Answer:

it is a 3:5

Step-by-step explanation:

Given:

The point is (-2,4).

To find:

Whether the point (-2,4) satisfy [tex]y<3x+5,y=3x+5[/tex] or [tex]y >3x+5[/tex].​

Solution:

We have a point (-2,4).

Substituting x=-2 in 3x+5 and check whether it is greater, equal or less than y value, i.e., 4.

[tex]3x+5=3(-2)+5[/tex]

[tex]=-6+5[/tex]

[tex]=-1[/tex]

-1 is less than 4.

[tex]3x+5<4[/tex]

[tex]3x+5<y[/tex]

In can be written as

[tex]y>3x+5[/tex]

Therefore, the given point (-2,4) satisfy [tex]y >3x+5[/tex].

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.

A camper attaches a rope from the top of her tent, 4 feet above the ground, to give it more support. If the rope is 8 feet long.

Then the length of the stake needs to be from the middle of her tent will be

We have

P = 4 ft

H = 8 ft

Then the base is given by the Pythagoras theorem.

B² = H² - P²

B² = 8² - 4²

B² = 64 - 16

B² = 48

B = 6.9 ft

ether 12 or 4 feet.

Step-by-step explanation:

The volume of the rectangular prism will increase by 33% if the width, length, and height are each increased by 10%.

Every three-dimensional object occupies some space. This space is measured in terms of its volume. Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

The formula for the volume of a rectangular prism is:

V = l x w x h

where

“l” is the base length

“w” is the base width

“h” is the height of the prism

If the width, length, and height are each increased by 10%, the equation will now become:

[tex]V_{2}= 1.10 l * 1.10 w*1.10h[/tex]

[tex]V_{2}= 1.331* l*w*h[/tex]            V = l*w*h

[tex]V_{2}= 1.331* V[/tex]

Hence, if the width, length, and height are each increased by 10%, the volume of the rectangular prism will increase by 33%.

Answer:

188.5

Step-by-step explanation:

in order to find the circumference you need to know the radius which is half of the diameter. the picture shows the formula used.

Answer:

The required polynomial is:

[tex]f\left(x\right)=x^3+8x^2+19x+12[/tex]

Step-by-step explanation:

Given the zeros

-4, -1, -3

Zeros can be written as:

x = -4, x = -1, x = -3

Finding the factors

x = -4

x +4 = 0

x = -1

x + 1 = 0

x = -3

x + 3 = 0

Thus, the factor are:

(x+4) (x+1) (x+3)

The original function can be computed by multiplying the factors

[tex]\left(x+4\right)\left(x+1\right)\left(x+3\right)=0[/tex]

as

[tex]\left(x+4\right)\left(x+1\right)=x^2+5x+4[/tex]

so the expression becomes

[tex]\left(x^2+5x+4\right)\left(x+3\right)=0[/tex]

Distribute parentheses

[tex]x^2x+x^2\cdot \:3+5xx+5x\cdot \:3+4x+4\cdot \:3=0[/tex]

[tex]x^2x+3x^2+5xx+5\cdot \:\:3x+4x+4\cdot \:\:3=0[/tex]

[tex]x^3+3x^2+5x^2+15x+4x+12=0[/tex]

Add similar elements: [tex]3x^2+5x^2=8x^2[/tex]

[tex]x^3+8x^2+15x+4x+12 = 0[/tex]

Add similar elements: [tex]15x+4x=19x[/tex]

[tex]x^3+8x^2+19x+12=0[/tex]

Thus, the required polynomial is:

[tex]f\left(x\right)=x^3+8x^2+19x+12[/tex]

Answer: 1 and 3 dont 2 and 4 do have a line of symmetry

Step-by-step explanation:

Graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.  

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The line of symmetry is an imaginary line that runs through the centre of a line or shape creating two perfectly halves.

To check a function to be symmetrical about the origin we need to replace y with minus y and x with minus x and the function must be equal to original function.

In the given graphs, 1 and 3 are not symmetrical and 2 and 4 are symmetrical.

Hence graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.

Answer:

e= 2

W= 15

m= 9

Step-by-step explanation:

for e: yout multiply 5 x 7 to get 35 so 2 x 7 = 14

for W: 20/10 = 2 so divide 30/2 to get 15

for m: 11 x 2 = 22 so do 18 divided 2 to get 9

Answer:

E = 2

W = 15

M = 9

Step-by-step explanation:

You just have to make the denominator / numerator the same.

[tex]\frac{E}{5}[/tex] = [tex]\frac{14}{35}[/tex]

Multiply the first fraction by 7 so that their denominators are both 35.

[tex]\frac{7E}{35}[/tex] = [tex]\frac{14}{35}[/tex]

7E = 14

E = 14 ÷ 7

E = 2

[tex]\frac{20}{30}[/tex] = [tex]\frac{10}{W}[/tex]

Multiply the second fraction by 2 so that their numerators are both 20.

[tex]\frac{20}{30}[/tex] = [tex]\frac{20}{2W}[/tex]

2W = 30

W = 30 ÷ 2

W = 15

[tex]\frac{M}{11}[/tex] = [tex]\frac{18}{22}[/tex]

Multiply the first fraction by 2 so that their denominators are both 22.

[tex]\frac{2M}{22}[/tex] = [tex]\frac{18}{22}[/tex]

2M = 18

M = 18 ÷ 2

M = 9

Answer:

Negative

Step-by-step explanation:

When an even number of negatives are multiplied together, the product will be positive (because two negatives cancel out). When an odd number of negatives are multiplied together, the product will be negative.

In the given expression, there is also a singular (1) at the end, which we can ignore since anything multiplied by 1 is itself. The other numbers are all negative and there are 3 of them, and since 3 is an odd number, the product will be negative.

We need to know about the relation between roots of a quadratic equation for solving the question. The quadratic equation with roots 3/4 and 1/2 is [tex]8x^{2} -10x+3=0[/tex]

Quadratic equation is an equation with the highest order of variable being 2. Roots of a quadratic equation are the values that satisfy the equation.Since quadratic equation has the highest order as 2, the equation has two roots. Roots of a quadratic equation can be real and unique, real and equal or imaginary. The roots of a quadratic equation can be used to get the quadratic equation itself.

Let there be a quadratic equation:

[tex]ax^{2} +bx+c=0\\x^{2} +\frac{b}{a} x+\frac{c}{a} =0[/tex]

Let the roots of the quadratic equation be α and β, then

α+β=-b/a

αβ=c/a

In this question we know the two roots are 3/4 and 1/2. So we can derive the quadratic equation from them

[tex]\frac{3}{4} +\frac{1}{2} =\frac{-b}{a} \\\frac{-b}{a} =\frac{5}{4}[/tex]

[tex]\frac{3}{4}[/tex]×[tex]\frac{1}{2} =\frac{c}{a}[/tex]

[tex]\frac{c}{a} =\frac{3}{8}[/tex]

The quadratic equation is:

[tex]x^{2} -\frac{5}{4} x+\frac{3}{8} =0\\8x^{2} -10x+3=0[/tex]

Therefore we found the quadratic equation with roots 3/4 and 1/2 to be [tex]8x^{2} -10x+3=0[/tex]
