Multiply (-3) by (+1,4

Answer:

[tex]\sf y=\sqrt{21}[/tex]

Step-by-step explanation:

Altitude:  A line segment drawn from a vertex that is perpendicular to the side opposite that vertex.

Therefore, the altitude on the given diagram is y.

The two internal triangles formed by drawing the altitude are similar to the original triangle.  If two triangles are similar, their sides are proportional in length.

[tex]\implies \sf \dfrac{segment}{altitude}=\dfrac{altitude}{segment}[/tex]

[tex]\implies \sf \dfrac{3}{y}=\dfrac{y}{7}[/tex]

[tex]\implies \sf 3 \cdot 7=y \cdot y[/tex]

[tex]\implies \sf y^2=21[/tex]

[tex]\implies \sf y=\sqrt{21}[/tex]

The surface area of the complex figure is: 582 ft².

Surface area of the complex figure = surface area of the triangular prism +  surface area of the rectangular prism - 2(area of the face of the triangular prism that joins with the rectangular prism).

Surface area of the triangular prism = (s1 + s2 + s3)L + bh = (11 + 9 + 9)5 + (11)(7)

Area of the triangular prism = 222 ft²

Surface area of the rectangular prism = 2(wl+hl+hw) = 2·(5·15+8·15+8·5) = 470 ft².

2(area of the face of the triangular prism that joins with the rectangular prism) = 2(lw) = 2(11)(5) = 110 ft²

Surface area of the complex figure = 222 + 470 - 110

Surface area of the complex figure = 582 ft².

We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.

Remember the exponent property:

[tex]\frac{a^n}{a^m} = a^{n - m}[/tex]

Here we have the expression:

[tex]\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2}[/tex]

We can reorder this to get:

[tex]\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2} = \frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2}[/tex]

The right side can be simplified to:

[tex]\frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2} = 64.04*10{12 - 3 - 2} = 64.04*10^{7}[/tex]

Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:

[tex]6.404*10^8[/tex]

Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).

Answer:

  (x, y) = (-2, 5/3)

Step-by-step explanation:

The system of equations is easily solved by substitution.

Using the given value of x, substitute for x in the first equation to find y.

  y = 2/3(-2) +3

  y = -4/3 +9/3 = 5/3

The solution is (x, y) = (-2, 5/3).

Answer:

35 585

Step-by-step explanation:

Each term is   the product of the previous two terms minus the term that is two before

3*5  - 3 = 12

5 x12 - 5   = 55

12 x 55 - 12 = 648

55 * 648  - 55 = 35 585

or each term is   term that is two before x  (term before -1)

3 (5-1) = 12

5 x (12-1) = 55

12 * (55-1) = 648

55 * ( 648-1) = 35 585

The required next term in the sequence is 35,185.

Inductive reasoning is defined as, tempting judgments by moving from the details to the fact. It's usually determined with inferential reasoning, where you move from known information to precise conclusions.

here,
Given sequence 3, 5, 12, 55, 648
The given sequence has the following pattern,
3 × 5 - 3 = 12
5 × 12 - 5 = 55
12 × 55 - 12 = 648

55 × 648 - 55 = 35,185

Thus, the required next term in the sequence is 35,185.

Problem 34

Reason:

We count the number of items inside set B. In this case there are 3 values, so that is why n(B) = 3

===========================================================

Problem 36

Answer:  [tex]\boldsymbol{n(A \cap C) = 1}[/tex]

Reason:

To be able to count the number of items inside set [tex]A \cap C[/tex], we first need to determine what this set looks like. In other words, we need to know the number(s) inside this set.

The upside down U symbol is the intersection symbol. It indicates we want to find what the sets A and C have in common. In this case, it's the value "4" and nothing else. This number is in both set A and set C at the same time. It might help to draw a venn diagram as you see below. I'm ignoring set B entirely since your teacher is not asking about the set in this problem.

We can then say [tex]A \cap C = \{4\}[/tex]

There's only one item inside this set, which is why [tex]n(A \cap C) = 1[/tex]

Step-by-step explanation:

Circumference is 2(radius) * pi.

A. 12pi   C. 24pi   B. 16pi   D. 32pi

Assuming pi is roughly 3,

A = 36

C = 72

B = 48

D = 96

A is the closest and if you actually used pi, it would be about 3.14159265 which would make the circumference slightly over 36, which 37.68 is.

Step-by-step explanation:

Define the variables:

Given information:

Percentages in decimal form:

Create a system of equations using the given information and defined variables:

[tex]\begin{cases}x + y = 28500\\0.1x - 0.04y = 1310 \end{cases}[/tex]

Rewrite Equation 1 to make y the subject:

[tex]\implies y=28500-x[/tex]

Substitute into Equation 2 and solve for x:

[tex]\implies 0.1x-0.04(28500-x)=1310[/tex]

[tex]\implies 0.1x-1140+0.04x=1310[/tex]

[tex]\implies 0.14x=2450[/tex]

[tex]\implies x=17500[/tex]

Substitute the found value of x into Equation 1 and solve for y:

[tex]\implies 17500+y=28500[/tex]

[tex]\implies y=11000[/tex]

The transformations are

The functions are given as:

f(x) = x

g(x)= x - 16

When a function is shifted right, the transformation rule is:

(x, y) = (x - h, y)

This means that the transformation is (d) A horizontal shift 16 units to the right

Since the parent function is a base linear function.

The transformation can also be represented as:

(x, y) = (x, k - h)

This gives

g(x)= x - 16

This means that the transformation is (b) A vertical shift 16 units downward.

Hence, the transformations are (b) and (d)
