X squared + 3X -27/4 = 0

Answer:

a=14

Step-by-step explanation:

32/a=12.8/5.6

a(32/a)=(12.8/5.6)a

32=12.8/5.6a

5.6a(32)=(12.8/5.6a)5.6a

12.8a=179.2 or a = 179.2/12.8

a=14

Answer:

C

Step-by-step explanation:

Answer:

45

Step-by-step explanation:

The formula for finding the longest size of a right angle is

[tex]c^{2} = a^{2} + {b}^{2}[/tex]

a = 28, b = ? and c = 53;

Therefore, if you make b the subject of the formula, you will have

[tex]b = \sqrt{ {c}^{2} - {a}^{2} } [/tex]

And after plugging the value of c=53 and a=28, b is gotten to be 45

A negative num

Answer:

x = -6

Step-by-step explanation:

Answer:

x=-6

Step-by-step explanation:

-2x - 14 = -2

first, you have to add 14 to both sides

-2x = 12

now you divide -2 from both sides

x = -6

Answer:

1 and 5

Step-by-step explanation:

s = smaller number

l = larger number = 2 + 3s

2 + 3s - 1s = 4

2 + 2s = 4

2s = 2

s = 1

l = 2 + 3(1)

l = 5

Answer: 1.6 * 10² shares

Step-by-step explanation:

Number of shares company has = 2.4 * 10⁶

Number of shareholders = 1.5 * 10⁴

Number of shares each shareholder owns:

= 2.4 * 10⁶/1.5 * 10⁴

= 2.4/1.5 * 10⁶⁻⁴

= 1.6 * 10²

Step-by-step explanation:

When b = 5,

4b² = 4(5)² = 4 * 5 * 5 = 100.

Answer:

100 is the right answer.

Step-by-step explanation:

Given that b=5

4b² = 4(5)² = 4×25 = 100

Answer:

[tex]12 * (2 - 3) + (4 * 2)[/tex]

Step-by-step explanation:

Follow PEMDAS for the given answer.

PEMDAS is the order of operation, and is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

Reverse solve the answer so that the result is the question.

First, solve the parenthesis:

12 * (2 - 3) + (4 * 2)

12 * (-1) + 8

Next, multiply 12 and -1 together:

12 * -1 = -12

Finally, add:

-12 + 8 = -4

12 * (2 - 3) + (4 * 2) is your answer.

[tex]12 \times (2 - 3) + (4 \times 2)[/tex]

Step-by-step explanation:

Add parentheses to the following equation to make it true.

[tex]12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times (2 - 3) + (4 \times 2)[/tex]

[tex] = 12 \times ( - 1) + 8[/tex]

[tex] = - 12 + 8[/tex]

[tex] = - 4[/tex]

Answer:

80%

Step-by-step explanation:

The actual value measurement = 4

Estimated value of the measurement= 4.8

percent error= (Estimated value - actual value) ×100%

= (4.8-4)×100%

=0.8×100%

=80%

Hence, Isaiah's percent error is 80%

Answer:

20%

Answer:

(- 1, - 9 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ) , so

(- 9, 1 ) → (- 1, - 9 )

The image of the point (-9, 1) after a rotation of 90° counterclockwise about the origin is (1, 9).

Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).

The given coordinate point is (-9, 1).

Rule: (x, y)→(y, -x)

The image of the point (-9, 1) is

(-9, 1)→(1, 9)

Therefore, the image of the point (-9, 1) after a rotation of 90° counterclockwise about the origin is (1, 9).

Answer:

84dog cubes

Step-by-step explanation:

First we need to get the volume of the rectangular prism and the little cubes

Volume of the prism = base area × height

Volume f the prism = length × width × height

Given

Length = 7/4in

Width = 9/4in

Height = 3in

Volume of the prism = 7/4×9/4×3

Volume of the prism = 63/48

Volume of the prism= 21/16 in³

Volume of the cube = L³

L is the length of one side of the cube

Volume of the cube =(1/4)³

Volume of tje cube = 1/64in³

Number of dog food cubes that will fit in = 21/16÷1/64

= 21/16×64/1

= 21×4

= 84

Hence 84 dog cubes will fit in

Answer:

20.5 this is the answer 10.25 divided by 0.5

Answer:

The answer is below

Step-by-step explanation:

The question is not complete but i would show how to solve.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, rotation, translation and reflection.

Dilation is the enlargement or reduction in the size of a figure.

a) If an point A(x, y) is dilated by a factor k, the new coordinate is A'(kx, ky). From the above options the ones that represent dilation is (x, y) → (0.5x, 0.5y)  and (x, y) → (2x, 2y) . If the object is reduced then the correct option is (x, y) → (0.5x, 0.5y)   while if the object is enlarged the correct option is (x, y) → (0.5x, 0.5y)

b)Dilation is the enlargement or reduction in the size of a figure by a factor k. If k < 1, then it is a reduction and if k > 1, it is an enlargement.

Since Triangle XYZ is dilated with the origin as the center of dilation using the rule (x, y)⇒(0.5x, 0.5y) to create Triangle X’Y’Z’, since the factor is less than 1(0.5 < 1), it is a reduction. Hence Triangle X’Y’Z’ is smaller than Triangle XYZ, because the scale factor is less than 1

c) The dilation creates a smaller figure hence the factor of dilation should be less than 1.

Answer:

2x+15=33

Step-by-step explanation:

Computation of the equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day

Based on the information given the EQUATION will be :

2x+15=33

Where,

x represent Jerry Sit up numbers of days excluding the first day

2x represent the additional 2 more sit ups

2x +15 represent the total number of sit up that was done after the first day

2x+15=33 represent the total 33 sit-ups that jerry did today

Therefore the EQUATION that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day will be 2x+15=33

Answer:

TS is 1

Step-by-step explanation:

The given parameters are;

ΔMNP is similar to ΔTSR

[tex]\overline {NQ}[/tex] and [tex]\overline {SU}[/tex] are angle bisectors of ∠MNP and ∠TSR respectively

MN = 2, TS = n + 2, NP = 3, SU = 1, NQ = n + 3

We have;

MN and TS are corresponding sides

[tex]\overline {NQ}[/tex] and [tex]\overline {SU}[/tex] are corresponding sides

Therefore, we have;

MN/TS = [tex]\overline {NQ}[/tex]/[tex]\overline {SU}[/tex]  which gives;

2/(n + 2) = (n + 3)/1

(n + 2)·(n + 3) = 2

n² + 3·n + 2·n + 6 = 2

∴ n² + 5·n + 4 = 0, which gives, by factorization;

(n + 1)·(n + 4) = 0

∴ n - 1 or n = -4

TS = n + 2

When n = -1 TS = -1 + 2 = 1

When n = -4, TS = -4 + 1 = -3

Therefore, for a natural number value, we have, n = -1 and TS = 1.

Answer:

C

Step-by-step explanation:

Answer:

1) The roots of the equation Y = -x² - 12·x - 37 are x = -6 - √73 and -6 + √73

2) The factors of the function Y = -x² - 12·x - 37 are (x + (-6 - √73)) and (x - (-6 + √73))

3) The vertex is (-6, -1)

4) The Y-intercept is (0, -37)

5) The axis of symmetry is x = -6

6) The parabola opens downward

7) The maximum point is (-6, -1)

8) The graph of the function created with Microsoft Excel is attached

9) The domain of the function is -∞ < x < ∞

10) The range of the function is -∞ < Y ≤ -1

Step-by-step explanation:

The given function is Y = -x² - 12·x - 37

1) The roots of the equation Y = -x² - 12·x - 37 is given as follows;

0 = -x² - 12·x - 37

∴ -x² - 12·x - 37 = 0

The roots are;

x = (12 ± √((-12)² - 4 × 1 × (-37)))/(-2)

∴ x = -6 - √73 and -6 + √73

2) The factors are (x + (-6 - √73)) and (x - (-6 + √73))

3) The vertex is given by h = -b/(2·a) = 12/(2) = -6

k = c - b²/(4·a) = -37 - 144/(-4) = -1

The vertex = (h, k) = (-6, -1)

4) The intercept with the "Y" axis is given when x = 0, therefore, the y-intercept is (0, -37)

5) The axis of symmetry can be found at the vertex or the line x = -6

6) The sign of the coefficient of x² is negative therefore, the parabola opens downward

7) The maximum point is given as follows;

At the maximum point, dY/dx = d(-x² - 12·x - 37)/dx = -2·x - 12 = 0

x = 12/(-2) = -6, which is the vertex, therefore Y = -(-6)² - 12×(-6) - 37 = -1

The maximum point is the vertex (-6, -1)

8) Please find attached the graph of the function created with Microsoft Excel

9) The domain of the function is -∞ < x < ∞

10) The range of the function is -∞ < Y ≤ -1
