Answer:

i am not sure of my answer sorry can you make the question simpler maybe then I can answer it

Step-by-step explanation:

Answer: B and C

Step-by-step explanation: To start off, you subtract 3 from both sides, to get 4<z/2, then multiply both sides by 2, you get z>8. Now it's greater than 8, so it can't equal 8, so the answers would be B and C, since they are both greater than 8, and you have to select multiple choices.

Answer:

Square root2 /3

Step-by-step explanation:

1. Multiply both numerator and denominator by square root of 2.

2. Square root 2 times itself is just 2 that so denominator is 5-2

3. 1 times Square root 2 is just Square root 2. So numerator is Square root 2

4. 5-2=3 so final answer is Square root 2 over 3

Answer:

yes

Step-by-step explanation:

u={1,2,3,4,5,6,7,8,9}

m={2,4,6,8}

N={1,2,4,8}

O={2,4,6,8}

Now

M intersection (N intersection O) = (M intersection N) intersection O

or , {2,4,6,8} intersection {2,4,8} ={2,4,8}

intersection {2,4,6,8 }

:. {2,4,8} ={2,4,8}

Answer:

Step-by-step explanation:

⇒o 2/-3  Doesn't matter where the minus is as long as there an odd numbere of them.

o -3/-2

o -2/-3

⇒o - 2/3   This is given. Is it really listed.

o -3/2

o -2/2

There really are only 2 of them. 3/2 in any form is not equal to 2/3.

-2/2 = - 1 not -2/3

-2/-3 There are an even number of - signs. The answer is 2/3

Step-by-step explanation:

Answer:

i didthe math, its c

Answer:

14 degrees.

Step-by-step explanation:

I am assuming that the 56 degree angle is at the centre of the circle.

The angle at the top in the circle = 1/2 * 56 = 28 degrees.

The reflex angle = 360 - 56 = 304 degrees.

If we draw a line from the vertex of the 56 degrees angle to the vertex of 28 degree angle we bisect the reflex angle and the 28  degree angle. Also the 2  triangles formed are congruent ( by SSS).

So x = 180 - 1/2 * 28 - 1/2 * 304

= 180 - 14 - 152

= 180 - 166

= 14 degrees.

Answer:

I believe it is D

Step-by-step explanation:

Answer: 26

Step-by-step explanation:

Okay, so... The new equation would be -2(-3)+20...

So follow the rule of PEMDAS, PEMDAS is;

Parentheses

Exponents

Multiplication

Division

Adding

and Subtracting

Since there are no equations in parentheses and no exponents, we start with multiplication. Which would be -2(-3). ANY parenthesized number beside another number means you must multiply them.

-2(-3) = 6 because a negative multiplied by a negative is a positive..

Now we have 6 + 20 which is 26, so 26 is your answer.

Answer:

The remainder is: f(-1) = -4

Step-by-step explanation:

We know that when a polynomial function f(x) is divided by x-c, then the remainder is f(c)

Given the function

[tex]f\left(x\right)\:=\:x^4\:-\:5[/tex]

It is stated that the function f(x) is divided by x + 1.

Thus, substituting x = -1 in the function to find the remainder f(-1)

i.e

f(-1) = (-1)⁴ - 5

f(-1) = 1 - 5

f(-1) = -4

Therefore,

The remainder is: f(-1) = -4

Answer:

9

Step-by-step explanation:

Answer:

A. Yes; acute triangle

Step-by-step explanation:

a=6

b=14

c=13

Using Pythagorean theorem-

c^2 = a^2 + b^2

13^2 = 6^2 + 14^2

169 = 36 + 196

169 = 232

169 < 232

Therefore, (a) the triangle is acute.

If 169 =169 there would be a right triangle.

If c were greater than a + b there would be an obtuse triangle.

Answer:

1 mile

Step-by-step explanation:

Step one:

given

total distance = 15miles

Jack walks at a pace of 1.5 miles per hour

after 4 hours he will cover a distance of

1.5*4= 6 miles

Jill walks at a pace of 2 miles per hour

after 4 hours he will cover a distance of

2*4= 8 miles

Step two:

The total distance jack and jill must have covered after 4 hours is

8+6= 14 miles

the distance apart will be 15-14= 1 mile

Answer:

The required equation is: [tex]\mathbf{f(x)=\frac{3}{4}x-\frac{29}{4}}[/tex]

Step-by-step explanation:

We need to find equation from the table given

x     f(x)

3     -5

7     -2

11     1

15    4

We can write equation in the form of [tex]y=mx+b[/tex]

where m is slope and b is y-intercept.

Finding Slope

We can used the slope formula to find slope: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table we have: [tex]x_1=3, y_1=-5, x_2=7, y_2=-2[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-(-5)}{7-3} \\Slope=\frac{-2+5}{7-3}\\Slope=\frac{3}{4}[/tex]

So, we get slope [tex]m=\frac{3}{4}[/tex]

Now, finding y-intercept

Using the slope [tex]m=\frac{3}{4}[/tex] and point (3,-5) we can find y-intercept

[tex]y=mx+b\\-5=\frac{3}{4}(3)+b\\-5=\frac{9}{4}+b\\b=-5-\frac{9}{4}\\b=\frac{-5*4-9}{4}\\b=\frac{-20-9}{4}\\b=\frac{-29}{4}[/tex]

The y-intercept is [tex]b=\frac{-29}{4}[/tex]

So, the equation having slope [tex]m=\frac{3}{4}[/tex] and y-intercept [tex]b=\frac{-29}{4}[/tex] will be:

[tex]y=mx+b\\y=\frac{3}{4}x-\frac{29}{4}[/tex]

The required equation is: [tex]\mathbf{f(x)=\frac{3}{4}x-\frac{29}{4}}[/tex]

Answer:

Growth rate is -0.25

Growth factor is 0.75

Step-by-step explanation:

The general form of an exponential equation is;

y = a(1 + r)^x

Where a is the initial value

r is the growth rate

For x = 3; we have

168.75 = 400(1 + r)^3 •••• (i)

For x = 2, we have

225 = 400(1 + r)^2 •••••(ii)

Divide i by ii

That will be;

168.75/225 = 1 + r

1 + r = 0.75

r = 0.75-1

r = -0.25

The growth rate is -0.25

The growth factor is 1-0.25 = 0.75

Answer:

- high tide occurs at 12 noon and 12 midnight

- Low tide occurs at 6 a.m and 6 p.m

- maximum depth value = 20 ft

- Minimum depth value = 15 ft

Step-by-step explanation:

The depth is modelled as;

y = 20 + 5 cos (πt/6)

We are told that t = 0 represents 12:00 midnight.

This is high tide because at t = 0, the cos function will be at it's maximum value of 1 since cos 0 = 1.

Max depth value is;

y = 20 + 5(0)

y = 20 ft

Minimum depth value will be the low tide and it will be when the cos function is equal to -1.

Thus;

y = 20 + 5(-1)

y = 15 ft

Since t represents number of hours and since at 12 midnight, t = 0, thus; high tide will occur again at;

12 noon

Also, let's check for low tide.

Let's try t = 6 which means 6 a.m

Thus;

y = 20 + 5 cos (π(6)/6)

y = 20 + 5 cos π

Cos π has a value of -1

Thus;

y = 20 + 5(-1)

y = 20 - 5

y = 15 ft

Thus;

Low tide occurs at 6 a.m and 6 p.m

Answer:35

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

-42=-7+5x

-42 + 7 = 5x

5x = - 35

x = -35/5

x = - 7

Hope it helps!

Answer:

x = -7

Step-by-step explanation:

Given equation:

[tex]-42 = -7 + 5x[/tex]

        [tex]-42 = 5x -7[/tex]

    2. Flip the equation.

        [tex]5x + 7 = -42[/tex]

    3. Add 7 to each side.

        [tex]5x - 7 + 7 = -42 + 7[/tex]

        [tex]5x = -35[/tex]

    4. Divide both sides by 5.

        [tex]\frac{5x}{5}[/tex] = [tex]\frac{-35}{5}[/tex]

    5. Divide the fraction.

        [tex]-35[/tex] ÷ [tex]5[/tex] = [tex]-7[/tex]
