Amiraneli [1.4K]

Answer:

$1025

Step-by-step explanation:

We can use the 2-point form of the equation of a line to write a function that gives Justin's salary as a function of his sales.

We start with (sales, salary) = (400, 500) and (700, 575)

The 2-point form of the equation of a line is ...

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

salary = (575 -500)/(700 -400)(sales -400) +500

salary = 75/300(sales -400) +500

For sales of 2500, this will be ...

salary = (1/4)(2500 -400) +500 = (2100/4) +500 = 1025

Justin's salary after selling $2500 in merchandise is $1025.

The lengths of the sides of a square are 5 cm. find the length of the diagonal

jenyasd209 [6]

Answer:

square root (50) = 7.071

Step-by-step explanation:

Using Pthagoras' theorem, the diagonal length is $\sqrt{x} ax^{2} +bx^{2}$ .

Therefore, the diagonal length is the square root of 5^2+5^2,

= $\sqrt{x} 25+25$

= $\sqrt{x} 50$

= 7.071

Calculate x Give your answer correct to 1 d.p. Х 35° 15 cm<br> it is a trigonometry question.

OlgaM077 [116]

Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.

So let's do cos(35°) = 15cm / x

cos(35°) = 0.8 (1 dp)

x = 15 cm / cos(35°)

x = 18.3 cm (1 dp)

Answer:

x ≤ - 27

Step-by-step explanation:

$\frac{x}{-9}\ge \:3\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\\\frac{x\left(-1\right)}{-9}\le \:3\left(-1\right)\\\\Simplify\\\\\frac{x}{9}\le \:-3\\\\\mathrm{Multiply\:both\:sides\:by\:}9\\\\\frac{9x}{9}\le \:9\left(-3\right)\\\\\mathrm{Simplify}\\\\x\le \:-27$
