I need help guys :)))

Answer:

[tex]7^{14}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex]7^{6}[/tex] × [tex]7^{8}[/tex] = [tex]7^{(6+8)}[/tex] = [tex]7^{14}[/tex]

Answer:

46.6%

Step-by-step explanation:

1500 is 100%

700 is x

multiple 700 to 100 the answer is 70000 and divide it by 1500 the percent is 46.6

Step-by-step explanation:

Probably wrong I literally just searched it up.

Answer:

[tex]y=\frac{1}{2}x+3[/tex]

Step-by-step explanation:

Let y equal the total amount of time spent on homework. Regardless of Shaunda's time spent on homework, represented by x, Zack spends half the time, represented by the 1/2. The additional 3hrs represents the y intercept, making it added on to the 1/2x expression.

If I helped, a brainliest answer would be greatly appreciated!

Answer:

8x^3 + 22x^2 - 4x

Given:

The graph of a function.

To find:

The vertex form of the function.

Solution:

The graph is a U-shaped curve or a parabola with vertex at [tex](-3,-1)[/tex].

The parent function for vertical parabolas is [tex]f(x)=x^2[/tex] with vertex at (0,0).

It means the graph of [tex]f(x)=x^2[/tex]  translated 3 units left and 1 unit down the get the given graph.

The vertex form of a parabola is:

[tex]y=a(x-h)^2+k[/tex]

Where, a is a constant and (h,k) is vertex.

The vertex of the given parabola is at [tex](-3,-1)[/tex]. So, [tex]h=-3,k=-1.[/tex].

[tex]y=a(x-(-3))^2+(-1)[/tex]

[tex]y=a(x+3)^2-1[/tex]            ...(i)

The graph passes through point (-2,0). Putting [tex]x=-2,y=0[/tex], we get

[tex]0=a(-2+3)^2-1[/tex]

[tex]1=a(1)^2[/tex]

[tex]1=a[/tex]

Putting [tex]a=1[/tex] in (i).

[tex]y=1(x+3)^2-1[/tex]

[tex]y=(x+3)^2-1[/tex]

Therefore, the vertex form of the given graph is [tex]y=(x+3)^2-1[/tex].

9.43

Step-by-step explanation:

c=a2+b2=82+52≈9.43398

Answer:

a) 21 √m inches

b) 13√2/2 m

Step-by-step explanation:

a) we want to find the perimeter of an equilateral triangle

An equilateral triangle is one which sides has the same equal length

The perimeter of this triangle is the sum of the lengths of the three sides

Mathematically, we have this as:

7 √m + 7 √m + 7 √m

= 21 √m inches

b) we want to calculate the perimeter of the given rectangle

Mathematically, we can calculate the perimeter of a rectangle using the formula below;

P = 2(l + b)

where l represents the length of the rectangle and b represents the breadth of the rectangle

From the given shape;

l = √50 m, b = 1/2 √32

So, we have the perimeter follows;

2( √32/2 + √50)

= √32 + √50/2

√32 = 4√2

√50 = 5√2

Thus, we have;

4 √2 + 5 √2/2

= (8 √2 + 5 √2)/2 = 13√2/2

Answer: the III

Step-by-step explanation: because rectangles are a type of quadrilaterals

Answer:

The answer is Some quadrilaterals are rectangles.

Step-by-step explanation:

A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.

Answer:

a run of 6

Explanation:

AB=4 , AC=3

If you create a rise of 8 you doubled the rise of AB [4x2], so you would double the run of AC as well [3x2] = 6

Answer:

<

Step-by-step explanation:

Answer:

The 2 triangles on the right and left are isosceles, so they have 2 equal sides. Consequently, the angles at the base are equal.

Because the opposite angles of a vertix are equal, the triangle in the lower part has the angles x, 58° and 47°.

Because the sum of the inner angles of a triangle is 180, x= 180- (58+47)

x= 180-105 = 75°

Pls mark as brainliest

Answer: x = 72

Step-by-step explanation:

The triangle with ∠a is an isosceles triangle; the other two angles are congruent, let them be y

a + y + y = 180 (sum of angles in triangles)

58 + 2y = 180

Subtract 58 from both sides

2y = 122

Divide both sides by 2

y = 61°

In the triangle with ∠b, b is congruent to another angle, (isosceles triangle) let it be b.

b = 47°

y and b have a relationship with the other two of the angles with ∠x (vertical angles); let them be y and b.

y + b + x = 180

61 + 47 + x = 180

108 + x = 180

Subtract both sides by 108

x = 72

Length of the ladder = 13 m

Foot of the ladder from the wall = 5 m.

The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.

In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.

In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.

In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.

So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.

Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m

wall ^ 2 + ground ^ 2 = 13^2 = 169

w^2 + g^2 = 169

w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12

Rate of change of ground distance = dg / dt = 2m/s (given).

In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.

2 w dw/dt + 2 g dg/dt = 0

2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0

dw/dt = -20 / 24 = -5 / 6

Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)

The minus sign denotes that the height of the ladder is falling.
