Answer:
c. [-1, infinity)
Step-by-step explanation:
the domain the interval or set of valid x values (while the range is the same for the valid y values).
what is the smallest value of x we see for the graph ?
for x values we need to look left and right.
and the more left the value, the smaller it is.
so, in other words, what is the left-most x value e can find ?
x = -1
that is the "starting point" of the function. there is no functional value for any smaller x.
and then clearly, the function goes on and on to the right without any boundary in sight. so, it keeps going to the right in all eternity, that means it goes to infinity.
therefore the answer.
keep in mind that "infinity" is not a number, only a concept. so, when writing "infinity" at an interval end, it is not included (and we use a round bracket).

In the problem, the number is:
3.85663
I’ll tell you the places:
3 is the ones place. Then there’s the decimal, now we’re adding “th.” After the decimal is 8, the tenths place. After that is 5, the hundredths place. Then it’s 6, the thousandths place. Then another 6, ten thousandths place. And last, 3, the hundred thousandths place.
It’s just like the places you learned in elementary school, but backwards and with “th” added, also no “oneths place,” that just sounds weird.
And you should know how to round, but if you don’t, you simply just look at the next number after the number you’re rounding. If the number is greater than 5, round up, if less, round down. And 5 is rounded up in most cases. So here, the number after the hundredths place is 6, so we round the hundredths place up, 5 to 6.
A rectangle has a perimeter of 112. If the sides are 5x & 3x + 5, what is x and what are each of the sides?
Answers
The value of X is 7.625 while the two sides are 38.125 and 27.875.
To find the perimeter: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 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.
What is a linear factor of a polynomial?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.

A cylinder with base radius of 4 cm and a height of 7 cm is removed from the cuboid.
The remaining solid is to be painted on all its surfaces. Find the area that will be covered in paint.
Answers
the total area will be covered in the paint will be 2143.9cm²
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

Answers
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)

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)

a)The square of the hypotenuse is 17² = 289.

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

When x = -1.1
y = 4 X 1.21

The area of the irregular polygon is 24 square inches. Hence option A is the correct option.
What is an irregular polygon?
An irregular polygon does not have all of its sides equal, nor are all of its angles equal in size. Scalene triangles, right triangles, isosceles triangles, rectangles, parallelograms, irregular pentagons, irregular hexagons, and so on are examples of irregular polygons.
The length of DE is 5 in and HI is 5in.
The length of AL is 12in.
The length of AD + EH + IL = AL - (DE+HI) = 12 - (5+5) = 2 in
The length of AB = DC = EF = HG = IJ = LK = 7in.
The sum area of the rectangles ABCD, EFGH, and IJKL is
AB×AD + EF×EH + IJ×IL
= 7×AD + 7×EH +7×IL
= 7(AD + EH + IL)
= 7×2
= 14 square inches
The length of DW = EX = HY = IZ = 7 - 6 = 1in.
The area of DWXE is DW×WX = 1×5 = 5 square inches

The coefficient ratio of the words

The fact that 4x²≥0 for x ∈ R means that

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