Answer 1

Answer:

1.63

Step-by-step explanation:

-31 + 7 = -24

[tex]\sqrt{-24}[/tex]  = 4.9

4.9/3 = 1.63 (rounded down from 1.6333333)

Answer 2

Answer:

[tex]x = 2 \sqrt{2} i \: or \: x = - 2 \sqrt{2} i[/tex]

Step-by-step explanation:

• Add 7 to both sides.

[tex]3x {}^{2} - 7 + 7 = - 31 + 7[/tex]

Simplify

[tex]3x {}^{2} = - 24[/tex]

Divide both sides by 3

[tex] \frac{3x {}^{2} }{3} = \frac{ - 24}{3} [/tex]

Simplify

[tex]x {}^{2} = - 8[/tex]

Find the solution

[tex]x = \sqrt{ - 8} \: and \: x = - \sqrt{ - 8} [/tex]

Simplify

[tex] \sqrt{ - 8} = 2 \sqrt{2i} [/tex]

[tex] - \sqrt{ - 8} = - 2 \sqrt{2i} [/tex]

ANSWER:

[tex]x = 2 \sqrt{2} i \: and \: x = - 2 \sqrt{2} i[/tex]

Enter the first 4 terms of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.

f(n)=n3-7

The first 4 terms of the sequence are______,______,______,_______.​

Answers

Given:

The given rule is

[tex]f(n)=n^3-7[/tex]

Domain of the function is the set of whole numbers greater than 0.

To find:

The first 4 terms of the sequence.

Solution:

We have,

[tex]f(n)=n^3-7[/tex]

Domain of the function is the set of whole numbers greater than 0. So, the domain for first four terms of the sequence are 1, 2, 3 and 4 respectively.

For n=1,

[tex]f(1)=(1)^3-7[/tex]

[tex]f(1)=1-7[/tex]

[tex]f(1)=-6[/tex]

For n=2,

[tex]f(2)=(2)^3-7[/tex]

[tex]f(2)=8-7[/tex]

[tex]f(2)=1[/tex]

For n=3,

[tex]f(3)=(3)^3-7[/tex]

[tex]f(3)=27-7[/tex]

[tex]f(3)=20[/tex]

For n=4,

[tex]f(4)=(4)^3-7[/tex]

[tex]f(4)=64-7[/tex]

[tex]f(4)=57[/tex]

Therefore, the first 4 terms of the sequence are -6, 1, 20, 57 respectively.

Answer:

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

Step-by-step explanation:

Let the width of the rectangular lot be x meters.

So, Length of the same = 2x metres.

[tex]A(rectangular \:lot) = (2x)(x)[/tex]

[tex]\implies A(rectangular \:lot) = 2x^2[/tex]

When length is increasEd by 40 m and width by 6 m. Then....

New length = [tex](2x + 40) \:m[/tex]

New width =[tex](x + 6) \:m[/tex]

According to the question:

[tex](2x + 40)(x + 6) = 2(2x^2)[/tex]

[tex]\implies 2x(x + 6) + 40(x + 6) - 4x^2=0[/tex]

[tex]\implies 2x^2+12x + 40x + 240 - 4x^2=0[/tex]

[tex]\implies 2x^2- 4x^2+12x + 40x + 240 =0[/tex]

[tex]\implies -2x^2+52x + 240 =0[/tex]

[tex]\implies 2(x^2-26x - 120) =0[/tex]

[tex]\implies x^2-26x - 120=0[/tex]

[tex]\implies x^2-30x+4x - 120=0[/tex]

[tex]\implies x(x-30)+4(x - 30)=0[/tex]

[tex]\implies (x-30)(x+4)=0[/tex]

[tex]\implies x-30=0,\: x+4=0[/tex]

[tex]\implies x=30,\: x=-4[/tex]

Since, x represents the side length, so its value can't be negative.

[tex]\implies x=30[/tex]

[tex]\implies 2x=2(30)=60[/tex]

Thus,

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

2/3 of a hippos life is spent underwater, the rest of their life out of water is separated into grazing, sleeping and socialising in the ratio 4:7:1. The average life of a hippo is 45 years, how long will it spend doing each of these activities?

Answers

Answer:

Under water is 2/3×45= 30yrs

So rest is 1/3

1/3 is divide in 12 parts

1/3÷12=1/36

Grazing is 4/36×45= 5yrs

Sleeping is 7/36×45=8.75yrs

Socialising is 1/36×45=1.25yrs

Select each correct answer. A. 4 units B. 5 units C. 6 units D. 7 units E. 8 units F. 9 units. help, please!.

When given vertices for a geometric shapes we find the lengths of the side by using the formula:

When(x1, y1) and (x2, y2)

= √(x2 - x1)² + (y2 - y1)²

A= (−6, 5),B = (2, 5), C = (2, –1), and D = (–6, –1).

For AB

A= (−6, 5),B = (2, 5),

= √(2 -(-6)² + (5 - 5)²

= √8² + 0

= √64

= 8 units

For BC

B = (2, 5), C = (2, –1),.

√(2 - 2)² +(-1 - 5)²

= √0 + -6²

= √36

= 6 units

For CD

C = (2, –1), and D = (–6, –1).

= √(-6 -2)² + (-1 -(-1))²

= √-8² + 0²

= √64

= 8 units

For AD

A= (−6, 5), D = (–6, –1).

= √(-6 -(-6))² + (-1 - 5)²

= √0² + -6²

= √36

= 6 units

Therefore, the following numbers that are dimensions of the rectangle is

C) 6 units

E) 8 units

Jack draws a pattern of 2 cm wide strips on the wall in the following order: a red strip, a blue strip, an orange strip, a pink strip, and then he repeats the colors in the same order. How long is Jack's pattern if the first and last stripes he painted were red, and he painted six red strips in total?

Answers

Answer:

His pattern is 42cm long.

Step-by-step explanation:

Each repetition of the pattern is 8 cm (4 colors time 2cm each)

If the last color is red and he painted 6 red strips in total, then he repeated the pattern 5 times and ended on an extra red strip.

So 8cm times 5 repetitions equals 40, plus 2cm for the extra red strip.

Answers

Find x-intercept

The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.

3x + y = 16

3x + 1(0) = 16

x1 = 5.333 y1 = 0

Find y-intercept

The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.

3x + y = 16

3(0) + y = 16

y2 = 16 x2 = 0

What is 7/8 divided by 6/8

Simplify your answer.

Answers

Hey there!

7/8÷6/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

7/8×8/6=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

7×8/8×6=56/48

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 56 and 48 using

GCF(56,48) = 8

56÷8/48÷8=76

The fraction

7/6

is the same as

7÷6

Convert to a mixed number using

long division for 7 ÷ 6 = 1R1, so

7/6= [tex]1 \frac{1}{6} [/tex]

Therefore:

7/8÷6/8= 1 1/6

Let's do

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\div \dfrac{6}{8}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{8}{6}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{4}{3}[/tex]

The probability of an event describes the likelihood an event will occur. The likelihood of an event ranges from impossible to certain, but more common descriptions are likely to unlikely. An event is a single outcome or a group of outcomes. An outcome is a possible result of an action. Probability can be represented as a fraction, as a decimal, or as a percent. Something is fair if there is an equal chance for each outcome to occur.

16 - 2t = 3/2 t + 9 .

Answers

Answer:

t=2

Step-by-step explanation:

Start by subtracting 9 from both sides. You'll get 7-2t=3/2t. I made 3/2 a mixed number, so 1 1/2. You should have 7-2t=1 1/2t. Add 2t to both sides, because the 2t is negative. You should have 7=3 1/2t. Last step is to divide     3 1/2 into both sides. 7 divided by 3 1/2 is equal to 2, so t=2
