A research submarine dives at a speed of 100 ft/min directly toward the research lab. How
long will it take the submarine to reach the lab from the surface of the ocean?
It will take minutes for the submarine to reach the lab from the surface of the ocean
(Round to one decimal place as needed.)

Answer:

It depends on what the question is.

Step-by-step explanation:

X= (any number that isn't 0)

so X=1 X=2 x=3 those would all work

the x intercept is when any point on the x axis is intercepted, and any line with a slope that isn't 0 will always intersect that point. So you need to have X= something so that it will stay parallel to the X axis, but never intersect.

The ball is hits the ground after 3.4 seconds it strike s

From the question, we have the following parameters that can be used in our computation:

h(t)=-18t^2+60t+4.

Rewrite as

h(t) = -18t² + 60t + 4

When the ball hits the ground, we have

h(t) = 0

So, the equation becomes

-18t² + 60t + 4 = 0

Divide through by 2

-9t² + 30t + 2 = 0

So, we have

9t² - 30t - 2 = 0

Using a graphing tool, we have

t = 3.4

Hence, the time is 3.4 seconds

Step-by-step explanation:

∠ABP = ∠CBP (By angle bisector).∠PXB = ∠PYB (All right angles are congruent).BP = BP (Common side).ΔBXP = ΔBYP (By ASA rule).PX = PY (corresponding sides of congruent triangles are the same).

If two figures are exactly the same in sense of their length side all things then they will be congruent.

In other meaning, if you can copy a figure then that copy and the original figure will be congruent.

As per the given two bisectors' angle.

∠ABP = ∠CBP (By angle bisector)

∠PXB = ∠PYB (All right angles are congruent).

BP = BP (Common side)

ΔBXP = ΔBYP (By ASA rule)

PX = PY (corresponding sides of congruent triangles are the same)

Hence "∠ABP Equals ∠CBP (By angle bisector). ∠PXB = ∠PYB (All right angles are congruent). BP = BP (Common side) (Common side). ΔBXP = ΔBYP (By ASA rule). PX = PY (matching sides of congruent triangles are the same) (corresponding sides of congruent triangles are the same).".

Answer:

Rhombus

Step-by-step explanation:

A rhombus is a type of quadrilateral in which all four sides are of equal length. Also, the diagonals are perpendicular to one another and bisect each other too.

Figure PQRS may be mapped onto image P'Q'R'S using only one transformation, which is a reflection.

There are four different ways to change a point, line, or geometric figure, and each one has an impact on the object's shape and/or placement. Pre-Image is the shape of the item before transformation, and image is the position and final shape of the object after transformation.

As a result, the coordinates for the figure PQRS are P(2,2) Q(5,2) R(5,6) and S(2,6), whereas those for the picture P'Q'R'S' are P(-6,2) Q(3,2) R(3,6) and S' (-6,6).

Reflection is a sort of transformation that flips a shape along a mirror line, also known as a line of reflection, such that each point is at the same distance from the mirror line as its mirrored point.

The y-axis reflects the PQRS figure, which is then translated left to 1 unit.

As a result, one transformation can reflect picture P'Q'R'S onto figure PQRS.

The value of the steep slopes or the direction of a line in a coordinate plane is known to as the slope of a line, also known as the gradient.

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. Mostly on y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

There are 2 perfect squares that are two-digit and divisible by 3.

To find the two-digit perfect squares that are divisible by 3, we can start by finding all the two-digit perfect squares and then check which ones are divisible by 3. The two-digit perfect squares are:

4: 16

5: 25

6: 36

7: 49

8: 64

9: 81

Now we can check which of these numbers are divisible by 3:

16: not divisible

25: not divisible

36: divisible

49: not divisible

64: not divisible

81: divisible

Thus, there are two two-digit perfect squares that are divisible by 3: 36 and 81.

The number of roots of a polynomial is always less than or equal to the degree of the polynomial because the degree of f(x) is the sum of the degrees of the factors

The number of roots of a polynomial is equal to the number of values of x that make the polynomial equal to zero.

The degree of a polynomial is the highest exponent of the variable in the polynomial. For example, the polynomial x² + 3x + 2 has a degree of 2, because the highest exponent of x is 2.

It can be shown mathematically that the number of roots of a polynomial is always less than or equal to the degree of the polynomial. This is known as the Fundamental Theorem of Algebra.

Since each of the factors has a degree of 1, the degree of f(x) is the sum of the degrees of the factors, which is equal to 3.

Therefore, the number of roots of a polynomial is always less than or equal to the degree of the polynomial.

Answer:

To determine Beau's front-end ratio, you need to calculate the percentage of his monthly income that will be taken up by his mortgage, homeowner's insurance, property taxes, credit card payment, and car payment.

First, add up all of Beau's monthly expenses: $1,025 (mortgage) + $635 (homeowner's insurance) / 6 (months in a half year) + $4,785 (property taxes) / 12 (months in a year) + $2,000 (credit card payment) + $250 (car payment) = $3,715.83.

Next, divide this total by Beau's monthly income: $3,715.83 / ($89,750 / 12) = $3,715.83 / $7,479.17 = 0.49, or approximately 49%.

Since this ratio is expressed as a percentage, the final answer is 49%. Therefore, the correct answer is (d) 24%.

The equation of a line that is parallel to y= 1/2 − 5 and passes through the point (-4, 1) will be y = (1/2)x + 3.

Two figures are similar by transformations if they have the same shape, but are either rotated, reflected, translated, or enlarged/reduced. They must also have corresponding angles of the same degree and corresponding sides of the same length (or in the case of enlargement/reduction, in the same ratio).

Four distinct approaches to modify the position and/or shape of a point, line, or geometric figure are collectively referred to as transformations. The Pre-Image of the object is its initial shape, while the Image, after transformation, is the final shape and location of the thing.

A drastic change in shape or appearance is called a transformation. An crucial occasion, such as receiving your driver's license, enrolling in college, or getting married, might change the course of your life. Extreme, dramatic change is what we refer to as transformation.

What are composite functions?

A composite function is generally a function that is written inside another function. The composition of a function is done by substituting one function into another function. For example, f [g (x)] is the composite function of f (x) and g (x). The composite function f [g (x)] is read as “f of g of x”.'

Given:

                [tex]f(x)=4x^2-5x\\\\g(x)=3x^2+6x-4[/tex]

Now by using the definition of composite functions we can write,

      [tex](f-g)(x)=f(x)-g(x)\\\\(f-g)(x)=4x^2-5x-(3x^2+6x-4)\\\\(f-g)(x)=4x^2-5x-3x^2-6x+4\\\\(f-g)(x)=x^2-11x+4[/tex]

Additive inverse of 2 is -2.

Multiplicative Inverse of 2 is 1/2.

To produce a result equal to 0, add the original number and the additive inverse by simply reversing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.

A multiplicative inverse or reciprocal for a number x is a number that, when multiplied by x, produces the multiplicative identity, or 1. It is represented by 1/x or x/1. A fraction a/b has a multiplicative inverse of b/a. Divide 1 by the real number to obtain the multiplicative inverse of the number.
