Answer:

x = 33

Step-by-step explanation:

x = (135 - 69)/2    Tangent Secant Product

x = 66/2

x = 33

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set. if you need a video Explanation https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode

Answer:

C. Sequence 2 is arithmetic and Sequence 1 is geometric.

Step-by-step explanation:

Arithmetic sequence is where number is continuously increased or decreased in same amount we can see that the second sequence is decreases by 20 continuously

Geometric sequence is where a number is continuously divided or multiplied by same number

we can see that the first sequence is continuously multiplied by (-2)

[tex]3x^{2} +8x+5[/tex]

Answer:

3x²+8x+5

Step-by-step explanation:

Hi there!

We're given the product of two binomials: (3x+5)(x+1) and we want to express as a trinomial (polynomial with 3 terms)

we can multiply using FOIL; firsts, outers, inners, and lasts

Let's start by multiplying the firsts, which are the first terms in the two binomials, which are (3x+5) and (x+1)

So we'll multiply:

3x*x=3x²

Now we'll multiply the outers, which are the terms on the "outside" in the binomials, which are (3x+5) and (x+1)  (remember to include the sign!)

So we'll multiply:

3x*1=3x

then we'll multiply the inners, which are the terms on the "inside" of the binomials, which are (3x+5) and (x+1)

So we'll multiply:

5*x=5x

finally, we'll multiply the lasts, which are the last terms in the binomials, or (3x+5) and (x+1)

So we'll multiply:

5*1=5

now let's add up everything:

3x²+5x+3x+5

we have some like terms that we can combine

3x²+8x+5

Hope this helps!

Answer:

x = 8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos 60 = adj side/ hypotenuse

cos 60 = 4/x

x cos 60 = 4

x = 4 / cos 60

x = 4 / .5

x = 8

Answer:

x = 8 cm

Step-by-step explanation:

To solve it ,given that it is a right angled triangle.

We can use trigonometry functions

cos 60° = adjacent side / hypotenuse

cos 60° = 4 cm / x

multiply each side by x

x × cos 60° = 4 cm × x / x

x cos 60° = 4 cm

divide each side by cos 60°

x × cos 60°/cos 60° = 4 cm / 60°

x = 4 cm / 0.5 . .( given :- cos 60° =0.4 )

x = 8 cm

Answer:

[tex]x=60^{\circ}[/tex]

Step-by-step explanation:

The angle formed by [tex]48+x[/tex] and the angle marked as [tex]72^{\circ}[/tex] are co-interior angles and therefore must be supplementary (add up to 180 degrees).

Therefore, we have:

[tex]48+x+72=180,\\x+120=180,\\x=\boxed{60^{\circ}}[/tex]

Answer:

3 Blue Umbrellas

Step-by-step explanation:

Given

[tex]B \to Blue[/tex]

[tex]Y \to Yellow[/tex]

[tex]R \to Red[/tex]

From the question, we have:

[tex]Y + R = 6[/tex] ---- i.e. 6 are not blue

[tex]B + R = 6[/tex] ---- i.e. 6 are not yellow

[tex]B + Y = 6[/tex] ---- i.e. 6 are not red

Required

The number of blue umbrellas

Make B the subject in: [tex]B + Y = 6[/tex]

[tex]B = 6 - Y[/tex]

Substitute: [tex]B = 6 - Y[/tex] in [tex]B + R = 6[/tex]

[tex]6 - Y + R = 6[/tex]

Collect like terms

[tex]R - Y = 6 - 6[/tex]

[tex]R - Y = 0[/tex]

Rewrite:

[tex]R = Y[/tex]

Substitute [tex]R = Y[/tex] in [tex]Y + R = 6[/tex]

[tex]Y + Y = 6[/tex]

[tex]2Y = 6[/tex]

Divide both sides by 2

[tex]Y=3[/tex]

Recall that: [tex]B = 6 - Y[/tex]

[tex]B = 6 - 3[/tex]

[tex]B = 3[/tex]

Answer:

y2 = m(x2-x1)+y1

Step-by-step explanation:

Given the expression;

m = y2-y1/x2-x1

Making y2 the subject of the formula

Cross multiply

m(x2-x1) = y2-y1

Add y1 to both sides

m(x2-x1)+y1 = y2-y1+y1

m(x2-x1)+y1 = y2

Hence y2 = m(x2-x1)+y1

Answer:

slope = 1

Step-by-step explanation:

A standard linear function is

y = mx + b

where m = slope, b = initial value

Given y = x + 6

slope m = 1, b = 6

Slope of a line parallel to the given line should have the same slope, therefore slope required is m = 1.

Answer:

Volume of the cone: 32π cubed unit

Step-by-step explanation:

Volume of cone: V=1/3hπr²

1/3 x 6 x π x 4^2 = 32π

Answer:

The volume of a cone is 100.53. If you want to round it to the nearest one. It's 101.

Step-by-step explanation:

To find the volume. Use the equation V=3.14r^2 h/3

r=4 and h=6 so the equation is V=3.14(4^2) 6/3

V=50.24(6) = 100.53

Answer:

Slope (m) is the number being multiplied by x (make sure you include the sign in front of it).

y- intercept (b) is the number other than the x

Step-by-step explanation:

Answer:

The slope is -9 and the y intercept is 2

Step-by-step explanation:

Write the equation in slope intercept form

y= mx+b where m is the slope and b is the y intercept

y = -9x+2

The slope is -9 and the y intercept is 2
