Here is a rectangle.
9 cm
7 cm
Work out the perimeter of the rectangle.

Answer:

B. The other solution to function [tex]h[/tex] is [tex]-4-i\,7[/tex].

Step-by-step explanation:

From Algebra, we remember that quadratic functions of the form [tex]a\cdot x^{2}+b\cdot x + c[/tex] has solutions of the form:

[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], where both are complex if and only if [tex]\sqrt{b^{2}-4\cdot a \cdot c}< 0[/tex].

Hence, if one solution of the quadratic function is [tex]-4+i\,7[/tex], then the other solution is [tex]-4-i\,7[/tex]. The correct answer is B.

Answer:

68 degrees

Step-by-step explanation:

This triangle is an isosceles triangle which means that two sides have equal lengths and when two sides have equal lengths that means that two angles are the same. so you add 56 and 56 together and you get a sum of 112. all triangles add up to a degree of 180, so you therefore subtract 112 from 180 which gives you an answer of 68 degrees , therefore x is 68

Answer:

-2x - (-1y) - (-3)

Step-by-step explanation:

Answer:

-2x + y + 5

Step-by-step explanation:

(5x - 2y + 1) - (7x - 3y - 4)

1) Distribute the negative sign and remove all parenthesis

5x - 2y + 1 - 7x + 3y + 4

2) Combine all like terms

-2x + y + 5

Answer:

0.1538

Step-by-step explanation:

first convert 3/11 into a percentage

3÷11=0.272727272727273

0.272727272727273 × 100

27.272727272727/100

27.272727272727%

≈27.27%

27.27% of 22/39

change 22/39 into a decimal

22÷39=0.5641025641》0.564

27.27% of 0.564

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 27.27% * 0.564

Converting percent to decimal:

p = 27.27%/100 = 0.2727

Y = 0.2727 * 0.564

Y = 0.1538

Answer:

  128 ft

Step-by-step explanation:

The height of the tower above eye-height is related to the angle by ...

  Tan = Opposite/Adjacent

  tan(72°) = (tower height above eye height)/(40 ft)

  tower height above eye height = (40 ft)×tan(72°) = 123 ft

Since eye height is 5 ft, the total height of the tower from the ground is ...

  tower height = eye height + height above eye height

  tower height = 5 ft + 123 ft

  tower height = 128 ft

Hey there!

Given;

The points is; (-1 , 2) and slope is 4.

Note: Use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

~ Put all values.

[tex](y - 2) = 4(x + 1)[/tex]

~ Simplify it.

[tex](y - 2) = 4x + 4[/tex]

[tex]4x - y + 6 = 0[/tex]

Therefore, the required equation is; 4x-y+6=0.

Answer:

x = 35°

Step-by-step explanation:

From the question given above:

cos x = sin(20 + x)

The value of x can be obtained as follow:

cos x = sin(20 + x)

Recall:

sin(A + B) = sinAcosB + cosAsinB

Therefore,

sin(20 + x) = sin20cosx + cos20sinx

cos x = sin(20 + x)

cos x = sin20cosx + cos20sinx

Collect like terms

cos x – sin20cosx = cos20sinx

cos x(1 – sin20) = cos20sinx

Divide both side by cosx

(1 – sin20) = cos20sinx / cosx

Recall:

Tan x = sinx / cosx

(1 – sin20) = cos20tanx

Divide both side by cos20

(1 – sin20) / cos20 = tanx

(1 – 0.3420) / 0.9397 = tanx

0.658 / 0.9397 = tanx

0.7 = tanx

Take the inverse of tan

x = tan¯ 0.7

x = 35°

Answer:

[tex](x-5)(x+1)(x-2)[/tex]

Step-by-step explanation:

well as a general case we have

when we say that

[tex]x=y[/tex] it gives zero moving the y to the other side we have

[tex]x-y=0[/tex]

so in our case

[tex]\longrightarrow x-5=0\\\\\rightarrow x-(-1)=0\\\\\longrightarrow x+1=0\\\\\longrightarrow x-2=0[/tex]

just multiply the ones that have [tex]\longrightarrow[/tex]

and get

[tex](x-5)(x+1)(x-2)=0[/tex]

Answer:

38 °

Step-by-step explanation:

a triangles total side add up to 180°

so, we subtract 180 - 106 = 74

then we subtract 74-36 = 38°

?= 38°

Answer:

D. <C'D'A'

Step-by-step explanation:

Given that figure ABCD is transformed to figure A′B′C′D′, therefore the angles of ABCD would be congruent to the corresponding angles of A′B′C′D′.

<CDA corresponds to <C'D'A'. Therefore:

<CDA = <C'D'A'

Answer:

Option (4)

Step-by-step explanation:

By applying triangle sum theorem in ΔABC,

m∠A + m∠B + m∠C = 180°

80° + 40° + m∠C = 180°

m∠C = 180° - 120°

m∠C = 60°

Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]

m∠DCE = m∠ACB = 60°

Now by applying triangle sum theorem in ΔCDE,

m∠DCE + m∠CED + m∠CED = 180°

60° + 70° + x° = 180°

x = 180 - 130

x = 50°

Therefore, Option (4) will be the answer.
