The lateral area is [tex]LA=125\ in^{2}[/tex]

Step-by-step explanation:

we know that

The lateral area of a right prism is equal to

[tex]LA=PH[/tex]

where

P is the perimeter of the base of the prism

H is the height of the prism

in this problem we have

[tex]P=25\ in[/tex]

[tex]H=5\ in[/tex]

substitute

[tex]LA=(25)(5)=125\ in^{2}[/tex]

Answer:

16.67

Step-by-step explanation:

3x² - 10 = 40

3x² = 40 + 10

x² = 50

x = 50 / 3

x = 16.67

Answer:

±5√6 / 3

Step-by-step explanation:

3x² - 10 = 40

3x² = 50

x² = 50/3

x = ±√(50/3)

x = ±5 √(2/3)

Writing in proper form:

x = ±5 (√2 / √3) × (√3 / √3)

Answer:

90% increase.

Step-by-step explanation:

Percent change in altitude = (difference in altitude * 100) / original altitude

= (95-50) * 100 / 50

= 90%.

Answer:

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.

Step-by-step explanation:

Initial altitude, = 50 ft

Final altitude, = 95 ft

Increase in altitude = 95 - 50 = 45 ft

Percentage increase

              [tex]=\frac{45}{50}\times 100=90\%[/tex]

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.

Answer:

C. [tex]N(t)=150\cdot 3^t[/tex]

Step-by-step explanation:

You are given the exponential function [tex]n(t)=ab^t.[/tex]

From the table, [tex]N(t)=150[/tex] at [tex]t=0,[/tex] thus

[tex]N(0)=a\cdot b^0\\ \\150=a\cdot 1\ [\text{ because }b^0=1][/tex]

Also [tex]N(t)=450[/tex] at [tex]t=1,[/tex] thus

[tex]N(1)=a\cdot b^1=a\cdot b.[/tex]

Since  [tex]a=150,[/tex] substitute it into the second equation

[tex]450=150\cdot b\\ \\b=\dfrac{450}{150}\\ \\b=3[/tex]

and the expression for the exponential function is

ANSWER

[tex]g(x) = (4 {x)}^{2} [/tex]

EXPLANATION

We were given that,

[tex]f(x) = {x}^{2} [/tex]

Let

[tex]g(x) = a \times f(x)[/tex]

Or

[tex]g(x) = a {x}^{2} [/tex]

The point (1,16) is on the graph of g(x), hence it must satisfy its equation:

This implies that,

[tex]a {(1)}^{2} = 16[/tex]

[tex]a = 16[/tex]

We substitute the value of 'a' to get,

[tex]g(x) = 16 {x}^{2} [/tex]

Or

[tex]g(x) = (4 {x)}^{2} [/tex]

Answer:

the Ratio between the small and big triangles is that of b. [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

We can solve this ratio problem by using the Rate of Change formula as shown below,

[tex]\frac{y2-y1}{x2-x1}[/tex]

In this situation y would be the smaller triangle and x would be the larger triangle. Since all the values are given to use we can just plug those values in and solve for the rate of change / ratio.

[tex]\frac{4-3}{12-9} = \frac{1}{3}[/tex]

So the rate of change or ratio between the small and big triangles is that of [tex]\frac{1}{3}[/tex]

Answer:

AB = (2+2√3)r

Step-by-step explanation:

All three sides of an equilateral triangle equals 60° each.

Given that the circles are equal and are inscribed in a triangle, the angle bisectors pass right through the center of the circle present in front of that angle.

For example a figure has been attached with the answer, where angle bisectors make a triangle with center of the circle and a perpendicular projection of the center on side AB.

Finding AB:

Let us divide the side AB into three parts. One is the line joining the center of the two circles which is = 2

Then we have two equal parts, each joining one vertices with the center of the circle.

Let us assume that there is a point P on the side AB which forms a line segment PO₁ ⊥ AB.

We have the right angled triangle APO₁. Angle A = 30°    PO₁ = r

let the base AP = x

We know that tan 30° = perp/base

1/√3 = r/x

=> x = √3  r

Hence Side AB = √3  r + 2r + √3  r

AB = (2+2√3)r

For this case, we have by definition that, the median of a set of numbers is the average number in the set, after the numbers have been ordered from lowest to highest. If there is an even number in the set, the median is the average of the two middle numbers.

So, the given set is:

{4,5,5,6,10,11,12,13}

Since there are 8 numbers, the set is even. Then we find the average of the two numbers in the middle:

[tex]\frac {6 + 10} {2} = \frac {16} {2} = 8[/tex]

The median is 8

First Rhonda makes a 20% down payment.  20% of $85 is:

0.20 × $85 = $17

So what's left is:

$85 - $17 = $68

So the number of monthly payments at $8 per month is:

$68 / 8 = 8.5

Rounding up, it will take 9 months to make all the payments.  If her father's birthday is on the third Sunday of June, she needs to make her ninth and final payment on June 1.  So her first monthly payment needs to be 8 months before that, or October 1.

EXPLANATION

The given trigonometric equation is:

[tex] { \tan}^{2} x + 1 = { \sec}^{2} x[/tex]

We take the LHS and simplify to arrive at the RHS.

[tex]{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x}{{ \cos}^{2} x} + 1[/tex]

Collect LCM on the right hand side to get;

[tex]{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x + {\cos}^{2} x}{{ \cos}^{2} x} [/tex]

This implies that

[tex]{ \tan}^{2} x + 1 = \frac{1}{{ \cos}^{2} x} .[/tex]

[tex]{ \tan}^{2} x + 1 = {( \frac{1}{ \cos(x) }) }^{2} [/tex]

This identity has been verified .Therefore the correct answer is true.

Final answer:

The equation tan²(x) + 1 = sec²(x) is true and is derived from the fundamental Pythagorean trigonometric identity.

Explanation:

The statement tan²(x) + 1 = sec²(x) is true. This is based on a well-known trigonometric identity from mathematics.

In trigonometry, the Pythagorean identity for tangent and secant states that:

tan²(x) + 1 = sec²(x)

Which comes from the primary Pythagorean identity:

sin²(x) + cos²(x) = 1

by dividing each term by cos²(x) and recognizing that:

tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x).
