(3,4);m=-z in point slope formula

Mathematics

Given:

Point = (3,4)

Slope : m = -z

To find:

The point slope formula.

Solution:

Point slope form: If a line passes through the point $(x_1,y_1)$ and having slope m, then the point slope form of the line is

$y-y_1=m(x-x_1)$

The line passing through the point (3,4) and having slope -z.

Putting $x_1=3,y_1=4, m=-z$ , we get

$y-4=-z(x-3)$

Therefore, the required point slope form is $y-4=-z(x-3)$ .

The radius of a circle is 18 meters. What is the circle's area?

ankoles [38]

Answer:

200.96 sq. meters.

Step-by-step explanation:

The formula for the area of a circle is \pi r^(2). To solve for the area, use the given values, pi is 3.14 and the radius is 18. This gives you the new equation of (3.14)(18)^2. Solve algebraically, first raising the radius to the power of 2, and then multiplying.

1/6 + 3/8 A. 4/6 B. 4/8 C. 4/14 D. 13/24

Naddika [18.5K]

Here is you're answer:

In order to get you're answer you need to find the common denominator then add.

$\frac{1}{6} + \frac{3}{8}$
Find the common denominator:
$CD = 48$
$= \frac{26}{48}$
Simplify:
$\frac{26}{48} \div 2 = \frac{13}{24}$
$= \frac{13}{24}$

Therefore you're answer is option D "13/24."

Hope this helps!

Triangles WSR and TVR are similar. Find x.

Vlad [161]

They are similar. Set the proportions equal to each other

(x + 8)/8 = (x+14)/12

Cross multiply

(x + 8)/8 (8)(12) = (x + 14)/12 (12)(8)

12(x + 8) = 8(x + 14)

Distribute the 12 and 8 to the corresponding monomials inside the parenthesis

12(x + 8) = 12x + 96

8(x + 14) = 8x + 112

12x + 96 = 8x + 112

Isolate the x. Subtract 8x from both sides and 96 from both sides

12x (-8x) + 96 (-96) = 8x (-8x) + 112 (-96)

12x - 8x = 112 - 96

4x = 16

Isolate the equal sign. Divide 4 from both sides

4x/4 = 16/4

x = 16/4

x = 4

Let f(x)= x2 - 14 and g(x) = 6-X. Find (fq)(7).

sleet_krkn [62]

Answer:

$(fg)(7) = - 35$

Step-by-step explanation:

The given functions are:

$f(x) = {x}^{2} - 14$

and

$g(x) = 6 - x$

We want to to find

$(fg)(7)$

Note that:

$(fg)(x) = f(x) \times g(x)$

We substitute the functions to obtain:

$(fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)$

We now substitute x=7, to get:

$(fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)$

This implies that

$(fg)(7) =( 49-1 4 ) \times (6 - 7)$

$(fg)(7) = 35 \times - 1 = - 35$

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away

elixir [45]

Answer:

10.1 miles far is their house.

Step-by-step explanation:

Given:

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away.

Now, to find the distance is far from their house.

14.6 miles distance they ran from their house.

So, they are far from house = $14.6\ miles.$

Then, 9.8 miles they are from their house.

So, they are far from house = $14.6-9.8\ miles=4.8\ miles.$

And, finally 5.3 miles away from their house.

So, now they are far from house = $4.8+5.3=10.1\ miles.$

Therefore, 10.1 miles far is their house.
