Answer:

Step-by-step explanation:

The height of the kite above the ground to the nearest tenth of a foot is 84.1 ft

The situation forms a right angle triangle.

Therefore, the length of the string is the hypotenuse of the triangle formed.

Hence, using trigonometric ratios,

sin 35 = opposite / hypotenuse

sin 35 = h / 140

cross multiply

h = 140 sin 35

h = 140 × 0.57357643635

h = 80.3007010891

Height of the kite above the ground = 80.3007010891 + 3.75 = 84.0507010891

Height of the kite above the ground = 84.1 ft

Step-by-step explanation:

We are looking for the percent that represents "6 out of 625"

Divide to find the decimal answer:

6/625 means

6 ÷ 625

= 0.0096

Then multiply by 100 to change to a percent.

Answer:

i could help but i don't see the graph chart

Step-by-step explanation:

Step-by-step explanation:

there is no image here. and we don't know, if B is smaller or lager than A.

anyway, the volume of a sphere is

4/3 × pi × r³ = 4/3 × pi × r×r×r

that means the scale factor applying to r (radius) has to be multiplied in 3 times (with every r). so, to compare the volumes, the volume scale factor is cubed the linear scale factor.

44³ = 85184

if B is smaller, then its volume is 50/85184 m³

if B is larger, then its volume is 50×85184 m³

since this a such a big number, you made possibly a typo with the scale factor.

The volume of sphere B, the image of sphere A after dilation by a scale

factor of 44, is approximately 1,223,762.42 cubic meters.

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Since, The volume of a sphere is given by the formula:

V = (4/3) pi r

where V is the volume, pi is the constant 3.14.., and r is the radius of the sphere.

Since, sphere A has a volume of 50 cubic meters, we can use this formula to solve for its radius:

50 = (4/3) pi r

r = (3/4)  (50 / pi)

r = (3/(4pi) 50)^(1/3)

r = 2.67 meters

Note that we know,

The radius of sphere A, we can use the scale factor of 44 to find the radius of sphere B:

rₐ = 44  rₓ

rₐ = 44 × 2.67

rₐ = 117.48 meters

Finally, we can use the volume formula again to find the volume of sphere B:

V(B) = (4/3) pi rₓ

V (B) = (4/3) pi (117.48)

V (B) = 1,223,762.42 cubic meters

Therefore, the volume of sphere B, the image of sphere A after dilation by a scale factor of 44, is approximately 1,223,762.42 cubic meters.

Geometric sequence

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

(where a is the first term and r is the common ratio)

Given:

[tex]\displaystyle \sum^{29}_{n=2}80(1.23)^{n-2}[/tex]

The sigma notation means to find the sum of the given geometric series where the first term is when n = 2 and the last term is when n = 29.

First term (a)

Determine the first term by substituting n = 2 into the given expression:

[tex]n=2 \implies 80(1.23)^{2-2}=80[/tex]

Common ratio (r)

From inspection, the common ratio is 1.23.

nth term

As the first term is when n = 2 and the last term is when n = 29, there is a total of 28 terms.

Therefore:

Sum of the first n terms of a geometric series:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Substituting the given values into the formula:

[tex]\implies S_{28}=\dfrac{80\left(1-1.23^{28}\right)}{1-1.23}=114125.7556[/tex]

Therefore, the sum of the given geometric series is 114,126 (nearest whole number)

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

Explanation:

We'll use the following facts (either memorized or written on a reference sheet somewhere)

Each of those equations will form conversion factors to help us go from km/hr to m/s. Each conversion factor is a fraction connecting the two sides of the equation. Example: The equation 1000 m = 1 km forms the conversion factor of [tex]\frac{1000 \text{ m}}{1 \text{ km}}[/tex]

In choice B, notice how the fractions are set up. The "km" units cancel when dividing. The same goes for the "hr" and "min" units.

Check out the screenshot below where I show this cancellation in action. The color-coding helps show how the terms pair up and cancel.

Choice A comes close to what choice B is saying, but we don't have the "min" units cancel. So choice A is eliminated as an answer.

Choices C and D are also eliminated because of the "75 km" in the denominator. It should be 1 km.

Hello! In this question, we are trying to solve the expression with a given value.

__________________________________________________________

Explanation:

In this question, we were given our f(x) equation: f(x) = x² - 3

We were also given the value of our variable "x": -3

To solve the expression, we would plug in our "x" value, -3, into the "x" variables in our expression and solve.

Solve:

f(x) = x² - 3

f(-3) = (-3)² - 3

= 9 - 3

= 6

Therefore, the value of f(-3) is 6.

__________________________________________________________

Answer:

f(-3) = 6

__________________________________________________________

To solve this problem, you will substitute an existing value into a function in order to find the y-coordinate at that x-coordinate.

Given the function f(x) = x² - 3, evaluate the function at f(-3) by substituting in x = -3:

[tex]f(-3) = -3^2-3[/tex]

Use BPEMDAS, which stands for:

Brackets

Parentheses

Division

Subtraction

First, evaluate -3².

[tex]-3\times-3=9[/tex]

Then, evaluate the rest of the expression by subtracting 3 from 9:

[tex]9 - 3 = \boxed{6}[/tex]

The final answer is f(-3) = 6.

Answer:

[tex]f(x)=4\cos(2x)+3[/tex]

Step-by-step explanation:

Using the general equation [tex]f(x)=a\cos(bx+c)+d[/tex], we already know that [tex]a=4[/tex] and [tex]d=3[/tex], but we need to find [tex]b[/tex] from the period:

[tex]\frac{2\pi}{|b|}=\pi\\ 2\pi=b\pi\\2=b[/tex]

Hence, the cosine function is [tex]f(x)=4\cos(2x)+3[/tex]

Answer:

Below.

Step-by-step explanation:

This is the correct solution:

6 - 2x + 5 + 4x

= -2x + 4x + 6 + 5

= 2x + 11.

It looks like they added  unlike  terms together (4x + 5) to give 9x (incorrect)  then added the 4x to give 13x.

Vector components are expressed in the form (x, y). The measure of tan m given the coordinate Q is -√32/12

Vector components are expressed in the form (x, y). Given the  coordinates of point Q are (−12,√32), the measure of the angle is expressed as;

m = arctan(y/x)

m = arctan (-√32/12)

Take the tan of both sides

tan m = tan arctan(-√32/12)

tan m = -√32/12

Hence the measure of tan m given the coordinate Q is -√32/12

Step-by-step explanation:

we have a right-angled triangle :

the Hypotenuse (baseline opposite of the 90° angle) is the 850 ft cable from the top of the tower down to the point on the ground 360 ft away from the tower.

then the ground distance (360 ft) and the height of the tower are the 2 legs.

so, we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse.

in our case

850² = 360² + height²

height² = 850² - 360² = 592,900
