Answer:

h = 7

Step-by-step explanation:

-3h + 6 = -15

Get rid of the 6 by subtracting it from both sides.

-3h + 6 - 6 = -15 - 6

-3h = -21

Get rid of the -3 by dividing it from both sides.

-3h/-3 = -21/-3

h = 7

Answer:

A. Between 3.0 and 3.5 and between 4.0 and 4.5

Step-by-step explanation:

The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either [tex]f(x)[/tex] goes from a negative value to a positive value or vice versa.

From [tex]x=3.0[/tex] and [tex]x=3.5[/tex], the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.

From [tex]x=4.0[/tex] and [tex]x=4.5[/tex], the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.

Thus, the zeros of this function occur between 3.0 and 3.5 and between 4.0 and 4.5, leading to answer choice A.

Answer:

between 3.0 and 3.5 and between 4.0 and 4.5

Answer:

S2 + 355

Step-by-step explanation:

Given the expression to evaluate :

S2+54+18+46+237

Since the values are bound by the addition operator, we take the sum of the like terms ;

S2 + (54+18+46+237)

S2 + 355

Answer:

-4

Step-by-step explanation:

Slope is found by

Answer:

Step-by-step explanation:

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

Dilation is the increase or decrease in size of a figure by a factor k. If k > 1, then the dilation is an increase whereas if k<1, then the dilation is a decrease.

From the diagram, since triangle LMN is dilated by a factor of 1/4, hence the size of LMN is reduce. Therefore:

L'M' = (1/4)LM, L'N' = (1/4)LN, N'M' = (1/4)NM

Also, the distance from point P to N' is one-fourth of the distance from point P to N.

The correct option is highlighted in the image attached.

Answer:

188.57 cm³

Step-by-step explanation:

Half sphere = 1/2 volume sphere

Sphere = 4/3 * 22/7 * 3³

Sphere = 4/3 * 22/7 * 27/1

Sphere = 2376/21 = 113.14

113.14 / 2 = 56.57

Cone = 22/7 * 3² * h/3

Cone = 22/7 * 9/1 * 14/3

Cone = 2772/21 = 132

132 + 56.57 = 188.57 cm³

Answer:

Step-by-step explanation:

a) 5 = 5

10 = 2 * 5

40 = 2 * 2 * 2 *5

Least common denominator = 2*2*2*5=40

Now find equal fractions with denominator 40

[tex]\frac{2}{5}=\frac{2*8}{5*8}=\frac{16}{40}\\\\\frac{7}{10}=\frac{7*4}{10*4}=\frac{28}{40}\\\\\frac{9}{40}[/tex]

Fractions with equal denominators:

[tex]\frac{16}{40} ; \frac{28}{40} ; \frac{9}{40}[/tex]

b) 25 = 5* 5

40 =  2 * 2 * 2 * 5

120 = 2 * 2 * 2 * 3 * 5

Least common denominator = 8*25*3=600

[tex]\frac{17}{25}=\frac{17*24}{25*24}=\frac{408}{600}\\\\\frac{23}{40}=\frac{23*15}{40*15}=\frac{345}{600}\\\\\frac{67}{120}=\frac{67*5}{120*5}=\frac{335}{600}\\\\[/tex]

Step-by-step explanation:

24 = 4*6

But 4 and 6 aren't prime

24 = 4*6 = (2*2)  * (2*3)

All these numbers are prime

24 = 2*2*2*3  or with exponents  = 2^3   * 3

Answer:

22.50m

Step-by-step explanation:

With the ground, the horizontal ground distance is the adjacent side, so by SOHCAHTOA, the ratio used is cosine, i.e.

Ground distance

= hypotenuse * cos(50°)

= 35 cos(50°)

= 35*0.64279

= 22.50m

Answer:

Step-by-step explanation:

I'm assuming that you are solving for x, since there's nothing else you can do with this mathematically.

[tex]\frac{1}{2}x=-9[/tex] and the goal is to get the x all alone. So we have to lose the fraction. Do that by multiplying by the reciprocal of 1/2 which is 2/1 (a reciprocal is just a fraction flipped upside down). BUT...because this is an equation, what you do to the left side has to be done to the right side too. Like this:

[tex](\frac{2}{1})\frac{1}{2}x=\frac{-9}{1}(\frac{2}{1})[/tex]

On the left, everything cancels out but the x (which is why we do this), and on the right we multiply straight across the top and straight across the bottom to get

[tex]x=\frac{-18}{1}[/tex] which is

x = -18
