Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos33° = $\frac{adjacent}{hypotenuse}$ = $\frac{1.2}{x}$

Multiply both sides by x

x × cos33° = 1.2 ← divide both sides by cos33°

x = $\frac{1.2}{cos33}$ ≈ 1.4 ( to the nearest tenth ) → D

What is the equation of a line that passes through the point (8, −2) and is parallel to the line whose equation is 3x + 4y = 15?

Dafna1 [17]

Step 1

Find the slope of the given line

we have

$3x+4y=15$

Isolate the variable y

Subtract $3x$ both sides

$3x+4y-3x=15-3x$

$4y=-3x+15$

Divide by $4$ both sides

$y=-\frac{3}{4}x+ \frac{15}{4}$

the slope of the given line is

$m=-\frac{3}{4}$

Step 2

Find the equation of the line that passes through the point $(8,-2)$ and is parallel to the given line

we know that

if two lines are parallel, then their slopes are equal

The equation of the line into point-slope form is equal to

$y-y1=m(x-x1)$

we have

$m=-\frac{3}{4}$

$(x1,y1)=(8,-2)$

substitute in the equation

$y+2=-\frac{3}{4}(x-8)$

$y=-\frac{3}{4}x+6-2$

$y=-\frac{3}{4}x+4$ or $3x+4y=16$

therefore

the answer is

$y=-\frac{3}{4}x+4$

$3x+4y=16$

Let f(x) = 2x2 + x − 3 and g(x) = x + 2. Find (f • g)(x)

katen-ka-za [31]

Answer:

$(f\cdot g)(x) = 2x^3 + 5x^2-x-6$

Step-by-step explanation:

We are given the two functions:

$f(x)=2x^2+x-3\text{ and } g(x)=x+2$

And we want to find:

$(f \cdot g)(x)$

Recall that this is equivalent to:

$=f(x)\cdot g(x)$

Substitute. Hence:

$(f\cdot g)(x)= (2x^2+x-3)(x+2)$

Expand if desired:

$\displaystyle = x(2x^2+x-3)+2(2x^2+x-3) \\ \\ = (2x^3+x^2-3x)+(4x^2+2x-6) \\ \\\ = 2x^3 + 5x^2-x-6$

A yardstick casts a shadow of 24 in. at the same time a telephone pole casts a shadow of 20 ft 8 in. What is the height of the t

BabaBlast [244]

1 yd = 36 in; 20 ft 8 in = 248 in;
We will use a proportion:
36 : 24 = x : 248
24 x = 36 * 248
24 x = 8,928
x = 8,928 : 24 = 372
Answer: C ) 372 in
