Which of the following is equivalent to the expression below? 9^10*9^x

Answer:

B) y=0

Step-by-step explanation:

The exponential function shown has a horizontal asymptote at the line y=0, which means that y will approach 0 as the value of x decreases. Therefore, B is correct.

Answer: V= 330.513 cm 3

Step-by-step explanation:

Area = l x w and with a square the length and width are the same, additionally the volume of a pyramid can be found by using the formula (L)(w)(h)/3 so

8.7 x 8.7 = 75.69cm^2

75.69 x 13.1 = 991.539

991.539 ÷ 3 = 330.513 cm^3

Answer:

True

Step-by-step explanation:

same numbers on both sides = equivalent expression

1+2+4 = 7

7-5 = 2

So the first side is 2

-5 + 4 = -1

-1 + 2 + 1 = 2

So the second side is 2

Simplified, this is 2 = 2

This is TRUE because this is an equivalent expression,  demonstrated by the equal sign.

Answer:

270 m^2

Step-by-step explanation:

1. Write down your formula.  It is V= 1/3 Bh

2. Plug in your numbers.  Your new formula is V= 1/3 (81)(10)

3. Simplify the expression to get 270.

Answer:

Angle T = 28, h = 18

Step-by-step explanation:

HW/ER = WT/RD Thales Theorem

10/5 = h/9 Substitution

2 = h/9 Alg

h = 18 Alg

Angle D = Angle T Similarity definition

Angle D + Angle E + Angle R = 180 Angle Sum Property

Angle D + 86 + 66 = 180 Substitution

Angle D + 152 = 180 Alg

Angle D = 28 Alg

Angle D = Angle T = 28 Similarity Definition

Hope this helped!

Answer:

Step-by-step explanation:

direction=y-component/x-component

tan theta =6/-1

tan theta=-6

theta=[tex]tan^{-1}[/tex]-6

theta=180 -80.53

theta=99.47°

therefore the direction of the given vector line is 99.47°

Answer:

x = 16.4

Step-by-step explanation:

For right-angle triangles, we can use the trigonometry equations;

In this case, we need to use the sine equation in particular:

sinθ = opposite/hypotenuse

sin(66) = x/18

x = 0.91...(18)

x = 16.4438... ⇒ 16.4

Answer:

x = 33 degree

Step-by-step explanation:

angles of a triangle = 64 degree , 50 degree , 2x

64 + 50 + 2x = 180 degree (sum of interior angles of a triangle)

114 +  2x = 180

2x = 180 - 114

x = 66/2

x = 33 degree

to find 2x

=2*33

=66 degree

33

Answer:

In a pyramid, line segment AD is the perpendicular bisector of triangle ABC on line segment BC. If AB = 20 feet and BD= 7 feet, find the length of side AC.

Step-by-step explanation:

Solution

It is given that AD is the perpendicular bisector on the line segment BC.

So, By Perpendicular Bisector Theorem, any point on line segment AD is at an equal distance from points B and C. It implies, AB = AC

AC = 20 feet.

Answer: 100

Step-by-step explanation:

Since she had a mean score of 94 in her 5 tests, then the total score will be:

= 94 × 5

= 470

Since she She remembered getting scores of 97, 88, 90, and 95, for 4 quizzes out of 5 quizzes, the total of the four quizzes will be:

= 97 + 88 + 90 + 95

= 370

Then, her 5th quiz will be:

= 470 - 370

= 100

Answer:

[tex]7.5\ units^2[/tex]

Step-by-step explanation:

The formula to find the area of a trapezoid is the following,

[tex]A=(h)(\frac{(b_1)+(b_2)}{2})[/tex]

Where ([tex]h[/tex]) represents the heights of the trapezoid, ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.

One is given all of these values in the picture,

[tex]h = 2.5\\\\b_1 = 2\\\\b_2 = 4[/tex]

Substitute these values into the formula and solve for the area of the trapezoid,

[tex]A=(2.5)(\frac{(2)+(4)}{2})[/tex]

Simplify,

[tex]=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5[/tex]

Answer:

r ≈ 7.9 inches

Step-by-step explanation:

V(cylinder) = πr²h

196 = πr²(1)

196/π = r²

62.4 = r²

√62.4 = r

r ≈ 7.9

Answer:

Step-by-step explanation:

take 60 degree as reference angle

using cos rule

cos 60 = adjacent / hypotenuse

1/2 = 80/x

do cross multiplication

Step-by-step explanation:

The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

Note: The second expression must be [tex][(-3)+(-7)]+(-6)[/tex] instead of [tex][3+(-7)]+(6)[/tex]

Given:

The given expression is:

[tex]-3+[(-7)+(-6)][/tex]

Rahal rewrites the expression as:

[tex][(-3)+(-7)]+(-6)[/tex]

To find:

The property that Rahal use to rewrite the expression.

Solution:

According to the associative property of addition, if a, b and c are three real numbers, then

[tex]a+(b+c)=(a+b)+c[/tex]

We have,

[tex]-3+[(-7)+(-6)][/tex]

Using the associative property of addition, we get

[tex]-3+[(-7)+(-6)]=[(-3)+(-7)]+(-6)[/tex]

Therefore, the required property is associative property of addition.

Answer:

S = 50w + 75

Step-by-step explanation:

After each week, Mike gains $50.

Letting w = 0 gives us the amount he started with. In this case, that would be $75.

Therefore, the equation is S = 50w + 75.
