Answer:

The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]

Step-by-step explanation:

Cosine is is calculated as adjacent over hypotenuse.  The line adjacent to A  is 3 in length.

So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator

[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

Answer:

  y +2 = -1/2(x -7)

Step-by-step explanation:

The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...

  m = rise/run = 6/3 = 2

A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...

  -1/m = -1/2

We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

An equation for the desired line is ...

  y +2 = -1/2(x -7)

__

This can be rearranged to other forms.

  y = -1/2x +3/2 . . . . . slope-intercept form

  x +2y = 3 . . . . . . . . . standard form

Answer:

[tex]f(d) = 15 + 3d[/tex]

Step-by-step explanation:

Given

[tex]a = 15[/tex] --- day 1

[tex]Rate = 3[/tex] -- i.e. triples daily

Required

Determine the function f(d)

The number of customers on a particular day is:

Customers = Day 1 + Rate * Number of days

Represent as a function:

[tex]f(d) = a + Rate* d[/tex]

Where d is the number of days.

So, we have:

[tex]f(d) = 15 + 3* d[/tex]

[tex]f(d) = 15 + 3d[/tex]

EXACT FORM:

[tex] \frac{93}{80} [/tex]

OR,

MIXED NUMBER FORM:

[tex]1 \frac{13}{80} [/tex]

BOTH ANSWERS ARE CORRECT!

Correct equation is;

x³ - 7x² + 4x + 12 = 0

Answer:

All the real solutions are -1, 2 and 6

Step-by-step explanation:

The x-intercept of x³ - 7x² + 4x + 12 = 0 will occur where y is zero. This is where the curve crosses the x-axis on the graph of this function.

Now, I have plotted a graph of this function and attached it.

From the attached image, the curve crosses the x - axis at the points, x = -1, x = 2, x = 6.

Therefore all the real solutions are -1, 2 and 6

Answer: 3x^2-5x

5x^2-15xy

Step-by-step explanation:

Answer:

3x² - 5x & 5x² - 15 xy

Step-by-step explanation:

1) x(3x - 5)

x × 3x - x × 5 (take the brackets out)

3x² - 5x.

2) 5x (x - 3y)

5x × x - 5x × 3y (take the brackets out)

5x² - 15 xy

Answer:

27°C

Step-by-step explanation:

The temperature on February 9th 1934 = -15°C

The next day the temperature rose 42 degrees.

We need to find an expression for the temperature on February 10th.

February 10th temperature = -15 + 42

= 27°C

So, the temperature on February 10th is 27°C.

Answer: it would be 42+(-15)

$1.98

Step-by-step explanation:

$33.00 x 0.06 = $1.98

Answer:

Step-by-step explanation:

Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3

16 · 3 = 48

to find the price you divide the total price by number of oz.

6.95 ÷ 48 ≈ 0.1448

since money is measured in hundreths, you would round up (because thats how money works) so it would be roughly 15 cents. unless your teacher wants you to round down to 14 cents

Answer:

57.8º

Step-by-step explanation:

According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].

In this triangle we have two sides with two of their angles.

Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.

[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]

Now we multiply both sides by 11 to get rid of the denominator on the left.

sinx = [tex]\frac{11sin38}{8}[/tex]

To find x, we use inverse sine.

x = sin⁻¹ (11sin38/8)

Plug this into a calculator, and you will get 57.837.

Round this to 57.8º
