Identify the ‘false’ statement.
a) (-317) < 603
b) (-333) < (-777)
c) 630 > 234
d) 1250 > (-750)

Answers

Answer:

the false statement would be option b) (-333) < (-777).

Step-by-step explanation:

in negative numbers, the smallest negative number would be considered larger when compared to a large negative number. additionally, when you plot these numbers on a number line, it is evident that -333 would be closest to 0, and -777 would be the farthest. thus, -333 is larger than -777.

Through (4,-4) parallel to y=3

Answers

Answer:
y = -4

Explanation:
The graph of y = 3 is horizontal.

The slope must be 0 for a line to be horizontal, and thus parallel to y=3.

In slope-intercept form (y = mx + b), “m” is the slope, “b” is the y-intercept.
When the slope, m = 0, the equation becomes y = b.

Point (4,-4) is written (x, y).
y = -4

Since y = b, b = -4.

Therefore, the equation is y = -4.

Answer:

y = -4

Step-by-step explanation:

Because y = b, b = -4, the equation would be written as y = -4.

Calculate the distance between the points J=(4, -2) and E = (7. – 7) in the coordinate plane.
Give an exact answer (not a decimal approximation).

Answers

Answer:

Step-by-step explanation:

√[(7-4)^2+{-7-(-2))^2] = √36 = 6

The distance between the points J=(4, -2) and E = (7. – 7) in the coordinate plane is 6.

What is coordinate plane ?

"A coordinate plane is a two-dimensional plane formed by the intersection of two number lines. One of these number lines is a horizontal number line called the x-axis and the other number line is a vertical number line called the y-axis. These two number lines intersect each other perpendicularly and form the coordinate plane.

The plane is called two-dimensional because anywhere on this plane where you can put your finger, the location of that point will need two things– its distance on the x-axis and its distance on the y-axis."

Using the distance formula between the points

Given, J = (4,-2) and E = (7,-7)

Distance formula = [tex]\sqrt((x1 - x2)^2 -(y1 - y2)^2)[/tex]

[tex]= \sqrt((4-7)^2 + (-2 - (-7))^2)\\\\= \sqrt(9 + 25) = 6[/tex]

Hence, distance between the points J and E = 6

a wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. find the speed of the boat as she paddles the lake if the river current is 2 km/h. Pls answer. You'll get 100 points.

Answers

Answer:

5 km/h or 6 km/h

Step-by-step explanation:

Let the speed of the boat be xSpeed against the current in the river is x - 2

Time in the river:

6/(x - 2)

Time in the lake:

15/x

The difference:

6/(x - 2) = 15/x - 1

Solve for x to find the speed of the boat

Multiply both sides by x(x - 2) to clear the fraction:

6x = 15(x - 2) - x(x - 2)6x = 15x - 30 - x² + 2xx² - 11x + 30 = 0(x - 5)(x - 6) =0x -5 = 0, x - 6 = 0x = 5 km/h, x = 6 km/h

A wire is attached to the top of a tower and to a point on the ground that is 35 m from the base of the tower. If the wire makes a 65 degree angle with the ground, how long is the wire? Round your answer to the nearest tenth

Answers

Answer:

83 m

Step-by-step explanation:

The computation of the length of the wire is shown below:

Let us assume the length of the wire be x

Given that

There is 35m from the base of the tower

And, the angle with the ground is 65 degree

So, the length of the wire is

cos 65 = 35 ÷ x

x = 35 ÷ cos 65

= 83 m

What is the GCF of a¹²b⁴, a⁴b⁸, a²⁴b¹⁶ and a¹²b²⁰?​

Answers

Given:

a¹²b⁴, a⁴b⁸, a²⁴b¹⁶ and a¹²b²⁰.

To find:

The GCF of given terms.

Solution:

Greatest common factor (GCF): To find the GCF of two or more numbers, we need to find the product of their prime factor with their maximum powers.

The given terms are

[tex]a^{12}b^{4},a^{4}b^8, a^{24}b^{16}, a^{12}b^{20}[/tex]

Here, each term has two prime factors a and b. The highest power of a is 24 and the highest power of b is 20. So, the GCF of given terms is

[tex]GCF=a^{24}\times b^{20}[/tex]

[tex]GCF=a^{24}b^{20}[/tex]

Therefore, the GCF of a¹²b⁴, a⁴b⁸, a²⁴b¹⁶ and a¹²b²⁰ is a²⁴b²⁰.
