Answer:

A

Step-by-step explanation:

Take test score from Test 1 and add them all together and divide by the number of test

ex) 77+82+69+85+93=406

    406/5= 81.2

Then repeat with Test 2

ex) 75+76+71+68+72=362

    362/5= 72.4

Therefore the MAD of Test 1 > MAD of Test 2

the answer is A.

Step-by-step explanation:

Add the test scores of the first test together then add the test scores of the second test together then compare and contrast.

Step-by-step explanation:

a1 = 27

r = -9/27 = -⅓

the formula :

an = a1. r^(n-1)

= 27. (-⅓)^(n-1)

= 3³(-3`¹)^(n-1)

= 3³(-3)^(1-n)

Step-by-step explanation:

Answer:

A: 46 meters at 3 seconds

B: 0 meters at 6.033 seconds

C. It depends where the tree is

D. 6.033 seconds

Step-by-step explanation:

A. To find max height, we need to find the vertex.

We can do this by using vertex from y=a(x-h)+k for y=a^2+b^2+c^2

h(t) = -5t^2+30t+1

h(t)+45 = - 5x^2+30x+45+1

h(t)+45= -5(x^2-6x-9)+1

h(t)+45 = -5(x-3)^2+1

h(t) = -5(x-3)^2+46

Hence, the max height is 46 at 3 seconds

B. The minimum height is 0 meters because of the problem

C. It depends because the parabola intersects x=10 in 2 places meaning that you need the tree to be in either of these two places to intercept the horseshoe

D. -5x^2+30x+1=0

     5x^2-30x-1=0

     x=  (30+-sqrt(30^2-4*5*-1))/2*5

     x=(30+-sqrt920)/10

     x=3+-2sqrt230/10

     x=3+-sqrt230/5

      This means that x =  -0.033  or 6.033. Negative value doesn't make sense so it's 6.033 seconds

Answer:

G

Step-by-step explanation:

vertex formula = a(x-h)^2 + k

vertex is (h, k) so (-1, -4) means

y = a(x+1)^2-4

passes through (1, 8) so when x = 1 and y = 8

8 = a(1+1)^2-4 = 4a - 4

4a = 4

a = 1

Answer:

C and D

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line

m = [tex]\frac{3+6}{9+3}[/tex] = [tex]\frac{9}{12}[/tex] = [tex]\frac{3}{4}[/tex]

Using (a, b ) = (9, 3 ) , then

y - 3 = [tex]\frac{3}{4}[/tex] (x - 9) → C

Using (a, b ) = (- 3, - 6 ), then

y - (- 6) = [tex]\frac{3}{4}[/tex] (x - (- 3) ) , that is

y + 6 = [tex]\frac{3}{4}[/tex] (x + 3) → D

Step-by-step explanation:

The volume of the rectangular prism can be found using the 6x6x7 option (A) 6x6x7 is correct.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

It is given that:

A rectangular prism is given in the picture with dimensions:

As we know, volume can be defined as a three-dimensional space enclosed by an object or thing.

The volume of the rectangular prism is given by:

V = L×W×H

Here, V is the volume of the rectangular prism

L is the length of the rectangular prism

W is the width of the rectangular prism

H is the height of the rectangular prism

From the figure:

L = 6 cm

W = 7 cm

H = 6 cm

V = 6x7x6

or

V = 6x6x7

Thus, the volume of the rectangular prism can be found using the 6x6x7 option (A) 6x6x7 is correct.

Answer:

[tex] \displaystyle b)y = { 3}^{ - x} + 1[/tex]

Step-by-step explanation:

we are given a exponential function

[tex] \displaystyle y = {3}^{x} + 1[/tex]

we want to figure out the equation of the new graph reflected across the y-axis

remember that,

[tex] \rm\displaystyle (x,y) \xrightarrow{ \text{ reflection over y - axis}}( - x,y)[/tex]

let y be [tex]3^x+1[/tex] so,

[tex] \rm\displaystyle (x,y) \xrightarrow{ \text{ reflection over y - axis}}( - x, {3}^{ - x} + 1 )[/tex]

hence,

the equation of the new graph

[tex] \displaystyle y = { 3}^{ - x} + 1[/tex]

[tex]\sf\implies{x^{2}=7^{2}+7^{2}~~~~~~~~(Pythagoras~theorem)}[/tex]

[tex]\sf\implies{x^{2}=49+49}[/tex]

[tex]\sf\implies{x^{2}=98}[/tex]

[tex]\sf\implies{x={\sqrt{98}}}[/tex]

[tex]\sf\implies{x={\sqrt{49×2}}}[/tex]

[tex]\sf\implies{x={\underline{\boxed{\sf{\pmb{7{\sqrt{2}}}}}}}}[/tex]

using Pythagorean theorem

a²+b²=c² where 'a'&'b' are legs of the right angle triangle and 'c' is the hypotenuse of the right angle triangle

here two legs are given (7,7) and x is the hypotenuse

=>a²+b²=c²

=>7²+7²=x²

=>x²=49+49

=>x²=98

=>√x²=√98

=>x=7√2

I hope it helps have a great day

Answer:The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

Answer:

x ≤ 205.05

Step-by-step explanation:

x = dollar amt remaining for other books

30 + 14.95 + x ≤ 250

44.95 + x ≤ 250

x ≤ 205.05

x ≤ $205.05 is an inequality that correctly describes this situation.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Let's use x to represent the amount of money Ms. Edwards can spend on other books.

We know that Ms. Edwards can spend at most $250 in total and that she will already spend $30 + $14.95 = $44.95 on the reference books on birds and planets.

Therefore, the amount she has left to spend on other books is:

x = $250 - $44.95

x = $205.05

Ms. Edwards can spend up to $205.05 on other books.

To write this as an inequality, we can use the less than or equal symbol since Ms. Edwards cannot spend more than $205.05:

x ≤ $205.05

Therefore, the inequality that correctly describes this situation is:

x ≤ $205.05
