Which of these is a point-slope equation of the line that is perpendicular to y-25=2(x-10) and passes through (-3,7)

OLEGan [10]

Y = 2x +13

We know the slope to be 2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and the known point.

y = mx + b ----> Input known values
7 = (2)(-3) + b ---> Multiple
7 = -6 + b ----> Subtract 3 from both sides
13 = b

Now we can use the y-intercept found and the slope to write the equation above.

I’m not sure the answer. help!!

MAVERICK [17]

Answer:

x = {-5π/4, -3π/4, 3π/4, 5π/4}

Step-by-step explanation:

You know that sec(x) = 1/cos(x), so this is equivalent to ...

cos(x) = -1/√2

The cosine has a magnitude of 1/√2 for an angle of 45°, or π/4 radians. It is negative in the 2nd and 3rd quadrants. Angles in those quadrants that have a reference angle of π/4 are ...

3π/4, 5π/4

We also want angles in the range -2π to 0, so all of the solutions will be ...

sec(x) = -√2 for x = {-5π/4, -3π/4, 3π/4, 5π/4}

We like to use the x-intercept as the solution when graphing, so we write the given equation as ...

sec(x) +√2 = 0

The graph verifies the above solutions.

Answer:

The smallest model - bottom right - in the question diagram represents $\sqrt[3]{64}=4$ .

Step-by-step explanation:

Considering the radical expression

$\sqrt[3]{64}$

Lets simply this radical expression first

$\sqrt[3]{64}$

$\mathrm{Factor\:the\:number:\:}\:64=4^3$

$=\sqrt[3]{4^3}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a,\:\quad \:a\ge 0$

$\sqrt[3]{4^3}=4$

$=4$

Therefore, $\sqrt[3]{64}=4$

Now, as we can determine that $\sqrt[3]{64}=4$ . So, the smallest model in the question diagram represents $\sqrt[3]{64}=4$ as each face of the cube of the smallest model in the diagram - bottom right - has 4 squares.

Therefore, the smallest model - bottom right - in the question diagram represents $\sqrt[3]{64}=4$ .
