Find the area of the isosceles triangle.​

Answer:

  D.  Graph D

Step-by-step explanation:

The  "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.

Only one graph has a dashed line with shading below: Graph D.

A corollary needs theorem to be proven true.

" A corollary is defined as the statement which either need little explanation or no explanation to prove true. It is based on already proven statements."  

According to the question,

Inverse is not consider as already proven statement. It is function which needs to calculate.

Hence, Inverse is not true.

Identity are formula which is not a geometric term.

Hence , identity is not true.

Theorem are geometric term, which can be used to prove other statements true as it is already proved.

Hence, corollary needs theorem to be proven true.

Common notion are like postulates which are consider as without proof. Common notion are not limited to geometry.

Hence, common notion is not true.

Therefore, A corollary needs theorem to be proven true.

Answer:

a. Maurice walked farther.

b. 0.62 m

Step-by-step explanation:

Maurice

4.1 × 1.8 = 7.38 miles

Junnie

2.5 × 3.2 = 8 miles

This shows that Junnie walked more than Maurice.

8 - 7.38 = 0.62

Junnie walked 0.62 m more than Maurice

Answer:

17.60

Step-by-step explanation:

Look at the room carefully, the length of the room is 11 feet

And the height = 10 feet

The area of the 4 walls of the room = 4( 11×10) = 440 sq ft

Area covered by each roll = 25 sq ft

= 440/25 = 17.60 rolls

Therefore we require 17.60 rolls to cover a rectangular room on all four sides.

An odd function is a function of a form [tex]y=x^n[/tex] where n is an odd number.

Some examples would be functions:

[tex]y=x,y=x^3,\dots[/tex].

A formal definition of odd function is the following.

(Algebraic proof).

Let [tex]f:\mathbb{R}\to\mathbb{R}[/tex] (real function).

The function is odd if the below equation is true for all x and -x for which the function is defined:

[tex]f(x)=-f(-x)[/tex].

Answer:

Step-by-step explanation:

real number can be irrational or integer.

otherwise there is no number which can be irrational,integer and real (all together)

Answer: The answer is B) there is no such number.

Step-by-step explanation:

So we have to find which number is irrational, and integer, and a real number. Let's examine the problem closely:

- irrational means not rational and cannot be represented by a simple fraction (like pi )

- an integer means a number that can be written without a fractional component ( -1, 2, 0, -10000 )

- and a real number means that it is not imaginary ( like 2i, [tex]\sqrt{-1}[/tex] )

And our choices here are:

-  -4/2

-  there is no such number

Let's take a look at -4/2. This number is a fraction, but it can be simplified down to -2/1, which is an integer. -2 is a real number, not an imaginary number. But, -2 is not irrational, because as it just was shown here, it CAN be represented by a fraction. So, since only two out of the three criteria are true, then we have to consider choice B.

Answer:332

Step-by-step explanation:

Answer:

2/7

Step-by-step explanation:

Since multiplication fractions is just multiplying all numerators together and all denominators together, we can group all these fractions together into one big fraction as they are all being multiplied together:

(2x3x4x5x6x)/(3x4x5x6x7)

Because each term is being multiplied together, if it also appears in the denominator, they will cancel each other out (as x multiplied by y and then divided by y is just x as the ys cancel each other out)

Therefore we are just left with 2/7.

Answer:

KE = 900,000t²

Step-by-step explanation:

The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;

m is the mass of the sport car = 2000kg

v is the velocity of the car

Since v = at

v = 30t

Substituting the given values into the KE formula;

KE  1/2 * 2000 * (30t)²

KE = 1000*900t²

KE = 900,000t² Joules where t is the time measured in seconds

Answer:

KE = 900,000t²

Answer:

x= 11

Step-by-step explanation:

(7x -1)° + (9x +5)°= 180° (adj. ∠s on a str. line)

7x -1 +9x +5= 180

16x +4= 180 (simplify)

16x= 180 -4 (-4 on both sides)

16x= 176 (simplify)

x= 176 ÷16

x= 11

The sum of the angles on a straight line is 180°

[tex]a_n = 2S - a_1[/tex]

Step-by-step explanation:

Given

[tex]S = \frac{a_1 + a_n}{2}[/tex]

Required

Determine the formula for [tex]a_n[/tex]

What this question implies is to solve for [tex]a_n[/tex]

[tex]S = \frac{a_1 + a_n}{2}[/tex]

Multiply both sides by 2

[tex]2 * S = \frac{a_1 + a_n}{2} * 2[/tex]

[tex]2 S = a_1 + a_n[/tex]

Subtract [tex]a_1[/tex] from both sides

[tex]2S - a_1 = a_1 - a_1 + a_n[/tex]

[tex]2S - a_1 = a_n[/tex]

[tex]a_n = 2S - a_1[/tex]

Hence; the formula to solve [tex]a_n[/tex] is [tex]a_n = 2S - a_1[/tex]

Answer:

To test the effects of the multi-vitamin, we must test it on people with short-term memory loss. So the population should be people with short-term memory loss. The independent variable is the multi-vitamin and the dependent variable is the short term memory state of the people being tested. A control group can consist of people with short-term memory loss NOT being treated by the multi-vitamin.
