Write the equation in standard form for the given circle.

Answer:

12cm squared

Step-by-step explanation:

The area of a triangle is 1/2bh

A = 1/2 x 4 x 6

A = 4 x 3

A = 12 cm squared

Answer:

The answer is B: 12 cm^2.

Step-by-step explanation:

The formula for the area of a triangle is b * h / 2 (base times height divided by two).

6 * 4 = 24

24 / 2 = 12

And since we're looking for area, the answer would be squared, as all areas are.

The answer: 12 cm^2.

Brainliest would be really really greatly appreciated!!!!

Answer:

x=5

Step-by-step explanation:

We need to find the value of x the given equation: 3x-2=x+8

the goal when solving for equations is to isolate the variable onto one side, and have the number (value of what x is) on the other side

here's the equation:

3x-2=x+8

first, add 2 to both sides

3x-2=x+8

   +2   +2

___________

3x=x+10 (2 goes away on the left side, as -2+2=0)

now, subtract x from both sides

3x=x+10

-x   -x

______

2x=10 (x goes away on the right side, as x-x=0)

we have the variable isolated on one side, with the number on the other, but we need the value of x by itself (1x)

divide both sides by 2

x=5 (because 2x/2=1x, or x. 10/2=5).

therefore, the value of x is 5

Hope this helps!

Answer:

[tex]Z=-1.2[/tex]

Step-by-step explanation:

From the question we are told that:

Normal distribution [tex]x=35[/tex]

Mean of normal distribution [tex]\=x=65[/tex]

Standard normal distribution deviation [tex]\sigma= 25[/tex]

Generally the equation for standardized value is mathematically given by

 [tex]Z=\frac{x-\=x}{\sigma}[/tex]

 [tex]Z=\frac{35-65}{25}[/tex]

 [tex]Z=\frac{35-65}{25}[/tex]

 [tex]Z=-1.2[/tex]

Therefore the standardized value of x is

 [tex]Z=-1.2[/tex]

Answer:

A) 283500 ft³

B) 1057.26 π in³

Step-by-step explanation:

A) Volume of square based pyramid

= 1/3 × Area of the base × height

= 1/3 × (90 ft)² × 105 ft

= 283500 ft³

B) This figure is a composite figure

Step 1

Find the volume of the cone

=1/3 πr²h

r = radius = 8.5 in

h = height = 10 in

= 1/3 × π × (8.5 in)² × 10 in

= 240.83333333 π in³

≈ 240.83 π in³

Step 2

Find the volume of the cylinder

= πr²h

= r = radius = 8.5 in

h = height = 11.3 in

= π × (8.5 in)² × 11.3 in

= 816.425 π in³

≈ 816.43π in³

Volume of the figure = (240.83 π + 816.43 π) in³

= 1057.26 π in³

Answer:

21.4 miles (Answer A)

Step-by-step explanation:

17 miles west and then 13 miles south can be represented by a triangle whose leg lengths are 17 miles and 13 miles respectively.  We use the Pythagorean Theorem to find the length of the hypotenuse of this triangle; the hypotenuse length is the straight line distance between starting and end points:

d = √(13² + 17²) miles, or d = 21.4 miles

Answer:

(4.36x10^7)x(5.6x10^4)

Step-by-step explanation:

To answer the question what is 43600000 in scientific notation let’s recall how to convert 43600000 to scientific notation as detailed on our home page.

When you split the number 43600000 into a coefficient and a power of 10 you do get 43600000 in exponential form, but there is an indefinite number of possibilities.

As you probably want 43600000 in normalized scientific notation, the coefficient or significand of 43600000 in scientific notation must be in the interval [1,10[.

As there are many ways to express 43600000 in scientific notation, in this post we mean 43600000 in normalized scientific notation, unless stated otherwise. Therefore:

43600000 in scientific notation = 4.36 × 107.

Now you can do that for the other one to found out what it is equal to.  

Answer:

78$

Step-by-step explanation:

3 adults, 2 dollars per adult. Multiply. 3(2) = 6

9 children, 8 dollars per child. Multiply. 9(8) = 72

Add to get total sum of money they needed to pay. 72+6 = 78

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

Explanation:

12.32 rounds to 12.3 when rounding to the nearest tenth (aka one decimal place). The digit in the tenths place stays the same because the next digit over is not 5 or larger.

7.636 rounds to 7.6 when following the same rule

Adding those two rounded values gets us 12.3+7.6 = 19.9

The expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (x + 4)²

Simplify the expression, then we have

⇒ (x + 4)²

⇒ (x + 4)(x + 4)

⇒ x² + 8x + 16

Thus, the expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

A straight line = 180 degrees.

Answer:

Function 2 has larger max value.

Step-by-step explanation:

We know that the graph of Function 1 has the maximum value of 1 at x = 4 by looking at the graph.

But since we don't know what the maximum value of Function 2 is (Because Function 2 isn't given as a graph but rather an equation.) which means that we have to find the maximum value of Function 2.

[tex] \large{f(x) = - {x}^{2} + 4x + 1}[/tex]

It is not necessary to find x-value for a function because we want to know which function has larger maximum value. We will be using the formula below.

[tex] \large \boxed{y = \frac{4ac - {b}^{2} }{4a} }[/tex]

As you may know, a max-min value is indeed y-value. From Function 2, we know the value of a, b and c from standard form y = ax²+bx+c

Substitute our a, b and c in the formula.

[tex] \large{y = \frac{4( - 1)(1) - {(4)}^{2} }{4( - 1)} } \\ \large{y = \frac{ - 4 - 16}{ - 4} } \\ \large{y = \frac{ - 20}{ - 4} = 5}[/tex]

Since our maximum value or y-value is 5 for Function 2. Since we also know that Function 1 has 1 as maximum value and Function 2 has 5 as maximum value. Therefore, Function 2 has larger maximum value.

CH: is a radius. C is the center of the circle.

LM: You have to draw in LM. LM would be a secant. It cuts the circle in exactly two places.

CJ: Anything coming from C and ending at the circumference is going to be a radius.
