Answer:

$15t > 180$

Step-by-step explanation:

the girl is selling tickets for dollars 15 and she wants to raise more than dollars 180. that means we need a symbol that will make it so that $180 is always less than. like such.

$180 < y \\ y > 180$

it shouldn't be less than or equal to symbol because she wanted to save more than $180. that means we can't use this expression.

$15 + t \geqslant 180 \\ 15t \geqslant 180$

and we can't use this expression either

$15 + t > 180$

let's say if we had somebody by one ticket then that would mean we would add 1 to 15 which will equal 16 and so forth.

$15 + 1 = 16 \\ 15 + 2 = 17 \\ 15 + 3 = 18$

etc....

if each one of her tickets cost $15 and t is equal to the amount of tickets sold then we should multiply the operation so that we have groups of 15. like such.

$15 \times 1 = 15 \\ 15 \times 2 = 30 \\ 15 \times 3 = 45 \\ 15 \times 4 = 60$

etc....

this means the expression she wants to use is

$15t > 180$

if you want more help you can ask me and I will try to answer your questions.

The product of 2 and a number x is 3/4 .

Vikki [24]

The appropriate algebraic equation is 2x = 3/4. To solve this for x, multiply both sides of this equation by (1/2), obtaining x = (1/2)(3/4) = 3/8 (answer)

Calculate two iterations of Newton's Method for the function using the given initial guess. (Round your answers to four decimal

pickupchik [31]

Answer:

The first and second iteration of Newton's Method are 3 and $\frac{11}{6}$ .

Step-by-step explanation:

The Newton's Method is a multi-step numerical method for continuous diffentiable function of the form $f(x) = 0$ based on the following formula:

$x_{i+1} = x_{i} -\frac{f(x_{i})}{f'(x_{i})}$

Where:

$x_{i}$ - i-th Approximation, dimensionless.

$x_{i+1}$ - (i+1)-th Approximation, dimensionless.

$f(x_{i})$ - Function evaluated at i-th Approximation, dimensionless.

$f'(x_{i})$ - First derivative evaluated at (i+1)-th Approximation, dimensionless.

Let be $f(x) = x^{2}-8$ and $f'(x) = 2\cdot x$ , the resultant expression is:

$x_{i+1} = x_{i} -\frac{x_{i}^{2}-8}{2\cdot x_{i}}$

First iteration: ( $x_{1} = 2$ )

$x_{2} = 2-\frac{2^{2}-8}{2\cdot (2)}$

$x_{2} = 2 + \frac{4}{4}$

$x_{2} = 3$

Second iteration: ( $x_{2} = 3$ )

$x_{3} = 3-\frac{3^{2}-8}{2\cdot (3)}$

$x_{3} = 2 - \frac{1}{6}$

$x_{3} = \frac{11}{6}$

ASAP!!!!!!!!! PLEASE help me with this question! This is really urgent! No nonsense answers please.

Answer:

Because <CBD is an inscribed angle and <CAD is a central angle with the same intercepted arc, m<CBD = 55°, or half of the measure of <CAD.

Step-by-step explanation:

The Inscribed Angle Theorem proves that an inscribed angle is half the measure of a central angle, if both the inscribed angle and the central angle intercepts the same arc.

Also, according to the inscribed angle theorem, an inscribed angle is ½ of the measure of the arc it intercepts.

Therefore, m<CBD is half of m<CAD, or half of the measure of the arc CD that they both intercept together.

Thus, m<CBD = 55°, which is ½ of m<arc CD.

m<arc CD = 110° = m<CAD.

m<CBD = ½ of m<CAD = 55°.

The statement that best describes the relationship between <CBD and <CAD is "Because <CBD is an inscribed angle and <CAD is a central angle with the same intercepted arc, m<CBD = 55°, or half of the measure of <CAD."
