5x-8=  ...is eight less than five times another product

=85

So our equation is x·(5x-8)=85

Steps:

distribute x

5x^2-8x=85

Subtract 85 to create a quadratic equation

5x^2-8x-85=0

3x2-3x+9

Step-by-step explanation:

(h-k)(3)

(X2+1-(x-2))(3)

(x2+1-x+2)(3)

3x2+3-3x+6

3x2-3x+9

Hello,

h(x)=x²+1

k(x)=x-2

First of all, you must understand that:

(h+k)(x)=h(x)+k(x)

So, (h+k)(3)=h(3)+k(3)=(3²+1)+(3-2)=(9+1)+1=11

3h(2)+2k(3)=3*(2²+1)+2*(3-2)

=3*(4+1)+2*1

=15+2

=17

Answer:

The signal would have experienced aliasing.

Step-by-step explanation:

Given that:

the bandwidth of the signal [tex]f_m[/tex] = 36MHz

= 36 × 10⁶ Hz

The sampling frequency [tex]f_s[/tex] = 36 × 10⁶ Hz

Suppose the sampling frequency is equivalent to the bandwidth of the signal, then aliasing will occur.

Therefore, according to the Nyquist criteria;

Nyquist criteria posit that if the sampling frequency is more above twice the maximum frequency to be sampled, a repeating waveform can be accurately reconstructed.

∴

By Nyquist criteria, for perfect reconstruction of an original signal, i.e. the received signal without aliasing effect;

Then,

[tex]f_s \geq 2f_m[/tex]

∴

The signal would have experienced aliasing.

Answer:

Step-by-step explanation:

[tex]sin(2\theta)=2sin\theta~cos\theta\\\\cos(2\theta)=cos^2\theta-sin^2\theta\\\\cos\theta=\frac{24}{25}\\\\sin^2\theta+cos^2\theta=1~=>sin\theta=\pm\sqrt{1-cos^2\theta}\\\\we ~will~ use~ the ~minus~ sign~because~sin\theta~is~negative~in~IV~cuadrant\\sin\theta=-\sqrt{1-{(\frac{24}{25})}^2}=-\frac{7}{25}[/tex]

Now we cal calculate the quantities requested

[tex]sin(2\theta)=2sin\theta cos\theta=2(-\frac{7}{25})\frac{24}{25}=-\frac{336}{625}\\\\[/tex]

[tex]cos(2\theta)=cos^2\theta-sin^2\theta=(\frac{24}{25})^2-(-\frac{7}{25})^2=\frac{527}{625}[/tex]

[tex]tan(2\theta)=\frac{sin(2\theta)}{cos(2\theta)}=\frac{-\frac{336}{625}}{\frac{527}{625}}=-\frac{336}{527}[/tex]

Answer:

[tex]Height = 173.8ft[/tex]

Step-by-step explanation:

Given

[tex]\theta = 40^o[/tex]

[tex]d = 200ft[/tex] --- distance from building

[tex]h=6ft[/tex]--- height of the building

Let the height of the building be H. So:

[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

[tex]\tan(40) = \frac{H}{200}[/tex]

Make H the subject

[tex]H = 200 * \tan(40)[/tex]

[tex]H = 167.82[/tex]

The required height s:

[tex]Height = H + h[/tex]

[tex]Height = 167.82 + 6[/tex]

[tex]Height = 173.82ft[/tex]

[tex]Height = 173.8ft[/tex] --- approximately

Cora, her sister, and four friends. So there are 6 people, 120 candies are divided equally in the bag, so each person gets 20 candies

Each person will get 20 candles.

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now it is given that,

Number of candles in the bag = 120

Cora, her sister, and four friends are going to share.

So, Number of person = 6

Thus, candles each person gets = Number of candles in the bag / Number of person

⇒ candles each person gets = 120 / 6

⇒ candles each person gets = 20

Thus, each person will get 20 candles.

Answer:

Step-by-step explanation:

Answer:

Since R32,210 is greater than R30,000; it simply means that Mr X would get greater return on investment

Step-by-step explanation:

a) Mr X Return

We have the compound interest formula as;

V = P(1 + r)^t

V is the value yielded after some certain amount t

Where P is the amount invested = R20,000

r is the yearly interest rate = 10/100 = 0.1

t = 5 years

so we have;

V = 20,000(1 + 0.1)^5 = R32,210.2

b) Mrs X return

We use the simple interest formula here;

A = P + I

I = PRT/100

where P, the principal is the amount invested = R20,000

R = 10%

T = 5 years

I = (20,000 * 10 * 5)/100

I = R10,000

A = R20,000 + R10,000

A = R30,000

Since R32,210 is greater than R30,000; it simply means that Mr X would get greater return on investment

Answer:

[tex]Time = 560\ mins[/tex]

Step-by-step explanation:

Given

[tex]Candles = 2[/tex] --- candles melted

[tex]Divisions = 12[/tex]

[tex]Time = 4\ hrs[/tex] --- time to melt

Required

The time since the first was lit

If 1 candle melts in 4 hours, 2 candles will melt in 8 hours.

i.e.

[tex]x = Candles * Time[/tex]

[tex]x = 2 * 4hrs[/tex]

[tex]x = 8hrs[/tex]

For the 3rd candle that has melted, 4 inches

First, calculate the fraction that melt

[tex]Fraction = \frac{Melt}{Division}[/tex]

[tex]Fraction = \frac{4}{12}[/tex]

[tex]Fraction = \frac{1}{3}[/tex]

The time to melt is:

[tex]y = Fraction * Time[/tex]

[tex]y= 4 * \frac{1}{3}[/tex]

[tex]y= \frac{4}{3}hrs[/tex]

So, the required time is:

[tex]Time = x + y[/tex]

[tex]Time = 8hrs + \frac{4}{3}hrs[/tex]

Convert to minutes

[tex]Time = 8*60mins + \frac{4}{3}*60mins[/tex]

[tex]Time = 480mins + 80mins[/tex]

[tex]Time = 560\ mins[/tex]

Answer:

x = 45/8

Step-by-step explanation:

8x – 3y = 36

Let y=3

8x – 3*3 = 36

8x - 9 = 36

Add 9 to each side

8x -9+9 = 36+9

8x = 45

Divide each side by 8

8x/8 = 45/8

x = 45/8

Answer:

x = 45 / 8

Step-by-step explanation:

8 x - 3 y = 36

8 x - 3 × 3 = 36 ( given :- y = 3 )

8 x - 9 = 36

add 9 to both side

8 x - 9 + 9 = 36 + 9

8 x = 45

Divide each side by 8

8 x / 8 = 45 / 8

X = 45 / 8

Answer:

- 31

Step-by-step explanation:

4(3 − 2) − 7(5)

Subtract 3 - 2

4(1) - 7(5)

Multiple -7 and 5

4 - 35

Subtract 4 - 35

The correct answer is -31.

The simplified form of 4(3 − 2) − 7( + 5) is -31.

To simplify the given expression, using (PEMDAS/BODMAS) and simplify each part step by step.

4(3 − 2) − 7( + 5)

First, simplify the expressions inside the parentheses:

3 − 2 = 1

+ 5 = 5

then, the expression becomes:

4(1) − 7(5)

Next, let's perform the multiplications:

4(1) = 4

7(5) = 35

The expression now becomes:

4 − 35

Finally, let's perform the subtraction:

4 − 35 = -31

Therefore, the simplified form of 4(3 − 2) − 7( + 5) is -31.

Answer:

  1328.4 square units

Step-by-step explanation:

The total surface area is the sum of the areas of the trapezoidal bases, and the areas of each of the four rectangular faces.

The area of each trapezoidal base is ...

  A = 1/2(b1 +b2)h

  A = 1/2(10 +24)(9) = 153 . . . . square units

__

The total area of the four rectangular faces is ...

  A = bh . . . . area of one face

  A = 11.4(18) +10(18) +11.4(18) +24(18) = (11.4 +10 +11.4 +24)(18) = 1022.4

Step-by-step explanation:

hope you understand

Answer:

The ratios of 3:2, 6:4, and 9:6 are all equivalent because when you divide the numerator over the denominator, you get the same result for all of them. This means that if we took 3/2 and got 1.5, and took 6/4 and got 1.5 as an answer, and took 9/6 and got 1.5 as an answer as well, we would have the same answer for all of them. This is why (in my own words) the ratios are all equivalent.
