Answer:

See below

Step-by-step explanation:

7)  a rectangle   12 x 8 = 96

     plus semi-circle   1/2  pi r^2 = 1/2 pi 4^2 = 25.132

          total = 121.132 m^2

8)  Circle area = pi r^2

       large circle   pi * 2^2  = 4pi

            MINUS the smaller one   pi 1.5^2 = 2.25 pi

                    total = 1.75 pi = 5.498 in^2

9) Square area = 10 x 10 = 100

      minus circle  pi r^2 = 25pi      total = 21.46  ft^2

Answer:

  (b)  1/3

Step-by-step explanation:

A function "zero" is a value of x that makes the value of the function be zero. It may also be called a "root" of the function. On a graph, it is an x-intercept.

The zeros are the solutions to the equation f(x) = 0. For a quadratic like the one given, there are two of them. For this function, they are distinct, so one will be larger than the other.

There are a number of ways the solutions to this equation can be found. Technology, in the form of a graphing calculator, can show you the x-intercepts easily (see attached). They are x=-2/5 and x=1/3.

We can also factor the equation. Doing this requires that we find factors of the product (15)(-2) = -30 that have a sum equal to the coefficient of x, +1. Here are some factor pairs:

  -30 = (-1)(30) = (-2)(15) = (-3)(10) = (-5)(6)

The corresponding sums are 29, 13, 7, 1. Hence the last factor pair, {-5, 6}, is the one we need.

Rewriting the 3-term polynomial to a 4-term polynomial by splitting the middle term using these factors, we have ...

  15x² -5x +6x -2 = 0

Factoring pairs of terms gives ...

  5x(3x -1) +2(3x -1) = 0

  (5x +2)(3x -1) = 0 . . . . . . . factor out the common factor

The product of these factors can only be zero of one of them is zero. (This is the "zero product rule.") Setting the factors to zero, we find the values of x that make f(x) = 0: the zeros of the function.

  5x +2 = 0   ⇒   x = -2/5

  3x -1 = 0   ⇒   x = 1/3

The zeros of the function are -2/5 and 1/3.

The larger zero is 1/3.

Answer:

1. Time (hours): 1     Distance (miles): 45

2. 1;45

  2;90

  3;135

  4;180

  5;225

  6;270

3. (c= constant of proportionality)

c= [tex]\frac{distance}{time}[/tex]

c=[tex]\frac{90 miles}{2 hours}[/tex]

c= 45 miles per hour

Step-by-step explanation:

So you may see for each hour they are going 45 miles by dividing 2 by 2 and 90 by 2, so there constant of proportionality is 45 miles per hour. (answer 3 is the step by step)

Answer:

5446 cm²

Explanation:

Area of triangular prism = Base × Height + Length × (perimeter of base)

Here given:

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

Solve for Surface Area = 24 × 35 + 47 × (98) = 5446 cm²

1. SA = P*L/2. As it's a square pyramid, P = 7*4 = 28 yd and SA = 28*4/2 = 28*2 = 56 sq yd.

2. SA = 2B+ph

B = area of the base (3*7 = 21), p = perimeter of the base (6+14=20), h = height (2)

==> 2B+ph = 42+22 = 64 sq. ft

3. SA = (Perimeter of the base × Length of the prism) + (2 × Base Area) = 32+10 * 16 + 2 * 80 = 32 + 160 + 160 = 320 + 32 = 352 sq. cm

4. SA = 6l^2 = 6*64 = 384 sq. in

5. Analogue to 1, SA = (7*4*5)/2 = (28*5)/2 = 14*5 = 70

Answer:

87.92 in^3

Step-by-step explanation:

Formula for finding the volume of a cylinder:

V=Bh

B= area of the base

h= height

Diameter=4 radius=2 The radius is half of the diameter

The base of a cylinder is a circle, so you would find the area of the circle and multiply it by the height of the cylinder.

V= (3.14*2^2)7

V= (3.14*4)7

V= 12.56(7)

V= 87.92 in^3

Answer:

The answer to this question should be b. 87.92 in^3 because the formula to find the volume of a cylinder is V=TTr^2h. and remember that the radius is half of the diameter so back to the question.

We multiplied 3.14 times 4 because remember that the radius is half of the diameter and we get 2 but remember the exponent so we need to multiplied to the second power 2 times 2 and we get 4 so when we multiplied 3.14 times 4 we get 12.56 and when we multiplied 12.56 times the height which is 7 we get 87.92 so check the choices and see if there is an answer and yes there is so b which is 87.92in^3 is hopefully the correct answer.

                          Im pretty sure its d

Answer:

B.

Step-by-step explanation:

To dilate is to make something bigger. It says in the question that you dilate by a factor of 2, so multiply the length of the side by 2. This will get you 68.

As far as angles are concerned, angles do not change when the object is scaled bigger. So for the angle of A, the answer is still 28 degrees.

This leaves us with our final answer, which is B.
