Step-by-step explanation:

Given

base (b) = 34 yd

height (h) = 6.3 yd

Area of the triangle

= 1 /2 * b * h

= 1/2 * 34 * 6.3

= 107.1 yd²

Answer:

5x + 15

Step-by-step explanation:

Let's simplify step-by-step.

17−(−5x+2)

Distribute the Negative Sign:

=17+−1(−5x+2)

=17+−1(−5x)+(−1)(2)

=17+5x+−2

Combine Like Terms:

=17+5x+−2

=(5x)+(17+−2)

=5x+15

Answer:

=5x+15

Answer:

-3

Step-by-step explanation

You would first used distribuve property in the parenthisis.

Because there is a minus sign outside of the parenthisis, it would become (5x-2)

Combine like terms

15+5x=0

Subtract 15 from both sides

5x=-15

Divide 5 to get x

5x(/5)= -15(/5)

x=-3

Answer:

-17√2 /26 or -0.9247 to the nearest ten thousandth.

Step-by-step explanation:

The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)

= √13 so sin x = 2/√13 and cos x = 3/√13

sin2x = 2sinxcos

= 2* 2/√13 * 3/√13

= 12/13.

cos2x = cos^2x - sin^2x

= 9/13 - 4/13

= 5/13.

sin(2x + 5π/4)

= sin2x cos5π/4 + cos2x sin5π/4

= 12/13 * -1/√2 + 5/13 * -1/√2

= -12 / 13√2  - 5 / 13√2

= -17/13√2

= -17√2 /26.

Answer:

Option A

Step-by-step explanation:

Option A

f(x) = -3(x + 7)(x + 4),

Remember that to solve for the x-intercepts we equate y to 0,

-3(x + 7)(x + 4) = 0

Using the zero product property,

x + 7 = 0, x + 4 = 0

x = - 7, x = -4

x -intercepts: (- 7, 0) & (- 4, 0)

Hence proved.

Answer:

[tex]E =[/tex] [tex](-3,3)[/tex]

Step-by-step explanation:

Given

Parallelogram: DEFG

[tex]D(x_1,y_1) = (-2,-4)[/tex]

[tex]F(x_3,y_3) = (0,7)[/tex]

[tex]G(x_3,y_4) = (1,0)[/tex]

Required

Find the coordinates of [tex]E(x_2,y_2)[/tex]

To do this, we make use of mid-point formula which is:

[tex]M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})[/tex]

This gives:

[tex](\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]

[tex](\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]

Multiply through by 2

[tex]2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2[/tex]

[tex](-2,3) = (x_2+1,y_2+0)[/tex]

[tex](-2,3) = (x_2+1,y_2)[/tex]

By comparison:

[tex]-2 = x_2 + 1[/tex] and [tex]3= y_2[/tex]

So, we have:

[tex]-2-1=x_2[/tex] and [tex]3= y_2[/tex]

[tex]-3 = x_2[/tex] and [tex]3 = y_2[/tex]

This gives:

[tex]x_2 = -3[/tex] and [tex]y_2 =3[/tex]

Hence, the 4th coordinate is: [tex](-3,3)[/tex]

Just got it right on my test!!

Answer:

h = 1,125

v = 450

Step-by-step explanation:

Total number of seats = 1575

h = number of seats in the home section

v = number of seats in the visitor section

There are two and a half times as many seats in the home section as there are in the visitor section.

h = 2 1/2 * v

h = 2 1/2v

Total = h + v

1575 = 2 1/2v + v

1575 = 3 1/2v

1575 = 7/2v

v = 1575 ÷ 7/2

= 1575 × 2/7

= (1575*2) / 7

= 3150 / 7

= 450

v = 450

h = 2 1/2v

= 5/2*450

= 2250/2

= 1,125

h = 1,125

Answer:

21 hours

Step-by-step explanation:

Step-by-step explanation:

Answer: p = 4.9

Step-by-step explanation:

2,5 + 3(5-2.1p) = -13,37

2,5 + 3(5-2.1p) - 2,5 = -13,37 - 2,5

3(5-2.1p) = -15,87

3(5-2.1p) / 3= -15,87 /3

5-2.1p = -5.9

5+5.29 = 2.1p

(5+5.29 ) /2.1 = 2.1p /2.1

4.9 = p

Answer:

160miles

Step-by-step explanation:

400miles uses15g what about 6g.

Using cross multiplication. Multiply 6x400/15 = 160miles

Answer:

160 miles

Step-by-step explanation:

If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons

400 miles -> 15 gallons

x miles -> 6 gallons

15 * x = 6 * 400

15x = 2400

x = 2400 / 15

x = 160 miles

Step-by-step explanation:

Plato

The cofactors of each entry in the first row of the matrix are

Ac_11 = -13

Ac_12 = 44

Ac_13 = 27

We have to determine the cofactors of each entry in the first row of the matrix.

A set of numbers is arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.

Therefore the cofactors of each entry in the first row of the matrix is

Answer:

x=3

Step-by-step explanation:

it would go over the point 3,7 on the graph with a positive slope

The given inequality is solved to obtain as x ≥ 3.

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The given inequality can be solved as follows,

4x - 5 ≥ 7

Subtract 7 from both sides to obtain,

4x - 5 - 7 ≥ 0

=> 4x - 12 ≥ 0

=> 4x ≥ 12

=> x ≥ 3

The graph for the given inequality is shown as below,    

Hence, the solution for the given inequality is x ≥ 3.

Answer:

13

Step-by-step explanation:

f(x)=2(3x)+1

f(2)=2(3X2)+1

f(2)=2(6)+1

f(2)=12+1

f(2)=13

The value of function f(2) is 13.

Function is a type of relation, or rule, that maps one input to specific single output.

Given function;  f(x) = 2 (3x) + 1

We need to find the value of f(2) .

f(x) = 2(3x)+1

f(2) = 2(3 * 2)+1

f(2) = 2(6)+1

f(2)=12+1
