the third part lol helppppppppppppppppppppppppppppppppppppppppp

Answer:

The two marked in the image.

Step-by-step explanation:

In scientific notation you will want only the most significant non-zero digit before the comma.

The first underlined number has two digits before it, the correct representation should be [tex]1.25\times10^4[/tex]

The second underlined number has a 0 leading digit, while the most significant non-zero digit is a 4. The correct represantation should be [tex]4.5\times 10^2[/tex]

An extra case could be made for the second number of the list, since it has no decimal part, but the way I read it means "the instrument used to measure the data has 0 decimal places accuracy"

Answer:

One possible equation is [tex]f(x) = (x + 3)\, (x - 5)[/tex], which is equivalent to [tex]f(x) = x^{2} - 2\, x - 15[/tex].

Step-by-step explanation:

The factor theorem states that if [tex]x = x_{0}[/tex]  (where [tex]x_{0}[/tex] is a constant) is a root of a function, [tex](x - x_{0})[/tex] would be a factor of that function.

The question states that [tex](-3,\, 0)[/tex] and [tex](5,\, 0)[/tex] are [tex]x[/tex]-intercepts of this function. In other words, [tex]x = -3[/tex] and [tex]x = 5[/tex] would both set the value of this quadratic function to [tex]0[/tex]. Thus, [tex]x = -3\![/tex] and [tex]x = 5\![/tex] would be two roots of this function.

By the factor theorem, [tex](x - (-3))[/tex] and [tex](x - 5)[/tex] would be two factors of this function.

Because the function in this question is quadratic, [tex](x - (-3))[/tex] and [tex](x - 5)[/tex] would be the only two factors of this function. In other words, for some constant [tex]a[/tex] ([tex]a \ne 0[/tex]):

[tex]f(x) = a\, (x - (-3))\, (x - 5)[/tex].

Simplify to obtain:

[tex]f(x) = a\, (x + 3)\, (x - 5)[/tex].

Expand this expression to obtain:

[tex]f(x) = a\, (x^{2} - 2\, x - 15)[/tex].

(Quadratic functions are polynomials of degree two. If this function has any factor other than [tex](x - (-3))[/tex] and [tex](x - 5)[/tex], expanding the expression would give a polynomial of degree at least three- not quadratic.)

Every non-zero value of [tex]a[/tex] corresponds to a distinct quadratic function with [tex]x[/tex]-intercepts [tex](-3,\, 0)[/tex] and [tex](5,\, 0)[/tex]. For example, with [tex]a = 1[/tex]:

[tex]f(x) = (x + 3)\, (x - 5)[/tex], or equivalently,

[tex]f(x) = x^{2} - 2\, x - 15[/tex].

Answer:

Step-by-step explanation:

We already know that both triangles have a congruent side length.

We also know angle KVM or UVW are the same

We only have to know if VM and WV are the same.

This way, each triangle will have two congruent side lengths and a angle. The third side will therefore be the same.

By the same logic, if we know that KM and UW are the same, the two triangles are also congruent.

To determine if two triangles are congruent using the SAS (Side-Angle-Side) criterion, we need additional information about the length of one side, the measure of one angle, and the length of another side in both triangles.

This information is crucial in order to establish the congruence between the triangles. For example, let's consider two triangles, triangle ABC and triangle DEF. To prove that these triangles are congruent using the SAS criterion, we need to know: 1. The length of side AB in triangle ABC and the length of side DE in triangle DEF. 2. The measure of angle A in triangle ABC and the measure of angle D in triangle DEF. 3. The length of side BC in triangle ABC and the length of side EF in triangle DEF. By knowing these measurements, we can compare the corresponding sides and angles of the two triangles. If the lengths of the corresponding sides are equal and the measures of the corresponding angles are equal, then we can conclude that the two triangles are congruent by the SAS criterion.

x = 5 , y = 2

Step-by-step explanation:

3y + 4y + 2x = 24

(3y)² + (4y)² = (2x)²

2x + 7y = 24 .............. (1)

25y² = 4x² ................ (2)

x = [tex]\frac{5}{2}[/tex] y   ------>  (1)  

2 ( [tex]\frac{5}{2}[/tex] y ) + 7y = 24

12y = 24

y = 2 ----------> (1)

The value of q when q varies inversely with p is 2.

The formula that can be used to represent inverse variation is:

p = k/q

Where:

The first step is to determine the value of the constant of proportionality

k = p x q

k = 15 x 4 = 60

Given the value of the  constant of proportionality, the value of q can now be determined.

30 = 60/q

q = 60 / 30

q = 2

Step-by-step explanation:

Step 1:  Determine important information

Using the given numbers it doesn't really matter which is which because the equation multiplies everything together.

Surface Area of a Rectangular Prism → [tex]S= 2(wl+hl+hw)[/tex]

Step 2:  Plug in the values and solve

[tex]S = 2((10\ in * 4\ in) + (7\ in * 4\ in) + (7\ in * 10\ in))[/tex]

[tex]S=2(40\ in^2 + 28\ in^2 + 70\ in^2)[/tex]

[tex]S = 2(138\ in^2)[/tex]

[tex]S = 276\ in^2[/tex]

Answer:

A die has 6 numbers.

So 6 numbers them being
1, 2, 3, 4, 5, 6

There’s only one number greater then 5 which is 6.
Since its 6 numbers, a die has a 1/6 chance of getting your desired number.

So it’s a 1/6 chance.

Answer:

y=6x-4

(dark blue)

Step-by-step explanation:

x=0 y=-4

y=6x-4

y=6(0)-4

y=-4

0.7 as a fraction:

1) x = 5

2) x = 2

3) n = 6

4) n = 7

5) y = 12

[tex]4x+3=23[/tex]

→[tex]4x = 23 - 3[/tex]

→[tex]4x = 20[/tex]

→[tex]x = \frac{20}{4} [/tex]

→[tex]x = 5[/tex]

Hence, value of x is 5

[tex]24x - 18=30[/tex]

=>[tex]24x = 30 + 18[/tex]

=>[tex]24x = 48[/tex]

=>[tex]x = \frac{48}{24} [/tex]

=>[tex]x = 2[/tex]

Hence, value of x is 2

[tex]160+10n=220[/tex]

[tex]→10n = 220 - 160[/tex]

[tex]→10n =60[/tex]

[tex]→n = \frac{60}{10} [/tex]

[tex]→n = 6[/tex]

Hence, value of n is 6

[tex]51=30+3n[/tex]

[tex]→51 - 30 = 3n[/tex]

[tex]→21 = 3n[/tex]

[tex]→\frac{21}{3} = n[/tex]

[tex]→n = 7[/tex]

Hence, the value of n is 7

[tex]6y + 85=157[/tex]

[tex]→6y = 157 - 85[/tex]

[tex]→6y = 72[/tex]

[tex]→y = \frac{72}{6} [/tex]

[tex]→y = 12[/tex]

Hence, value of y is 12
