is $12, which is the y-intercept, and the additional cost per topping is $1.50, which is the slope. Therefore, the equation that represents the total cost C of the pizza with t toppings is:

C = 1.50t + 12

Step-by-step explanation:

Bonnie deposits $70.00 into a new savings account.

The account earns 45% simple interest per year.

She neither added or removed from the savings account for 3 years.

We know that,

[tex]i=\dfrac{P\cdot r\cdot r}{100}[/tex]

here,

i = interest,

P = principal = $70,

r = rate of interest = 45%,

t = time = 3 years,

Putting the values,

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

One way is to graph the function f(x) = ln(x)/(x-1) and you'll see the curve slowly approach y = 1 when x approaches 1 from either side. Check out the attached image labeled "figure 1" for this graph.

---------

You can use a table to see this in action. See figure 2 (attached below as well).

-----------

Another alternative is to use L'Hospital's rule. This is because we get the indeterminate form 0/0 after plugging x = 1 into the original function.

if y = ln(x), then dy/dx = 1/x

If y = x-1, then dy/dx = 1

So f(x) = ln(x)/(x-1) becomes (1/x)/1 = 1/x

If you plug in x = 1, you get 1/x = 1/1 = 1.

Regardless of which method you use, the limiting value is 1

F(-4) = -3313

Step-by-step explanation:

To solve this, let x=-4

f(x) = 3x^5 + 4x^3-x+11

f(-4) = 3(-4)^5 + 4(-4)^3 -(-4) +11

     = 3(-1024) +4 (-64) +4+11

    = -3072 - 256+15

     = -3313

We know that : Sin²θ + Cos²θ = 1

Given : Sinθ [tex]\bf{= \frac{4}{7}}[/tex]

[tex]\bf{\implies (\frac{4}{7})^2 + Cos^2(\theta) = 1}[/tex]

[tex]\bf{\implies Cos^2(\theta) = 1 - \frac{16}{49}}[/tex]

[tex]\bf{\implies Cos^2(\theta) =(\frac{33}{49})}[/tex]

[tex]\bf{\implies Cos(\theta) = (\pm)(\frac{\sqrt{33}}{7})}[/tex]

Given : θ lies in Quadrant II

We know that : Cosθ is Negative in Quadrant II

[tex]\bf{\implies Cos(\theta) = (-)(\frac{\sqrt{33}}{7})}[/tex]

Option 3 is the Answer

Answer:

None of the Above

Step-by-step explanation:

As it is given that

cosФ= 3/2

and Ф lies in quadrant 4

Now in quadrant 4 we know that by the rules of trigonometry that

cos Ф is positive in 4th quadrant also in 4th quadrant

and sinФ is negative in 4th quadrant

also we know that by simple rules of trigonometry in a right angled triangle

cos Ф=[tex]\frac{Base}{Hypotenuse}[/tex] =[tex]\frac{3}{2}[/tex]

now from the law of trigonometry

cos²Ф+sin²Ф=1

From this we derive the value of sinФ

solving the equation

sin²Ф=1-cos²Ф

Putting in the values of cos Ф

sin²Ф=1-[tex](\frac{3}{2})^{2}[/tex]

sin²Ф=1-[tex](\frac{9}{4})[/tex]

solving the fraction

sin²Ф=[tex](\frac{4-9}{4})[/tex]

sin²Ф=[tex](\frac{-5}{4})[/tex]

so taking square root of both sides

[tex]\sqrt{sin^{2}\alpha}=\sqrt{\frac{-5}{4} }[/tex]

here

[tex]\alpha[/tex]=Ф

so it becomes

sin Ф=[tex]\frac{\sqrt{-5} }{2}[/tex]

as we know that in imaginary numbers

[tex]\sqrt{-1}[/tex] = ι

so the given becomes

sin Ф=[tex]\frac{{-5ι} }{2}[/tex]

Which is the value of sin Ф

And in the given values we can see that it is none of the values

Also seeing the question we can see that the question is absurd because

cos Ф= base / hypotenuse

in our question we can see that base =3 and hypotenuse = 2

but in real geometry this is the rule that hypotenuse can never be smaller then base either it is equal to base or greater then base

the formula for finding value of finding hypotenuse is

hypotenuse ² = base ² + perp ²

so this formula shows that if perp is 0 then hypotenuse will be equal to base

in other cases it would be greater then base

Step-by-step explanation: cause your fine

A scale factor of 1/2 makes the triangle half the size of the original.

The original is 4 units tall, so 1/2 scale makes the new one 2 units tall.

It is 6 units long, so 1/2 would be 3 units long.

Now since the scale factor is centered at (-1,3) fine the midpoint between The top left corner of the triangle and the center point:

Midpoint ( -1-5/2 , 3+7/2)

Midpoint = (-6/2 , 10/2)

Midpoint = -3,5

This is where the top left corner of the scaled triangle would be.

Final answer:

The blanks are filled with 'straight line' as angles on a straight line sum to 180°, which is a key concept in geometry related to the properties of angles and triangles.

Explanation:

The sum of the measures of angle 5 and angle 6 is equal to 180° and the sum of the measures of angle 2 and angle 3 is equal to 180° because angles on a straight line measure 180°. This concept is related to the geometric property that when two angles lie on the same line and add up to form a straight angle, their measures sum up to 180°.

In geometry, specifically the study of polygons and angles, we learn that a triangle is a three-sided figure lying on a plane with three angles adding up to 180°. This is called the Triangle Sum Theorem, which is fundamental to understanding the properties of triangles and other polygons.

Answer:

Let x represents the ounces of first spice.

From the given statements, you draw a table as shown below:

                           ounces of spice         Percentage           ounces of salt

First spice                 x                              3%                            0.03x

Second spice           175                            6%                          175(0.06)

Final  mixture          x+ 175                         5%                        (x+175)(0.05)

Now, to solve for x;

Final spice = First spice + second spice

[tex]0.03x+175(0.06) = (x+175)(0.05)[/tex]

[tex]0.03x + 10.5 = 0.05x + 8.75[/tex]

Subtract 10.5 on both sides we have;

[tex]0.03x + 10.5 -10.5= 0.05x + 8.75-10.5[/tex]

Simplify:

[tex]0.03x= 0.05x -1.75[/tex]

Subtract 0.05x on both sides;

[tex]0.03x - 0.05x= 0.05x -1.75-0.05x[/tex]

Simplify:

[tex]-0.02x= -1.75[/tex]

Divide both sides by -0.02, we get;

x = 87.5 ounces

Therefore, 87.5 ounces of spices i.e 3% salt should be added to 175 ounces of a spice that is 6% salt in order to make a spice that is 5% salt

Area of triangle = 30 unit²

Step-by-step explanation:

By distance formula distance between (a,b) and (c,d) is [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]

So, we have

      [tex]AB=\sqrt{(16-2)^2+(2-8)^2}=15.23\\\\BC=\sqrt{(16-6)^2+(2-2)^2}=10\\\\AC=\sqrt{(2-6)^2+(8-2)^2}=7.21[/tex]

Perimeter = 15.23 + 10 + 7.21 = 32.44 unit

We have [tex]s=\frac{15.23+10+7.21}{2}=16.22[/tex]

Area of triangle[tex]=\sqrt{s(s-AB)(s-BC)(s-AC)}=\sqrt{16.22(16.22-15.23)(16.22-10)(16.22-7.21)}=30[/tex]

Final answer:

Roasted beans retain 3/5 of their initial weight, which is equivalent to 60% when converted to a percent.

Explanation:

To convert this fraction to a percentage, we follow the steps outlined in the explanation: dividing the numerator by the denominator to get a decimal value, and then multiplying by 100 to express it as a percentage. In this case, 3 divided by 5 equals 0.60, which when multiplied by 100 gives 60%.

The roasted beans retain approximately 3/5 of their initial weight after roasting. To determine what percentage of their initial weight they retain, we convert the fraction 3/5 to a percent. To do this:

Therefore, roasted beans retain 60% of their initial weight.

[tex]4csc(2x) = 2csc^2(x) tan(x)[/tex]

We start with Left hand side

We know that csc(x) = 1/ sin(x)

So csc(2x) is replaced by 1/sin(2x)

[tex]4 \frac{1}{sin(2x)}[/tex]

Also we use identity

sin(2x) = 2 sin(x) cos(x)

[tex]4 \frac{1}{2sin(x)cos(x)}[/tex]

4 divide by 2 is 2

Now we multiply top and bottom by sin(x) because we need tan(x) in our answer

[tex]2\frac{1*sin(x)}{sin(x)cos(x)*sin(x)}[/tex]

[tex]2\frac{sin(x)}{sin^2(x)cos(x)}[/tex]

[tex]2\frac{1}{sin^2(x)} \frac{sin(x)}{cos(x)}[/tex]

We know that sinx/ cosx = tan(x)

Also  1/ sin(x)= csc(x)

so it becomes 2csc^2(x) tan(x) , Right hand side
