One interior angle of a convex polygon (a convex polygon is a polygon where all angles
are less than 180 degrees) is 120 degrees. All the other angles are 130 degrees. How many sides
does the polygon have?

The value of X is 7.625 while the two sides are 38.125 and 27.875.

Perimeter = 2(L+B)

112 = 2(5x + 3x + 5)

112 = 2(8x + 5)

Dividing both sides by 2

56 = 8x + 5

56 + 5 = 8x

61 = 8x

x = 61/8

x = 7.625

The sides are;

5x = 5(7.625)

5x = 38.125

3x + 5 = 3(7.625) + 5

3x + 5 = 22.875 + 5

3x + 5 = 27.875

The equivalent function of the form J(t)= ab^t is J(t) = 448(16)^(t)

Equivalent functions are functions that work the same even though they look different. If two exponential functions are equivalent, then the two functions will have the same value when we substitute the same value(s) for the variable(s).

We can write the given function, (t)=28(4)^(2t+2) as:

J(t) = 28(4)^(2t+2)

J(t) = 28(4²)^(t) × 4²

J(t) = 28(16)^(t) × 16

The polynomial's zeros must be located using a method of your choice, and the linear expressions that produce those zeros must then be combined in order to describe the polynomial as a product of linear factors.

The term "triple zero" or "zero with multiplicity 3" is used to describe this. The power p governs the behaviour close to the x-intercept if a polynomial has a factor of the type (xh)p. A zero of multiplicity p is defined as x=h. The x-axis will be touched at zeros with even multiplicities on a polynomial function's graph.

A real number is multiplied by an imaginary unit, I whose feature i2 = 1 defines it as an imaginary number. Bi is an imaginary number, while b2 is its square. For instance, the square of the fictitious integer 5i is 25. Zero is regarded as both real and fictitious by definition.

You must first determine the polynomial's zeros using the method of your choice, and then combine the linear equations that result in those zeros. If you factor, you will arrive at the third degree polynomial, which must then be sorted through.

Joe made a mistake in his calculations by multiplying 28 quarts by 4.

To know the mistake that Joe made and the possible correction, we shall convert 28 quart to gallon.

Recall that 4 quart = 1 gallon

Therefore, 28 quart will be:

= 28 quart × 1 gallon / 4 quart

28 quart = 7 gallon

Therefore, 28 quarts is equivalent to 7 gallons.

Hence, Joe made a mistake in his calculations by multiplying 28 quarts by 4 instead of dividing 28 quart by 4.

Reason:

Point C is located at (3,3)

Triple each coordinate since the scale factor is 3. That's how we go from (3,3) to (9,9)

If the scale factor was 5 for instance, then we'd go from (3,3) to (15,15)

This trick works only if the center of dilation is the origin.

Answer:

C' = (-3, 4)

Step-by-step explanation:

When a shape is dilated by a factor of 3, the size of the shape is multiplied by 3 in both the x and y directions. To find the new coordinates of point C' after a dilation by a factor of 3, we can multiply the original coordinates of point C by 3.

The original coordinates of point C are (-2, -10). When we multiply these coordinates by 3, we get (-6, -30) for the new coordinates of C' after the dilation. So the answer is (-6, -30)

What is cylinder?

Two parallel, identical bases connected by a curving surface form a 3D solid shape known as a cylinder. Similar to a disc in shape, these bases. The axis of the cylinder shape is a line drawn through the middle of, or connecting, two circular bases. Perpendicular distance is the measurement separating the two bases, and it is denoted by the letter "h," which stands for height. The distance between the two circular bases' centers and outer edges is known as the cylinder's radius and is denoted by the letter "r". A rectangle and two circles combine to form the cylinder.

A cylinder with base radius of 4 cm and a height of 7 cm is removed from the cuboid.

Volume of cuboid is = 16*15*24 = 5760 cm³

Volume of the cylinder = π r² h = π* 4² *7 = 351.85 cm³

So the surface area of the cylinder = 2π r h = 2*π*4*7 = 175.9 cm²

Total area of the cuboid = 2(240+360+384) = 1968

Toatl area = 1968+175.9 = 2143.9cm²

So the total area will be covered in the paint will be 2143.9cm²

a) To evaluate loga 15, we can use the property of logarithms that states logab = loga + logb. Since 15 = 3 * 5, we can use this property to find that loga 15 = loga 3 + loga 5. Since loga 3 = 0.56 and loga 5 = 0.83, we can add these values to find that loga 15 = 0.56 + 0.83 = 1.39.

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to express enormous numbers is this manner.

Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.

b) To evaluate loga(2/5), we can use the property of logarithms that states log(a/b) = loga - logb. Since 2/5 = 2*(1/5) we can use this property to find that loga(2/5) = loga2 - loga(1/5). Since loga2 = 0.36 and loga(1/5) = -loga5, we can subtract these values to find that loga(2/5) = 0.36 - 0.83 = -0.47

c) To evaluate loga (8a^4), we can use the property of logarithms that states log (a^n) = nloga. We get, loga (8a^4)=loga 8 + log (a^4)

=> loga 8 + loga (a^4)

The value of dy when x changes from -1 to -1.1 for equation y = 4x² is 0.84.

Here we are given an equation y = 4x²

In an equation, dy/dx, implies the change in y due to a change in x.

Now here we already have given that x changes from -1 to -1.1.

Hence, here we need to find the values of y when x = -1 and when x = -1.1

Then we need to subtract the value of y when x = -1.1 and when x = -1

We are given y = 4x²

Hence when x = -1,

y = 4 X 1

= 4

When x = -1.1

y = 4 X 1.21

Answer:

  a)  93 cm²

  b)  98 cm²

Step-by-step explanation:

You want the areas of the squares shown in each of the figures.

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides of a right triangle.

The square of the hypotenuse is 17² = 289.

The sum of the squares of the other two sides is ...

  shaded square + (14)² = 17²

  shaded square + 196 = 289

  shaded square = 289 -196 = 93 . . . . cm²

Sabcd = 93 cm².

The square of the diagonal is the sum of the squares of the sides. Each of those squares is the area of interest:

  14² = (shaded square) + (shaded square)

  196 = 2(shaded square)

  98 = shaded square

Sabcd = 98 cm².

Brooke's yard is a square with a side length of 22 meters.

Perimeter is the total distance around the outside edge of a two-dimensional shape. Perimeter is a measure of the length of the boundary of a shape and is typically expressed in units of length, such as feet or meters. Calculating the perimeter of a shape can help you measure the size of a yard, garden, or other outdoor area.

Since the perimeter of the part covered in gravel is 22 meters, we can use the formula for the perimeter of a square (4s) to find the length of one side of the square. Therefore, the side length of the part covered in grass is 4s = 22, or s = 5.5 meters.

Using the formula for the area of a square (A = s²), we can calculate the area of the grass section of Brooke's yard. The area of the grass section of Brooke's yard is A = s²= 5.5²= 30.25 square meters.
