What is the area of triangle RST

Mathematics
2 answers:
velikii [3]3 years ago

Answer:

9 square units

Step-by-step explanation:

The area of any triangle is given by:

A = 0.5 × Base × Height

From the given graph, the base of the triangle RST is RS and Height is TU

RS = 3-(-3) units = 6 units

TU = 2-(-1) = 3 units

A = 0.5 × RS × TU = 0.5 × 6 × 3 = 9 square units

Thus, area of the triangle RST would be 9 square units.

Algebraically, find all remaining zeros of f(x) = 8x^3 - 6x^2-36x +27 in simplest form.
viva [34]

Answer:

x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}

Step-by-step explanation:

Given expression is,

f(x) = 8x³ - 6x² - 36x + 27

For zeros of the function,

f(x) = 0

8x³ - 6x² - 36x + 27 = 0

2x²(4x - 3) - 9(4x - 3) = 0

(2x² - 9)(4x - 3) = 0

(2x² - 9) = 0

x² = \frac{9}{2}

x = \pm\frac{3}{\sqrt{2}}

x = \pm \frac{3\sqrt{2}}{2}

Or (4x - 3) = 0

x = \frac{3}{4}

Therefore, all zeros of the given functions are  x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}.

The rectangular top of a small box has dimensions of one 40 mm x 230 mm. How long in centimeters with a ribbon need to go all th
kozerog [31]

Answer:

540 mm

Step-by-step explanation:

Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm

We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the

P=2 (l+w)

l = 230

w = 40

P=2(230+40)

P=2 x 270

P= 540

Hence we need 540 mm of ribbon  to go all the way around the edge of the top of the box.

Tamiku [17]

Answer:

The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.

For h>7

C=210+20(h-7)

C=210+20h-140

C=20h+70, h>7

410=20h+70

20h=340

h=17 hours

goldfiish [28.3K]
F(x) = 3ˣ + 10x   and   g(x) = 4x – 2, find (f-g)(x)
(f-g)(x) = f(x) - g(x):

(3ˣ + 10x) - (4x - 2) →→→ 3ˣ + 6x - 2. Then:

(f-g)(x) = 3ˣ + 6x - 2
